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/clats97/clatsecure

Clats Encryption Standard (CES) key generator. It includes 3 AES-type key generation algorithms used with python. You can generate cryptographically secure encryption keys in 128, 192, and 256 bit key sizes. This project was peer reviewed by a CompTIA Security+ certified person.
