Variable size symmetric key encryption algorithm. PHP & JavaScript implementation, small, portable and fast.

A Lightweight high-performance symmetric encryption framework designed to provide Full Diffusion

Simplified Data Encryption Standard (S-DES) is a simple version of the DES Algorithm. It is a block cipher that takes a block of plain text and converts it into ciphertext. It takes a block of 8 bit. It is a symmetric key cipher, they use the same key for both encryption and decryption. We take a random 10-bit key and produce two 8-bit keys.

Program where people can send messages securely to each other.

dual, double, cascaded, chained symmetric encryption based on either GPG or OpenSSL

A novel symmetric encryption algorithm implemented in Dart

Very simple library based on FramedTCP that provides a fairly secure ecnrypted TCP connection.

This package provides an easy way to encrypt strings into MD5, SHA1, SHA256, SHA384, SHA512, AES, DES, TripleDES, and RC2 formats. It also provides a way to create your own custom cipher and use it to encrypt strings.
