To be concise, a cipher described in the above context refers to the field of cryptography. Cryptography as applied to the control system is the practice and technique for securing data communications ...

"So this was not classified," President Donald Trump said at the White House this week. He was talking about an incident where a journalist was accidentally added to a group chat discussing ...

The AES-C core from Alma Technologies implements the FIPS-197 Advanced Encryption Standard. It can be programmed to encrypt or decrypt 128-bit blocks of data, using 128-, 192-, or 256-bit cipher-key.

Objectives I selected three ciphers: RSA, Hill Cipher and Substitution Cipher. In the case of RSA, I implemented the ability to vary the size of the primes used to create the public (and private) ...

Testing algorithm with different key values. ALGORITHM DESCRIPTION: The Hill cipher is a substitution cipher invented by Lester S. Hill in 1929. Each letter is represented by a number modulo 26. To ...

Simple and beginner-friendly implementations of classic cryptographic algorithms like Playfair, Hill Cipher, DES, AES, RSA, DSA, MD5, SHA512 — using Python. Designed for easy understanding, minimal ...
