A standalone addon for GnuPG

Kalyna cipher implementations

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.

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.

Very secure symmetric encryption algorithm with unlimited key length.

Self hosted streaming media server written in Rust

Encrypt and decrypt files easily with Rijndael symmetric-key algorithm

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.

Poorman's Security Algorithm

Terminal based password encryption/decryption tool

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
