Crypter: an innovative, Convenient and Secure Encryption App


An innovative, convenient and secure crypto app.

Encrypt unlimited bits. Remember only a bit.

Crypter is a cross-platform crypto app that makes encryption and decryption convenient while still upholding strong security. It tackles one of the weakest links in most security systems today - weak passwords. It simplifies secure password generation and management and requires you to only remember one bit - your MasterPass.

Crypter v4.0 is a crypto app that can decrypt and encrypt any arbitrary data this includes files and folders. This version has been released and fully tested for macOS (OSX), Linux (for all distros via AppImage) and Windows (32 & 64 bit). All core modules (modules that provide the core functionality) are fully tested.

Crypter v5.0 will save your MasterPass in your OS's Keychain so you won't have to enter it every time you open the app. To help speed up the development please send a PR for what's left do

Please open an issue if you have any suggestions and add improvements via PRs!

All prebuilt binaries for all major platforms are available under releases.

Crypter is also on Homebrew Cask for macOS. So to install it, simply run the following command in the Terminal:

$ brew install --cask crypter@4.0.0

One key to derive them all!

Crypter derives a MasterPassKey from the MasterPass obtained at setup by using the PBKDF2 key derivation algorithm (see below for the specification). It then uses PBKDF2 to derive a number of encryption keys from the MasterPassKey that can be used for the encryption of files. This method allows for the generation of very secure encryption keys for data encryption. Moreover, by publicly storing the credentials used to derive the MasterPassKey and the salts used to derive the encryption keys, you are able to produce the encryption keys at will and without needing to store them securely. Your MasterPass is the only thing that you need to remember.

Crypter never directly encrypts anything with your MasterPass. Instead, it derives a MasterPassKey from it, which it then uses to derive the encryption key used to encrypt your file. Every time a file is decrypted, the encryption key is re-derived from the MasterPassKey. Every time you set the MasterPass through the setup or reset it through Verify MasterPass, the MasterPassKey is derived from the MasterPass using a newly generated set of (random) credentials. These credentials are used to re-derive the MasterPassKey every time that Crypter is executed (i.e. the app is launched).

Authentication with the AES-256-GCM symmetric block cipher is used by default. This ensures that data integrity is verified on decryption and allows the app to detect tampering or data corruption.

The following are the crypto defaults and can be found under app/config.js:

// Crypto defaults
  ITERATIONS: 50000, // file encryption key derivation iterations
  KEYLENGTH: 32, // encryption key length
  IVLENGTH: 12, // initialisation vector length
  ALGORITHM: 'aes-256-gcm', // encryption algorithm
  DIGEST: 'sha256', // digest function
  HASH_ALG: 'sha256', // hashing function
  MPK_ITERATIONS: 100000 // MasterPassKey derivation iterations

Encryption process

When encrypting a file, Crypter first creates a temporary hidden directory, namely '.crypting'. It then encrypts the user-selected file with the crypto defaults and flushes the encrypted data to a file in the directory, namely 'data'. If it is a directory then it is compressed first (tar). It also writes the public credentials to a file within the same directory, namely 'creds'. Finally, Crypter compresses the directory to a tar archive with the name of the user-selected file and the '.crypto' extension appended to it.

Decryption process

The decryption process is essentially the inverse of the encryption process. During decryption, Crypter creates a temporary hidden directory named '.decrypting'. It then reads the credentials from the creds file and decrypts the data file into the original file or directory (after decompressing it) with its original name and extension, as deduced from the CRYPTO file name (e.g. the extension for "file.txt.crypto" would be ".txt").

Public credentials

Certain credentials are required to decrypt the encrypted data. These are needed to reconstruct the particular encryption key and to verify data integrity. These can be stored publicly without compromising security since it is fairly impossible (by current standards) to reconstruct the encryption key without the MasterPass and its credentials. These credentials are stored in the creds file of the CRYPTO file archive (as delineated above) in the following format:





  "type": "CRYPTO",
  "iv": "...",
  "authTag": "...",
  "salt": "...",
  "isDir": true || false

The dir part is only included for directories



A CRYPTO file is the product of the Crypter encryption process. This file stores both the encrypted version of the user file and the public credentials needed to encrypt and decrypt it. It has a .crypto file extension, which is appended to the full file name (including the extension) of the file originally encrypted. The file itself is a tar archive in the following structure:

├── data // the encrypted version of the user selected file
└── creds // the public credentials used to encrypt it

Reusing the same MasterPass

If you attempt to decrypt a CRYPTO file by resetting to a specific MasterPass or setting an identical MasterPass on a different machine, you will likely encounter the following error:

ERROR: Unsupported state or unable to authenticate data

This issue occurs because the MasterPassKey that was originally used to derive the encryption key on is not the same as the MasterPassKey derived with the reused MasterPass. Since Crypter uses randomness to generate secure credentials, this second set of credentials will be quite different from the original set. As a result, the derived encryption key is incorrect and yields this error.

See Achieving portability and same MasterPass reuse for instructions on how to successfully reuse the same MasterPass.

Achieving portability and same MasterPass reuse

To achieve portability on Crypter, the set of MasterPassKey credentials need to be exported from Crypter on the source machine1 and imported into Crypter on the target machine2.

This can be achieved in two simple steps:

  1. Export MasterPass credentials on the source machine1
  2. Import MasterPass credentials on the target machine2

Please refer to the FAQs for instructions on how to perform the above steps.

[1] The machine where the CRYPTO file was initially encrypted.

[2] The machine where you wish to decrypt the CRYPTO file.


Security-first practice

Crypter follows a security-first practice. This means that security is its highest priority and first consideration. Thus, while Crypter seeks to make encryption more convenient, it always defers to maintaining a high level of security.


Crypter never stores your MasterPass in memory or on the filesystem. This substantially improves the security of your MasterPass. You are only asked to enter the MasterPass when you first set, reset or verify it. Whenever you enter your MasterPass, Crypter derives a MasterPassKey (using a set of generated credentials) and then immediately discards the MasterPass. The MasterPassKey is then securely stored in memory and used to derive the encryption keys. Since these credentials are derived via a one-way function, they cannot be used in any way to derive the MasterPass.


Crypter uses a WeakMap to store the MasterPassKey inside the MasterPassKey class using a closure function. This makes the MasterPassKey data held in the object (externally) inaccessible, consequently increasing the protection of the MasterPassKey. The MasterPassKey is never flushed to the filesystem and is always stored in (main) memory. Since JS does not give control over or allow such a low-level operation as wiping memory, the program relies on the garbage collection and volatility of the main memory for the permanent erasure of the MasterPassKey stored in memory.

A decent number of iterations (see the above specifications) are used in the derivation of the MasterPassKey to mitigate brute-force attacks. A good amount of iterations are also used during the derivation of the encryption keys from the MasterPassKey. Consequently, performance and speed are not significantly compromised. For critical applications, you may choose to select 10,000,000 iterations instead of the default number (in app/core/crypto.js). Please refer to for more information.

Crypter generates a new set of random credentials for deriving the MasterPassKey every time the MasterPass is set (at setup) or reset. Crypter employs randomness to mitigate brute-force attacks and thus drastically improve security.


How do I encrypt a file or folder?

If you haven't already, walk through the setup and set your MasterPass. To encrypt a file or folder, first launch Crypter and verify your MasterPass. After doing so successfully, you will see the main Crypter window with an orange area. Here, you can simply drag-and-drop or click to select the file/folder you wish to encrypt. Once Crypter is done encrypting your file/folder, it will show you the encryption information (i.e. the encryption key and the path of the encrypted file) in a new window. To encrypt another file/folder simply click the back arrow at the bottom left and start-over ;)

How do I decrypt a CRYPTO file?

The following instructions assume that the CRYPTO file that you wish to decrypt is being used with the same MasterPass that you set at setup and also that you have not reset it since that time. If this is not the case, please refer to Reusing the same MasterPass.

To decrypt a CRYPTO file, first launch Crypter and verify your MasterPass. After doing so successfully, you will see the main Crypter window with an orange area. Here, you can simply drag-and-drop or click to select the CRYPTO file that you wish to decrypt. After a few seconds, the process will complete and you will see some information about the file and its original encryption in a new window. By default, the decrypted file has the same name as the name of the original file (i.e. the encrypted file name without the .crypto at the end).

How do I encrypt multiple files?

Crypter can encrypt an entire folder so you can put them in a folder or, alternatively, compress them into an archive (like a .zip) and then just pass it to Crypter ;)

Why am I getting the "Corrupted Crypter file or trying to decrypt on a different machine." error?

This error means that either your Crypter file (i.e. the data file) is corrupt/tempered, that you are on a different machine than the one originally used to encrypt the file or that you have previously reset your MasterPass. For the last two cases, please refer to Reusing the same MasterPass and Achieving portability and same MasterPass reuse.

Why can't I decrypt a CRYPTO file on a different machine with the same MasterPass?

Please refer to Reusing the same MasterPass and Achieving portability and same MasterPass reuse

Why can't I decrypt a CRYPTO file with the same MasterPass?

Please refer to Reusing the same MasterPass and Achieving portability and same MasterPass reuse

Where are my encrypted/decrypted files/folders placed?

By default, every source file that you encrypt/decrypt gets encrypted/decrypted to the same directory where the source file is located.

How can I access Crypter's preferences?

You can access Crypter's preferences by either clicking on the cog icon in the main Crypter window or by going to Crypter > Preferences... from the menu.

How can I reset my MasterPass?

You can reset your MasterPass by clicking on the "Forgot it" link in the Verify MasterPass window. This takes you to a new screen where you can enter a new, valid MasterPass. Once you've entered it, click the 'Reset' button and you'll be sent back to the verify screen where you can verify your new MasterPass.

What is a valid MasterPass?

Crypter will not allow you to set an invalid MasterPass. A MasterPass is valid when it adheres to the following rules:

  • It is at least 8 characters long
  • It has at least one uppercase alphabetic character (A-Z)
  • It has at least one lowercase alphabetic character (a-z)
  • It has at least one numeric character (0-9)
  • It has at least one special character ($@!%*#?&)

These rules are enforced via the following regular expression:


What are MasterPass credentials?

MasterPass credentials are a set of values that are required to derive the MasterPassKey from the MasterPass. These values have a pseudo-random element and are cryptographically linked. Every MasterPass that is set or reset with Crypter has a unique set of MasterPass credentials. These yield a distinct MasterPassKey, even when a MasterPass is reused.

How can I export my MasterPass credentials?

To export your MasterPass credentials, you can first open Crypter's preferences (see above). From this screen, click on the "Export" button. A dialog will appear from which you can select the folder where you wish to export the credentials. A success message will confirm a successful export. The exported MasterPass credentials file is always named credentials.crypter.

How can I import my MasterPass credentials?

To import a set of MasterPass credentials, you can first open Crypter's preferences (see above). From this screen, click on the "Import" button. A dialog will appear from which you can locate your credentials.crypter file. After you select it, a success message will confirm a successful import and you will have to verify the MasterPass for the credentials.

NOTE: while Crypter does not require the MasterPass credentials file to be exactly named credentials.crypter, it does require the file's contents to be unaltered from when it was exported from Crypter. If it has been altered, the import may fail.


Crypter is developed in the "dev" branch, which may be unstable at times. This branch should typically be used for pull requests.

The "master" branch will always be kept stable.


All major configurations that you can apply are found under app/config.js. This includes changes to certain cryptography settings. Please be advised that altering these may break functionality and portability.

Install (dependencies)

To install all dependencies, run:

$ yarn install


Since Crypter uses gulp, please install it globally if you have not already done so. To start Crypter, run:

$ gulp


Crypter primarily uses mocha and chai for testing. Since the project uses a lot of JS ES6 syntax, babel is also used as a transpiler. To run all the tests, execute:

$ yarn test

Crypter uses istanbul for coverage. To run test coverage, execute:

$ yarn run coverage


Crypter's binaries (available under releases) have been built using Electron. Since Crypter uses electron-builder to build binaries, you must install it globally:

$ npm install electron-builder@next -g

How to start an electric scooter facility/fleet in a university campus/IT park

Are you leading an organization that has a large campus, e.g., a large university? You are probably thinking of introducing an electric scooter/bicycle fleet on the campus, and why wouldn’t you?

Introducing micro-mobility in your campus with the help of such a fleet would help the people on the campus significantly. People would save money since they don’t need to use a car for a short distance. Your campus will see a drastic reduction in congestion, moreover, its carbon footprint will reduce.

Micro-mobility is relatively new though and you would need help. You would need to select an appropriate fleet of vehicles. The people on your campus would need to find electric scooters or electric bikes for commuting, and you need to provide a solution for this.

To be more specific, you need a short-term electric bike rental app. With such an app, you will be able to easily offer micro-mobility to the people on the campus. We at Devathon have built Autorent exactly for this.

What does Autorent do and how can it help you? How does it enable you to introduce micro-mobility on your campus? We explain these in this article, however, we will touch upon a few basics first.

Micro-mobility: What it is


You are probably thinking about micro-mobility relatively recently, aren’t you? A few relevant insights about it could help you to better appreciate its importance.

Micro-mobility is a new trend in transportation, and it uses vehicles that are considerably smaller than cars. Electric scooters (e-scooters) and electric bikes (e-bikes) are the most popular forms of micro-mobility, however, there are also e-unicycles and e-skateboards.

You might have already seen e-scooters, which are kick scooters that come with a motor. Thanks to its motor, an e-scooter can achieve a speed of up to 20 km/h. On the other hand, e-bikes are popular in China and Japan, and they come with a motor, and you can reach a speed of 40 km/h.

You obviously can’t use these vehicles for very long commutes, however, what if you need to travel a short distance? Even if you have a reasonable public transport facility in the city, it might not cover the route you need to take. Take the example of a large university campus. Such a campus is often at a considerable distance from the central business district of the city where it’s located. While public transport facilities may serve the central business district, they wouldn’t serve this large campus. Currently, many people drive their cars even for short distances.

As you know, that brings its own set of challenges. Vehicular traffic adds significantly to pollution, moreover, finding a parking spot can be hard in crowded urban districts.

Well, you can reduce your carbon footprint if you use an electric car. However, electric cars are still new, and many countries are still building the necessary infrastructure for them. Your large campus might not have the necessary infrastructure for them either. Presently, electric cars don’t represent a viable option in most geographies.

As a result, you need to buy and maintain a car even if your commute is short. In addition to dealing with parking problems, you need to spend significantly on your car.

All of these factors have combined to make people sit up and think seriously about cars. Many people are now seriously considering whether a car is really the best option even if they have to commute only a short distance.

This is where micro-mobility enters the picture. When you commute a short distance regularly, e-scooters or e-bikes are viable options. You limit your carbon footprints and you cut costs!

Businesses have seen this shift in thinking, and e-scooter companies like Lime and Bird have entered this field in a big way. They let you rent e-scooters by the minute. On the other hand, start-ups like Jump and Lyft have entered the e-bike market.

Think of your campus now! The people there might need to travel short distances within the campus, and e-scooters can really help them.

How micro-mobility can benefit you


What advantages can you get from micro-mobility? Let’s take a deeper look into this question.

Micro-mobility can offer several advantages to the people on your campus, e.g.:

  • Affordability: Shared e-scooters are cheaper than other mass transportation options. Remember that the people on your campus will use them on a shared basis, and they will pay for their short commutes only. Well, depending on your operating model, you might even let them use shared e-scooters or e-bikes for free!
  • Convenience: Users don’t need to worry about finding parking spots for shared e-scooters since these are small. They can easily travel from point A to point B on your campus with the help of these e-scooters.
  • Environmentally sustainable: Shared e-scooters reduce the carbon footprint, moreover, they decongest the roads. Statistics from the pilot programs in cities like Portland and Denver showimpressive gains around this key aspect.
  • Safety: This one’s obvious, isn’t it? When people on your campus use small e-scooters or e-bikes instead of cars, the problem of overspeeding will disappear. you will see fewer accidents.

Best Electric Bikes and Scooters for Rental Business or Campus Facility

The electric scooter revolution has caught on super-fast taking many cities across the globe by storm. eScooters, a renovated version of old-school scooters now turned into electric vehicles are an environmentally friendly solution to current on-demand commute problems. They work on engines, like cars, enabling short traveling distances without hassle. The result is that these groundbreaking electric machines can now provide faster transport for less — cheaper than Uber and faster than Metro.

Since they are durable, fast, easy to operate and maintain, and are more convenient to park compared to four-wheelers, the eScooters trend has and continues to spike interest as a promising growth area. Several companies and universities are increasingly setting up shop to provide eScooter services realizing a would-be profitable business model and a ready customer base that is university students or residents in need of faster and cheap travel going about their business in school, town, and other surrounding areas.

Electric Scooters Trends and Statistics

In many countries including the U.S., Canada, Mexico, U.K., Germany, France, China, Japan, India, Brazil and Mexico and more, a growing number of eScooter users both locals and tourists can now be seen effortlessly passing lines of drivers stuck in the endless and unmoving traffic.

A recent report by McKinsey revealed that the E-Scooter industry will be worth― $200 billion to $300 billion in the United States, $100 billion to $150 billion in Europe, and $30 billion to $50 billion in China in 2030. The e-Scooter revenue model will also spike and is projected to rise by more than 20% amounting to approximately $5 billion.

And, with a necessity to move people away from high carbon prints, traffic and congestion issues brought about by car-centric transport systems in cities, more and more city planners are developing more bike/scooter lanes and adopting zero-emission plans. This is the force behind the booming electric scooter market and the numbers will only go higher and higher.

Companies that have taken advantage of the growing eScooter trend develop an appthat allows them to provide efficient eScooter services. Such an app enables them to be able to locate bike pick-up and drop points through fully integrated google maps.

List of Best Electric Bikes for Rental Business or Campus Facility 2020:

It’s clear that e scooters will increasingly become more common and the e-scooter business model will continue to grab the attention of manufacturers, investors, entrepreneurs. All this should go ahead with a quest to know what are some of the best electric bikes in the market especially for anyone who would want to get started in the electric bikes/scooters rental business.

We have done a comprehensive list of the best electric bikes! Each bike has been reviewed in depth and includes a full list of specs and a photo.

How long does it take to develop/build an app?

With more of us using smartphones, the popularity of mobile applications has exploded. In the digital era, the number of people looking for products and services online is growing rapidly. Smartphone owners look for mobile applications that give them quick access to companies’ products and services. As a result, mobile apps provide customers with a lot of benefits in just one device.

Likewise, companies use mobile apps to increase customer loyalty and improve their services. Mobile Developers are in high demand as companies use apps not only to create brand awareness but also to gather information. For that reason, mobile apps are used as tools to collect valuable data from customers to help companies improve their offer.

There are many types of mobile applications, each with its own advantages. For example, native apps perform better, while web apps don’t need to be customized for the platform or operating system (OS). Likewise, hybrid apps provide users with comfortable user experience. However, you may be wondering how long it takes to develop an app.

To give you an idea of how long the app development process takes, here’s a short guide.

App Idea & Research


_Average time spent: two to five weeks _

This is the initial stage and a crucial step in setting the project in the right direction. In this stage, you brainstorm ideas and select the best one. Apart from that, you’ll need to do some research to see if your idea is viable. Remember that coming up with an idea is easy; the hard part is to make it a reality.

All your ideas may seem viable, but you still have to run some tests to keep it as real as possible. For that reason, when Web Developers are building a web app, they analyze the available ideas to see which one is the best match for the targeted audience.

Targeting the right audience is crucial when you are developing an app. It saves time when shaping the app in the right direction as you have a clear set of objectives. Likewise, analyzing how the app affects the market is essential. During the research process, App Developers must gather information about potential competitors and threats. This helps the app owners develop strategies to tackle difficulties that come up after the launch.

The research process can take several weeks, but it determines how successful your app can be. For that reason, you must take your time to know all the weaknesses and strengths of the competitors, possible app strategies, and targeted audience.

The outcomes of this stage are app prototypes and the minimum feasible product.

The Internet Of Things(IoT) is a system that interrelates computer devices like sensors, software, and actuators, digital machines, etc. They are linked together with particular objects that work through the internet and transfer data over devices without humans interference.

Famous examples are Amazon Alexa, Apple SIRI, Interconnected baby monitors, video doorbells, and smart thermostats.

How could your IoT devices be vulnerable?

When technologies grow and evolve, risks are also on the high stakes. Ransomware attacks are on the continuous increase; securing data has become the top priority.

When you think your smart home won’t fudge a thing against cybercriminals, you should also know that they are vulnerable. When cybercriminals access our smart voice speakers like Amazon Alexa or Apple Siri, it becomes easy for them to steal your data.

Cybersecurity report 2020 says popular hacking forums expose 770 million email addresses and 21 million unique passwords, 620 million accounts have been compromised from 16 hacked websites.

The attacks are likely to increase every year. To help you secure your data of IoT devices, here are some best tips you can implement.

Tips to secure your IoT devices

1. Change Default Router Name

Your router has the default name of make and model. When we stick with the manufacturer name, attackers can quickly identify our make and model. So give the router name different from your addresses, without giving away personal information.

2. Know your connected network and connected devices

If your devices are connected to the internet, these connections are vulnerable to cyber attacks when your devices don’t have the proper security. Almost every web interface is equipped with multiple devices, so it’s hard to track the device. But, it’s crucial to stay aware of them.

3. Change default usernames and passwords

When we use the default usernames and passwords, it is attackable. Because the cybercriminals possibly know the default passwords come with IoT devices. So use strong passwords to access our IoT devices.

4. Manage strong, Unique passwords for your IoT devices and accounts

Use strong or unique passwords that are easily assumed, such as ‘123456’ or ‘password1234’ to protect your accounts. Give strong and complex passwords formed by combinations of alphabets, numeric, and not easily bypassed symbols.

Also, change passwords for multiple accounts and change them regularly to avoid attacks. We can also set several attempts to wrong passwords to set locking the account to safeguard from the hackers.

5. Do not use Public WI-FI Networks

Are you try to keep an eye on your IoT devices through your mobile devices in different locations. I recommend you not to use the public WI-FI network to access them. Because they are easily accessible through for everyone, you are still in a hurry to access, use VPN that gives them protection against cyber-attacks, giving them privacy and security features, for example, using Express VPN.

6. Establish firewalls to discover the vulnerabilities

There are software and firewalls like intrusion detection system/intrusion prevention system in the market. This will be useful to screen and analyze the wire traffic of a network. You can identify the security weakness by the firewall scanners within the network structure. Use these firewalls to get rid of unwanted security issues and vulnerabilities.

7. Reconfigure your device settings

Every smart device comes with the insecure default settings, and sometimes we are not able to change these default settings configurations. These conditions need to be assessed and need to reconfigure the default settings.

8. Authenticate the IoT applications

Nowadays, every smart app offers authentication to secure the accounts. There are many types of authentication methods like single-factor authentication, two-step authentication, and multi-factor authentication. Use any one of these to send a one time password (OTP) to verify the user who logs in the smart device to keep our accounts from falling into the wrong hands.

9. Update the device software up to date

Every smart device manufacturer releases updates to fix bugs in their software. These security patches help us to improve our protection of the device. Also, update the software on the smartphone, which we are used to monitoring the IoT devices to avoid vulnerabilities.

10. Track the smartphones and keep them safe

When we connect the smart home to the smartphone and control them via smartphone, you need to keep them safe. If you miss the phone almost, every personal information is at risk to the cybercriminals. But sometimes it happens by accident, makes sure that you can clear all the data remotely.

However, securing smart devices is essential in the world of data. There are still cybercriminals bypassing the securities. So make sure to do the safety measures to avoid our accounts falling out into the wrong hands. I hope these steps will help you all to secure your IoT devices.

Zoom Rolls Out End-to-End Encryption After Setbacks

Video-conferencing giant Zoom is rolling out a technical preview of its end-to-end encryption (E2EE) next week.

Zoom has faced various controversies around its encryption policies over the past year, including several lawsuits alleging that the company falsely told users that it offers full encryption. Then, the platform came under fire in May when it announced that it would indeed offer E2EE — but to paid users only. The company later backtracked after backlash from privacy advocates, who argued that security measures should be available to all. Zoom will now offer the feature to free/”Basic” users.

The first phase of the E2EE rollout aims to solicit feedback when it comes to its policies. Users will be able to weigh in during the first 30 days. Of note, users will need to turn on the feature manually (see below for details).

“We’re pleased to roll out Phase 1 of 4 of our E2EE offering, which provides robust protections to help prevent the interception of decryption keys that could be used to monitor meeting content,” said Max Krohn, head of security engineering with Zoom, in a Wednesday post.

End-To-End Encryption Errors

The topic of encryption is critical for Zoom as it ramps up its security and privacy measures – particularly after various security flaws and privacy issues exposed weaknesses in the online meeting platform, as its user base spiked during the coronavirus pandemic.

Zoom previously said that it offered E2EE, but that marketing claim came into question after a March report from The Intercept said that Zoom’s platform actually uses transport layer security (TLS) encryption, providing only encryption between individual users and service providers, instead of directly between the users of a system.

While “encryption” means that in-transit messages are encrypted, true E2EE occurs when the message is encrypted at the source user’s device, stays encrypted while its routed through servers, and then is decrypted only at the destination user’s device.

On the heels of this backlash, Zoom in May acquired a small startup called Keybase, with the aim of providing more robust encryption for Zoom calls.

In the case of next week’s rollout, Zoom’s E2EE offering will use public-key cryptography, meaning that the keys for each Zoom meeting are generated by participants’ machines (as opposed to Zoom’s servers).
