How Can You See Private Tweets?

Twitter is the most popular social media app which is an American microblogging and social networking service on which users can post and interact with messages famously known as “tweets”. There are two types of users viz. registered and unregistered users and registered users can post, like, and retweet the tweets, but unregistered users can only read them. Users of Twitter can access Twitter through its website interface, through Short Message Service (SMS) or its mobile-device application software or simple app. Most users want to know how they can see private tweets.
How to see private tweets?
Twitter users can always choose to make their tweets public so anyone can see them or they can make their tweets protected so only approved followers or fans can view them. Also, there are some business Twitter users to protect their tweets so only close business contacts can view tweets that may contain strategic or commercially-sensitive information. And, there is no way to access a Twitter user’s protected tweets without his permission, so if you want to know how to view protected tweets you’ll need to follow the user and wait for them to approve your follow request. Certainly, after the approval, the user’s protected tweets will display as normal tweets that you can view from the Twitter feed on your homepage or from the other user’s Twitter home page as you see other tweets on Twitter. Now, while celebrities and businesses use their Twitter accounts to promote their projects and products, for the average user, the social media website is often more about sharing the news we care about and the details of our day-to-day lives mostly. So, you can see private twitter like this.But, you may know, while many people might not care who sees the messages they post, some would prefer to keep their thoughts and random observations private only for the selected individuals they want it to see. And, thankfully, making your Twitter account private is simple and straightforward by following these steps. Know that a private Twitter account means that whatever you post can only be seen by your followers, all of whom you have to manually approve which is a tedious job. This also means that anyone who doesn’t follow you or doesn’t have permission to view your feed won’t be able to see your tweets. Then, if you at one time had public Tweets i.e. before protecting your Tweets, those Tweets will no longer be public on Twitter or appear in public Twitter search results. But, instead of that, your Tweets will only be viewable and searchable on Twitter by you and your followers. In this way, using all the tools you can see private tweets. When your Tweets are protected, only your followers will be able to see your media and your Tweets. So, please note and keep in mind that your followers may download or re-share links to media that you share in protected Tweets. Links to media shared on Twitter are not always protected by it. So, anyone with the link to your account or post will be able to view the content. But, after you protect your Tweets, only you and your followers can read your updates or see your Tweets in Twitter search. Then, however, unprotecting your Tweets will cause any previously protected Tweets to be made public as well. So, find out how to remove your updates from Google search also. And, Twitter cannot remove content on websites other than twitter.com. Now, if your Tweets have never been public i.e., you’ve always had your Tweets protected in your settings through privacy settings, your updates should never show up in Twitter search or other public search engines when entered about you. By any means, if they are showing up in search results, change your password immediately and revoke untrusted third-party applications you have installed. And, you can also file a report with the following information on Twitter complaints. Information like, when this started happening, where you’ve seen your private updates posted and list any or all the third-party applications you use. We have some bad news for you if you have randomly sent out your Tweets, only a small percentage of your followers will see them. About thousands of Tweets are sent out every second, which means your followers’ timelines move quickly as you speak. Like this, you can see private Tweets. So, to increase the visibility of your Tweets, you need to send them out at the right time as well. We have performed some research on the best times to post to social media and also collected the different data to get to the perfect range for you. And that is exactly what you should be doing, i.e. rely on the best ranges instead of an exact time to post, otherwise, you will go mad trying to pinpoint exact times and make your content too routine. How you can see private Tweets is the frequent question.Also, try sharing the same content on multiple days, at different times, to get more impressions and engagement by followers. But, if you are worried about seeming too repetitive by sharing the same piece of content five days in one week, don’t worry. Even though you are sharing the same thing multiple times, the likelihood of the same users seeing it each time is quite slim. So, you are never going to send out a Tweet that all of your followers see. And, the main goal is to be seen by as many as possible. Now, getting the results with Twitter isn’t going to happen overnight you know. It’s all about building connections and relationships, which takes a lot more time than you think of.
About
Twitter is one popular platform where you mostly see tweets which helps you know about what people share about their life. Many want to know how they can see private Tweets without following so what they need to do is use some third-party tools or applications or use various innovative methods to see private twitter.
Conclusion
In this way, you can see private tweets using various third-party tools and various methods that allow you to hack these private accounts on Twitter so that you can see them.

Well, using third-party tools you can view protected tweets. There is absolutely no way to access a protected tweet without users’ permission, so if you want to view protected tweets you’ll need to follow the user and wait for him to approve your follow request. After approval, the user’s protected tweets will display as normal tweets that you can view from the Twitter feed on your homepage or from the other user’s Twitter home page. When you create an account, your profile is public by default option. Your Tweets can be seen by up to 271 million active users. This can be a little overwhelming if you’re a private user. So, following different methods, you can view private tweets. If you want to use Twitter to chat with family and friends, having so many eyes on your content might not be what you like. So, what can be done? Well, you could protect your Tweets. Protected Tweets gives you privacy and the ability to control your information, similarly to how a private Facebook profile can restrict everyone but your friends from seeing your updates. With Twitter’s user base rapidly growing and brands, family, and friends creating accounts, sometimes you just want to create an account to communicate with them privately. This is where using protected Tweets and a private account is perfect for the users. One of the best privacy features on Twitter is that it lets you control how people can look you up on Twitter account. In the Settings, look for a section on the option Discoverability where you can choose if other users can find you on Twitter using your email address or phone number. You can also view and manage any contacts you have uploaded to Twitter or choose to remove uploaded data from your account. You will see the option for Account Privacy here which gives you the option to switch to a private account. Once enabled, only followers who have followed you will be able to see your posts. Any new followers will have to be approved by you personally. You can do this as you like, if you’re not interested in growing many followers and want to share with a group of people only. So, chances are that you have linked your Facebook profile to your Twitter account — either by choice or by using a Facebook account to login to Twitter. What happens in this scenario is that when anyone visits your Facebook profile, it shows them that you are also available on Twitter. To avoid this, head to your Settings in your Twitter app, then tap on the following options Account > Linked Accounts > Facebook, and select ‘Unlink Account’.

Even with your Twitter account set to private, a friend can share your story to their timeline and it would then become public through their feed. To stop this action from happening, you can control how your tweets can be seen and shared. In the Settings, you can go to Privacy and Security then to Story Controls, where, you can switch off the option that lets people share your tweets. You can create a blacklist of users to hide your tweets from certain people, you can choose who can reply to your story i.e. everyone.

Sym: A Command Line Utility and A Ruby API for Coding

Sym — Symmetric Encryption for Humans

NotePlease checkout the following post — Dead Simple Encryption with Sym — that announced the initial release of this library, and provides further in-depth discussion. Your donation of absolutely any amount is much appreciated but never required.

Donate

NoteYou can read this README in the properly rendered for print format, by downloading the PDF.

Introduction

NoteSYM is an open source command line utility and a Ruby library, which makes it _trivial to encrypt your application secrets with mathematically proven models and ciphers offered in a much larger project — Open SSL.

Unlike many existing encryption tools, sym focuses on narrowing the gap between convenience and security, by offering enhanced usability and a streamlined ruby API and a CLI. The primary goal of the library is to make encryption very easy and transparent.
 

sym uses the Symmetric Encryption algorithm. This means that the same key is used to encrypt and decrypt data. In addition to the key, the encryption uses a randomized IV vector, which is automatically generated per each encryption and serialized with the data. Result of encryption is zlib-compressed, and base64 encoded, to be suitable for storage as string. The generated keys are also base64-encoded for convenience.
 

Finally, the library offers encryption using any regular password, and in particular supports password-protected encryption keys. Automatic key detection algorithm attempts to resolve a provided key as a filename, an environment variable name, an OS-X Keychain password entry name, a key itself, or a default key file.
 

NoteSym uses Ruby’s Marshall.dump to serialize it’s data, and therefore it is not currently possible or easy to deserialize the data in languages other than Ruby.

Quick Demo of the CLI in Action

asciicast

Help Screens, Examples and Symit Bash Wrapper

This may be a good time to take a look at the full help message for the sym tool, shown naturally with a -h or --help option. Examples can be shown with -E/--examples flag.

Additionally, Sym comes with a helpful BASH wrapper symit.

Help screens for sym and symit are shown in full on another page — Sym Help Screens and Symit. Please refer to it for complete help screens and the examples.

Supported Ruby Versions

NoteRuby 3.0.0 is only supported by Sym version 3.0.1 and later.

Sym currently builds and runs on the following ruby versions on Travis CI:

Table 1. Ruby Version Compatibility

MRI RubyJRuby
2.3.8jruby-9.1.17.0
2.4.10jruby-9.2.13.0
2.5.8 
2.6.6 
2.7.1 

Motivation

The main goal when writing this tool was to streamline and simplify handling of sensitive data in a trasparent and easy to use way without sacrificing security.

Most common use-cases include:

Encrypting/decrypting of application secrets files, so that the encrypted secrets can be safely checked into the git repository and distributed, and yet without much of the added headache that this often requires

Secure message transfer between any number of receipients

General purpose encryption/decryption with a 256-bit encryption key, optionally itself re-encrypted with a password.

General purpose encryption/decryption with an arbitrary password.

Sym is a layer built on top of the OpenSSL library, and, hopefully, makes encryption more accessible to every-day developers, QA, and dev-ops folks, engaged in deploying applications.

What’s Included

This gem includes two primary components:

Rich command line interface CLI with many features to streamline encryption/decryption, and to be integrated into the deployment flow.
 

Ruby APIs:

Key Generation, Encryption & Decryption API

is activated by including Sym module in a class, it adds easy to use encr/decr methods.

Application API to shadow the CLI usage

You can instantiate Sym::Application class with a hash representing CLI arguments, and then call it’s #execute method to mimic CLI execution.

Sym::MagicFile API

This is a convenience class allowing you to encrypt/decrypt files in your ruby code with just couple of lines of code.

Sym::Configuration

Use this class to override the default cipher, and configure other parameters such as compression, password caching, and more.

Massive Time Savers

Sym tries very hard to get out of your way, to make it feel as if your encrypted files are as easy to work with as the unencrypted files. It accomplishes this transparency with the following features:

By using Mac OS-X Keychain, sym offers a simple yet secure way of storing the key on a local machine, much more secure then storing it on a file system.

By using a password cache (-c) via an in-memory provider such as memcached, sym invocations take advantage of password cache, and only ask for a password once per a configurable time period.

By using SYM_ARGS environment variable you can save common flags and they will be applied whenever -A flag is activated.

By reading a key from the default key source file ~/.sym.key which requires no flags at all.

By utilizing the --negate option to quickly encrypt a regular file, or decrypt an encrypted file with extension .enc.

By using the -t file (edit) mode, that opens an encrypted file in your $EDITOR, and replaces the encrypted version upon save & exit.

As you can see, we really tried to build a tool that provides good security for application secrets, including password-based encryption, but does not annoyingly ask for password every time. With --edit option, and --negate options you can treat encrypted files like regular files.

Encrypting application secrets had never been easier! ---

— Socrates (LOL)

Using Sym

Installation

If you plan on using the library in your Ruby project with Bundler managing its dependencies, just include the following line in your Gemfile:

gem 'sym'

And then run bundle.

Or install it into the global namespace with gem install command:

$ gem install sym
$ sym -h
$ sym -E # see examples

BASH Completion

Optionally, after gem installation, you can also install bash-completion of gem’s command line options, but running the following command (and feel free to use any of the "dot" files you prefer):

sym -B ~/.bashrc

Should you choose to install it (this part is optional), you will be able to use "tab-tab" after typing sym, and you’ll be able to choose from all of the supported flags.

Typical Use-Case Scenario

You generate a new encryption key, that will be used to both encrypt and decrypt the data. The key is 256 bits, or 32 bytes, or 45 bytes when base64-encoded, and can be generated with sym -g. The key must be saved somewhere for later retrieval. The key should not be easily accessible to an attacker. Note, that while generating the key, you can:

optionally password protect the key with sym -gp

save the key into a file with sym -gpo key-file

save it into the OS-X Keychain, with sym -gpx keychain-name

cache the password, with sym -gpcx keychain-name

Normally, sym will print the resulting key to STDOUT

You can prevent the key from being printed to STDOUT with -q/--quiet.

Next, let’s assume you have a file or a string that you want to encrypt. We call this data.

In order to encrypt the data, we must supply an encryption key. Flag -k automatically retrieves the key, by trying to read it in several distinct ways, such as:

a file with a pathname specified by the argument (eg, -k ~/.key)

or environment variable (eg -k ENC_KEY)

or OS-X Keychain entry

verbatum string argument (not recommended)

alternatively, you can paste the key interactively with -i or save the default key in ~/.sym.key file.

Finally, we are ready to encrypt. The data to be encrypted can be read from a file with -f filename, or it can be read from STDIN, or a passed on the command line with -s string. For example, sym -e -k ~/.key -f /etc/passwd will encrypt the file and print the encrypted contents to STDOUT.

Instead of printing to STDOUT, the output can be saved to a file with -o <file> or a simple redirect or a pipe.

Encrypted file can later be decrypted with sym -d ... assuming the same key it was encrypted with.

Encrypted file with extension .enc can be automatically decrypted with -n/--negate file option; if the file does not end with .enc, it is encrypted and .enc extension added to the resulting file.

With -t/--edit file flag you can edit an encrypted file in VIM (or $EDITOR) any encrypted file and edit it. Once you save it, the file gets re-encrypted and replaces the previous version. A backup can be created with -b option. See the section on inline editing

A sample session that uses Mac OS-X Keychain to store the password-protected key.

# Gen a new key, password-encrypt it, cache the password, save
# result in the key chain entry 'my-new-key' (but don't print it '-q')
❯ sym -gpqcx my-new-key
New Password     :  •••••••••
Confirm Password :  •••••••••

❯ sym -eck my-new-key -s 'My secret data' -o secret.enc
Password: •••••••••

❯ cat secret.enc
BAhTOh1TeW06OkRhdGE6OldyYXBFefDFFD.....

❯ sym -dck my-new-key -f secret.enc
My secret data

# Now, let's save our keychain key in the default key file:
❯ sym -ck my-new-key -o ~/.sym.key

# Now we can decrypt/encrypt with this key at will
❯ sym -n secret.enc
# created a decrypted file `secret`

# Lets now save common flags in the SYM_ARGS bash variable:
❯ export SYM_ARGS="-ck my-new-key"
# To have sym parse the SYM_ARGS variable, we must activate this feature with -A
❯ sym -Adf secret.enc
My secret data

Note that password caching is off by default, but is enabled with -c flag. In the example above, the decryption step fetched the password from the cache, and so the user was not required to re-enter the password.

 

Inline Editing of Encrypted Files

The sym CLI tool supports one particularly interesting mode, that streamlines handling of encrypted files. The mode is called edit mode, and is activated with the -t flag.

Instead of decrypting data anytime you need to change it into a new file and then manually re-encrypting the result, you can use the shortcut flag -t (for "edit"), which decrypts your data into a temporary file, automatically opening it with an $EDITOR.

sym -t config/application/secrets.yml.enc -k ~/.key

This is one of those time-saving features that can make a difference in making encryption feel easy and transparent.

Notethis mode does not seem to work with GUI editors such as Atom or TextMate. Since sym waits for the editor process to complete, GUI editors "complete" immediately upon starting a windowed application.

In this mode several flags are of importance:

-b (--backup)   – will create a backup of the original file
-v (--verbose) - will show additional info about file sizes

Here is a full command that opens a file specified by -f | --file, using the key specified in -k | --keyfile, in the editor defined by the $EDITOR environment variable (or if not set — defaults to /bin/vi)".

Example: here we edit an encrypted file in vim, while using interactive mode to paste the key (-i | --interactive), and then creating a backup file (-b | --backup) upon save:

sym -ibt data.enc
# => Private Key: ••••••••••••••••••••••••••••••••••••••••••••

Ruby API

Including Sym module

Low-level encryption routines can be imported by including Sym module into your class or a module. Such class will be decorated with new class methods #private_key and #create_private_key, as well as instance methods #encr, and #decr.

Class Method #create_private_key()

This method will generate a new key each time it’s called.

Class Method #private_key(value = nil)

This method will either assign an existing key (if a value is passed) or generate and save a new key in the class instance variable. Therefore each class including Sym will (by default) use a unique key (unless the key is passed in as an argument).

The following example illustrates this point:

require 'sym'

class TestClass
  include Sym
end

@key = TestClass.create_private_key
@key.eql?(TestClass.private_key)  # => false
# A new key was created and saved in #private_key accessor.

class SomeClass
  include Sym
  private_key TestClass.private_key
end

@key.eql?(SomeClass.private_key)  # => true (it was assigned)

Encrypting and Decrypting

So how would we use this library from another Ruby project to encrypt and decrypt values?

After including the Sym module, two instance methods are added:

#encr(value, private_key) and

#decr(value, private_key).

Therefore you could write something like this below, protecting a sensitive string using a class-level secret.

require 'sym'
class TestClass
  include Sym
  private_key ENV['SECRET']

  def sensitive_value=(value)
    @sensitive_value = encr(value, self.class.private_key)
  end
  def sensitive_value
    decr(@sensitive_value, self.class.private_key)
  end
end

Encrypting the Key Itself

You can encrypt the private key using a custom password. This is highly recommended, because without the password the key is the only piece that stands between an attacker and decrypting your sensitive data.

For this purpose, two more instance methods exist:

#encr_password(data, password, iv = nil)

#decr_password(encrypted_data, password, iv = nil)

They can be used independently of encr and decr to encrypt/decrypt any data with a password.

 

Using Sym::MagicFile API for Reading/Writing Encrypted/Decrypted data

This is probably the easiest way to leverage Sym-encrypted files in your application — by loading them into memory with Sym::MagicFile. This class provides a very simple API while supporting all of the convenience features of the rich application API (see below).

You instantiate Sym::MagicFile with just two parameters: a pathname to a file (encrypted or not), and the key identifier. The identifier can either be a filename, or OS-X Keychain entry, or environment variable name, etc — basically it is resolve like any other -k <value> CLI flag.

The following methods are available:

#encrypt — returns an encrypted string representing the encrypted contents ofa file specified by the pathname.

#decrypt — returns a decrypted string representing the decrypted contents of a file specified by the pathname.

#encrypt_to(filename) — encrypts the contents of a file specified by the pathname, and writes the result to a filename.

#decrypt_to(filename) — decrypts the contents of a file specified by the pathname, and writes the result to a filename.

Example: Using Sym::MagicFile with the RailsConfig (or Settings) gem

In this example, we assume that the environment variable $PRIVATE_KEY contain the key to be used in decryption.

require 'sym/magic_file'
require 'yaml'
secrets = Sym::MagicFile.new('/usr/local/etc/secrets.yml.enc', 'PRIVATE_KEY')
hash = YAML.load(secrets.decrypt)

Let’s say that you are using RailsConfig gem for managing your Rails application setings. Since the gem allows appending settings from a hash, you can simply do the following in your settings_initializer.rb, and after all of the unencrypted settings are loaded:

require 'config'
require 'sym/magic_file'
require 'yaml'
Settings.add_source!(
    YAML.load(
        Sym::MagicFile.new(
            '/usr/local/etc/secrets.yml.enc',
            'PRIVATE_KEY'
        ).decrypt)
    )
Settings.reload!

 

Using Sym::Application API

Since the command line interface offers much more than just encryption/decryption of data with a key, majority of these features are available through Sym::Application instance.

The class is instantiated with a hash that would be otherwise generated by parsing CLI arguments, typical options. For example, to generate the key, pass generate: true — essentially any flag in it’s long form can be converted into a hash member.

Here is an example:

require 'sym/application'

key  = Sym::Application.new(generate: true).execute
# => '75ngenJpB6zL47/8Wo7Ne6JN1pnOsqNEcIqblItpfg4='

Ruby API Conclusion

Using Sym's rich ruby API you can perform both low-level encryption/decryption, as well as high-level management of encrypted files. By using Sym::MagicFile and/or Sym::Application classes you can access the entire set of functionality expressed vi the CLI, described in details below.

 

Using sym with the Command Line

Encryption Keys

The private key is the cornerstone of the symmetric encryption. Using sym, the key can be:

generated and printed to STDOUT, or saved to Mac OS-X KeyChain or a file

fetched from the Keychain in subsequent operations

password-protected during generation (or import) with the -p flag.

password can be cached using a locally running memcached, assuming the -c flag is provided.

must be kept very well protected and secure from attackers.

The unencrypted private key will be in the form of a base64-encoded string, 45 characters long.

Encrypted (with password) private key will be considerably longer, perhaps 200-300 characters long.

Generating the Key — Examples

# Let's generate a new key, and copy it to the clipboard (using `pbcopy` command on Mac OS-X):
$ sym -g | pbcopy

# Or save a new key into a bash variable
$ KEY=$(sym -g)

# Or save it to a file:
$ sym -go ~/.key

# Or create a password-protected key (`-p`), and save it to a file (`-o`),
# cache the password (`-c`), and don't print the new key to STDOUT (`-q` for quiet)
$ sym -gpcqo ~/.secret
New Password:     ••••••••••
Confirm Password: ••••••••••
$

Resolving the -k Argument

You can use the generated private key by passing an argument to the -k flag.

Sym attempts to automatically resolve the key source by trying each of the following options, and then moving on to the next until the key is found, or error is shown:

the -k value flag, where the value is one of:

a file path, eg (-k ~/.key)

an environment variable name (-k MY_KEY)

an actual base64-encoded key (not recommended for security reasons)

a keychain name (-k keychain-entry-name)

pasting or typing the key with the -i (interactive) flag

if exists, a default key file, located in your home folder: ~/.sym.key is used only when no other key-specifying flags were passed in.

Encryption and Decryption

 

Inline Editing

The sym CLI tool supports one particularly interesting mode, that streamlines handling of encrypted files. The mode is called edit mode, and is activated with the -t file flag.

In this mode sym will automaticaly decrypt the encrypted file into a temporary file, and then open it in $EDITOR. Once you quit the editor, sym will automatically diff the new and old content, and if it is different, sym will re-encrypt the new contents and overwrite the original file. You can create an optional backup by adding -b flag.

Notethis mode does not seem to work with GUI editors such as Atom or TextMate. Since sym waits for the editor process to complete, GUI editors "complete" immediately upon starting a windowed application. In this mode several flags are of importance:
-b (--backup)   – will create a backup of the original file
-v (--verbose) - will show additional info about file sizes

Here is a full command that opens a file specified by -t | --edit file, using the key specified in -k | --keyfile, in the editor defined by the $EDITOR environment variable (or if not set — defaults to /bin/vi)".

To edit an encrypted file in $EDITOR, while asking to paste the key (-i | --interactive), while creating a backup file (-b | --backup):

 sym -tibf data.enc

Using KeyChain Access on Mac OS-X

KeyChain storage is a huge time saver. It allows you to securely store the key the keychain, meaning the key can not be easily extracted by an attacker without a login to your account. Just having access to the disk is not enough.

Apple had released a security command line tool, which this library uses to securely store a key/value pair of the key name and the actual private key in your OS-X KeyChain. The advantages of this method are numerous:

The private key won’t be lying around your file system unencrypted, so if your Mac is ever stolen, you don’t need to worry about the keys running wild.

If you sync your keychain with the iCloud you will have access to it on other machines

As mentioned previously, to add the key to the KeyChain on the Mac, use -x <key-name> flag with -g flag when generating a key. The key name is what you call this particular key, based on how you plan to use it. For example, you may call it staging, etc.

The following command generates the private key and immediately stores it in the KeyChain access under the name provided:

sym -gx staging   # the key is passwordless
sym -gpcx staging # this key is password protected, with the password cached

Next, whenever you need to use this key, you can specify the key with -k staging.

Finally, you can delete a key from KeyChain access by running:

keychain <name> delete

Below we describe the purpose of the executable keychain shipped with sym.

KeyChain Key Management

keychain is an additional executable installed with the gem, which can be used to read (find), update (add), and delete keychain entries used by sym.

It’s help message is self-explanatory:

Usage: keychain <name> [ add <contents> | find | delete ]

Moving a Key to the Keychain

You can easily move an existing key from a file or a string to a keychain by combining -k or -k to read the key, with -x to write it.

sym -k $keysource -x mykey

Adding Password to Existing Key

You can add a password to a key by combining one of the key description flags (-k, -i) and then also -p. Use -q to hide new key from the STDOUT, and c to cache the password.

sym -k $mykey -pqcx moo

The above example will take an unencrypted key passed in $mykey, ask for a password and save password protected key into the keychain with name "moo."

Password Caching

Nobody likes to re-type passwords over and over again, and for this reason Sym supports password caching via a locally running memcached instance (using the default port 11211, if available).

Multiple Providers

Cache is written using the Provider design pattern (a.k.a. plugin architecture), and so it’s easy to add a new Cache Provider that uses a custom backend. The supplied production-ready provider only works with a memcached daemon running (ideally) locally.

For customization of memcached location, we refer you to the Configuration class for an example of how to configure MemCached provider — shown below in the Ruby API section.

In order to control password caching, the following flags are available:

-c turns on caching

-u seconds sets the expiration for cached passwords

-r memcached controls which of the providers is used. Without this flag, sym auto-detects caching provider by first checking for memcached

Saving Common Flags in an Environment Variable

You can optionally store frequently used flags for sym in the SYM_ARGS environment variable. For example, to always cache passwords, and to always use the same encryption key from the keychain named "production", set the following in your ~/.bashrc:

export SYM_ARGS="-cx production"

This will be automatically appended to the command line if the -A/--sym-args flag is provided, and so to encrypt/decrypt anything with password caching enabled and using that particular key, you would simply type:

# -cx production are added from SYM_ARGS
sym -Aef file -o file.enc

# And to decrypt:
sym -Adf file.enc -o file.original

# Or edit the encrypted file:
sym -Atf file.enc

Fine Tuning

 

Configuration

The library contains a Sym::Configuration singleton class, which can be used to tweak some of the internals of the gem. Its meant for advanced users who know what they are doing. The code snippet shown below is an actual default configuration. You can override the defaults by including a similar snipped in your application initialization, right after the require 'sym'. The Configuration class is a Singleton, so changes to it will propagate to any subsequent calls to the gem.

require 'zlib'
require 'sym'
Sym::Configuration.configure do |config|
  config.password_cipher          = 'AES-128-CBC'
  config.data_cipher              = 'AES-256-CBC'
  config.private_key_cipher       = config.data_cipher
  config.compression_enabled      = true
  config.compression_level        = Zlib::BEST_COMPRESSION
  config.encrypted_file_extension = 'enc'
  config.default_key_file         = "#{ENV['HOME']}/.sym.key"

  config.password_cache_timeout          = 300

  # When nil is selected, providers are auto-detected.
  config.password_cache_default_provider = nil
  config.password_cache_arguments        = {
    # In-memory password cache configuration:
    # Memcached Provider – local is the default, but can be changed.
    memcached: {
      args: %w(127.0.0.1:11211),
      opts: { namespace:  'sym',
              compress:   true,
              expires_in: config.password_cache_timeout
      }
    }
  }
end

As you can see, it’s possible to change the default cipher type, although not all ciphers will be code-compatible with the current algorithm, and may require additional code changes.

Encryption Features & Cipher

The sym executable as well as the Ruby API provide:

Symmetric data encryption with:

the Cipher AES-256-cBC used by the US Government

256-bit private key, that

can be generated and is a base64-encoded string about 45 characters long. The decoded key is always 32 characters (or 256 bytes) long.

can be optionally password-encrypted using the 128-bit key, and then be automatically detected (and password requested) when the key is used

can optionally have its password cached for 15 minutes locally on the machine using memcached

Rich command line interface with some innovative features, such as inline editing of an encrypted file, using your favorite $EDITOR.

Data handling:

Automatic compression of the data upon encryption

Automatic base64 encryption to make all encrypted strings fit onto a single line.

This makes the format suitable for YAML or JSON configuration files, where only the values are encrypted.

Rich Ruby API

(OS-X Only): Ability to create, add and delete generic password entries from the Mac OS-X KeyChain, and to leverage the KeyChain to store sensitive private keys.

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install.

To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
