encryption (130)

The tool is designed as a password dictionary attack tool that targets windows authentication via the SMB protocol. It is really a wrapper script around the ‘smbclient’ binary, and as a result is dependent on it for its execution.
aenig4 emulates the Enigma M4 cipher machine used by the U-boot division of the German Navy during World War II. It can be used as well to emulate the Enigma I machine (M1, M2, M3).
Anontwi - is a tool for OAuth2 applications (such as: GNUSocial, Twitter...) that provides different layers of encryption and privacy methods.
BeeCrypt is a cryptography library that contains highly optimized C and assembler implementations of many well-known algorithms including Blowfish, MD5, SHA-1, Diffie-Hellman, and ElGamal. Unlike some other crypto libraries, BeeCrypt is not designed to solve one specific problem, like file encryption, but to be a general purpose toolkit which can be used in a variety of applications. There are also no patent or royalty issues associated with BeeCrypt.
Botan (formerly OpenCL) is a library of cryptographic algorithms. It includes a wide selection of block and stream ciphers, public key algorithms, hash functions, and message authentication codes, plus a high level filter-based interface. The home page has a list of supported algorithms.
BUGS is the Big and Useful Great Security key encryption algorithm and applications. It is easy to use, and includes sample applications and documentation. The cryptography library can also be used with your own programs. Features include:
  • Private key algorithm
  • Dynamic cryptography algorithm
  • Source code can be made public without making the algorithm weak
  • Infinite key lengths
  • Bilateral bits swwapping with various windows
  • Bilateral Pseudo randomly binary operations
  • Random number added to key
  • Random number generator using the ISAAC algorithm
  • Possibility of generating your own RNG seed
  • Five different cryptography levels, for the best possible
  • combination of efficiency and speed
  • Seed and shuffle functions
  • A clear text can be crypted using its own data
  • Two methods of execution: direct disk access or memory cache
  • Strong key generator
CrococryptQuerl (CQuerl) is a web-based open-source file encryption and file exchange tool. If you trust the application service provider which is running CrococryptQuerl, it can be seen as an "anonymous & encrypted safe deposit box for computer files". The user provides a file and password and receives an ID. No plaintext data is stored in CQuerl including filenames. If the user looses the ID or forgets the password, the encrypted file cannot be recovered - even by the service provider.
A simple, fast and secure PHP/AngularJS based single user feed and mail reader, password and bookmark manager. CacoCloud is divided into a RESTful PHP backend storing all data into a SQLite database and an SPA frontend based on AngularJs.
'ccrypt' is a utility for encrypting and decrypting files and streams. It was designed to replace the standard Unix 'crypt' utility, which is notorious for using a very weak encryption algorithm. 'ccrypt' is based on the Rijndael cipher, which is the U.S. government's chosen candidate for the Advanced Encryption Standard (AES). This cipher is believed to provide very strong security. Unlike unix crypt, the algorithm provided by ccrypt is not symmetric (one must specify whether to encrypt or decrypt). Encryption and decryption depend on a user-supplied keyword (key phrase). Keywords can be any number of characters; all characters are significant (although ccrypt internally hashes the key to 256 bits). Longer keywords provide better security, since they are less likely to be discovered by exhaustive search.

GNU cfs-el was a frontend for using CFS (Cryptographic File System) from Emacs. It is now decommissioned, since there are newer crypto file systems.
