encryption (89)



Aesutil 2
'aesutil' is a small library and command line program to encrypt or decrypt data using the Rijndael algorithm in CBC mode.

BeeCrypt
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
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
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

CacoCloud
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
'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.

Cfs-el

Cjdns
Cjdns implements an encrypted IPv6 network using public key cryptography for address allocation and a distributed hash table for routing. This provides near zero-configuration networking without many of the security and robustness issues that regular IPv4 and IPv6 networks have.

Hyperboria is the largest cjdns network, with hundreds of active nodes around the world.

Crackxls2003
This program may be used to break the encryption on Microsoft Excel XP/2002/2003 files which have been encrypted using the RC4 method. These files are encrypted using a 40-bit-long key. It will not work on files encrypted using later versions or versions 8.0 or earlier.

CrocodileNote
Take simple text notes. You can put them into folders to create your own quick, easy and robust file structure.

CrocodileNote supports two modes - plain and encryption. In encryption mode all data is encrypted using password-based encryption (PKCS#5) with AES-256. These are common industry standards and used by, e.g., the famous TrueCrypt disk encryption.

In plain mode you can view and copy folders directly via PC from your internal SD card.

Further features: - Export to ZIP for backup - Linkify notes in case you store e-mail addresses, Internet addresses/URLs or phone numbers - Auto-logout switch for 30 minutes (encryption mode only)
