Crypter

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 https://github.com/HR/Crypter/milestone/4 



    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.
