Decrypting Encrypted Information

The field of cryptography is the science of encrypting or hiding information. It involves both encryption, the process of encoding a message so that only those with the right key can access it, and steganography, the process of hiding a message within other data. With encryption, we know a message is there; we just can't access it because it is encrypted. With steganography, on the other hand, we are not even aware there is a message. This course introduces learners interested in becoming cybercrime investigators to the science of both decrypting messages and breaking codes and ciphers and reinforces the value to all learners of taking steps to encrypt or hide personal information and other data from cybercriminals.
