A standalone addon for GnuPG

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.

Kalyna cipher implementations

A novel symmetric encryption algorithm implemented in Dart

Program that encrypts plaintext and (attempts) to decrypt ciphertexts, encrypted via a mono-alphabetic substitution cipher. Replaces letters based on frequency / n-gram analysis. Tried to incorporate hill-climbing algorithm by measuring the fitness of resulting texts to find the best key.

Self hosted streaming media server written in Rust

Encrypt and decrypt files easily with Rijndael symmetric-key algorithm

Very secure symmetric encryption algorithm with unlimited key length.

Twofish ECB block cipher implementation in pure Java. No dependencies.

Symmetric-key BMP image encryption algorithm.

Creating a login page sending user enter password in encrypted form using Symmetric-Encryption concept

🔐 Fernet guarantees that a message encrypted using it cannot be manipulated or read without the key. Fernet is an implementation of symmetric (also known as “secret key”) authenticated cryptography.

Terminal based password encryption/decryption tool

Poorman's Security Algorithm

Benchmark of block ciphers/Программная система для тестирования быстродействия алгоритмов шифрования

My Cryptosystem - Encrypt and Decrypt Messages - ReactJS + Bulma

This is an symmetric encryption algorithm. It is a more glorified version of a substitution cipher. However, some substitutions are added that do not correspond to a letter to try and confuse anyone trying to break the cipher
