Encryption Algorithm

The module implements the basic XTEA block encryption algorithm (`xtea_encrypt`/`xtea_decrypt`) and also provides a higher level `crypt` function which symmetrically encrypts/decrypts a variable length string using XTEA in OFB mode as a key generator. The `crypt` function does not use... Platforms: Windows, Mac, *nix, Python, BSD Solaris

This script shows a very simple keyword encryption algorithm. It produces an encrypted string the same size as the orginal. Not very strong encryption but good enough for lightweight stuff. Works on bytes so could be used for binary streams if converted to and from stri bytes so could be Platforms: Windows, Mac, *nix, Python, BSD Solaris

TinyCrypt is a NEW encryption algorithm, not written by an expert, nor significantly peer-reviewed. For protecting critical data, please consider alternatives until TinyCrypt is proven. That said, if you're just having fun, or have data that is more easily stolen while you're away from your... Platforms: *nix

The ARC4 Text Encryptor allows you to encrypt and decrypt text based data using the ARC4 encryption algorithm. Wikipedia says: - In cryptography, RC4 (also known as ARC4 or ARCFOUR) is the most widely-used software stream cipher and is used in popular protocols such as Secure Sockets Layer (SSL)... Platforms: Windows

TEA Total is a very small 128 bit private key based encryption/decryption system which uses the block variant of TEA (Tiny Encryption Algorithm). TEA is said to be several times faster than DES, as well as being much smaller and possibly more secure. It also isnt encumbered by any patents and... Platforms: *nix

yyyRSA is a simple program to encrypt and decipher messages with the RSA asymetrical encryption algorithm. Alice wants to send Bob a message. Eve can monitor the communication between Alice and Bob. he can read everything they send to each other. Bob creates a key. It will consist of two... Platforms: *nix
