You have reached the first checkpoint in the 'Journey to cryptography' series.

Vigener cipher. And in fact, decryption is just as easy as encryption.

So in a symmetric encryption system, basically, the two parties,

The decryption key performs the inverse or undo operation, which was applied by the encryption key.

Welcome to Applied Cryptography.

In this class we're going to learn about some of the foundations of cryptography and we're also going to learn to use cryptography to solve problems in computing,
