A pure JavaScript implementation of the AES block cipher and all common modes of operation for node.js or web browsers.

Keyshuffling Attack for Persistent Early Code Execution in the Nintendo 3DS Secure Bootchain

Implementations of the Simon and Speck Block Ciphers

A list of VHDL codes implementing cryptographic algorithms

Implementation of PKCS7 padding in C

Tool for generation of data from cryptoprimitives (block and stream ciphers, hash functions). Cryptoprimitives are round-reduced and the data can be configured for multiple testing scenarios.

Automatic problem solver based on circuit-like representation and genetic programming

Simple .NET Core crypto library

AES block cipher modes with the user interface.

python implementation of twofish for 128 bit

A cryptography package with simplifed versions of AES and SHA-1, RSA, HMAC; featuring attacks, block ciphers and digital signature schemes.

Kalyna cipher implementations

PC4 Block cipher encryption for DMR RADIO. Up to 2112-bit keys.

RC6 Block Cipher for Go / Golang

An implementation of the Threefish block cipher entirely in go with no external dependencies.

Self-study in cryptosystems

This is the project for the CSE451 Computer and Networks Security course in the Faculty of Engineering, Ain Shams University. In this project, we implement secure file transfer over FTP. More details in README.

Cryptanalysis of QARMAv2

Some basic encryption and decryption algorithms

This Ruby implementation of DES (Data Encryption Standard) allows users to encrypt and decrypt messages using a symmetric key. DES is a block cipher that works on 64-bit blocks of data and uses a 56-bit key.
