As I said, there are standards in cryptography, standard cryptographic primitives which we're gonna discuss at length during this course.

Again, we'll talk about the advanced encryption standards in much more detail

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

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

And primarily you're supposed to use these standard cryptographic primitives, and not invent things, these primitives, yourself.

The decoding machine, Lektor.

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,

Now, they're gonna use a cipher which consists of these two algorithms, E and D. E is called an encryption algorithm and D is called the decryption algorithm.
