Web1. Cryptography. In this lesson we will cover a few cryptographic concepts along with the related fields of digital forensics and steganography. Cryptography is the process of encoding or decoding messages and data. In this lesson we will learn about cryptography in three broad sections, ciphers, encryption, and hashing.
