Some of the programs that were created for practicals in college

A simple project to allow a user to encrypt a message with different types of simple ciphers.

In cryptography, a substitution cipher is a method of encrypting in which units of plaintext are replaced with the ciphertext, in a defined manner, with the help of a key; the "units" may be single letters (the most common), pairs of letters, triplets of letters, mixtures of the above, and so forth.

An implementation of a substitution-permutation-network and a randomized counter CTR

A simple substitution cipher algorithm. Uses characters tables to generate the hash.
