Cryptography

Cryptography, or cryptology is the practice and study of techniques for secure communication in the presence of adversarial behavior. More generally, cryptography is about constructing and analyzing protocols that prevent third parties or the public from reading private messages.

https://github.com/cepdnaclk/e16-4yp-implementation-of-lightweight-cryptographic-algorithms

This project aims to implement and analyse NIST Lightweight cryptography competition finalist algorithms. Lightweight cryptographic algorithms are designed to be run on resource-constrained IoT devices.

https://github.com/levongh/md5

The MD5 algorithm is a widely used hash function producing a 128-bit hash value. Although MD5 was initially designed to be used as a cryptographic hash function, it has been found to suffer from extensive vulnerabilities. It can still be used as a checksum to verify data integrity, but only against unintentional corruption.
