Cryptography is the science of encryption and decryption or more simply the study of how to code a message and decide it. Believe it or not, it’s a lot of math. There are tons of techniques and encoding methods, some thousands of years old. However, I’ll admit a lot of the specifics are above my head.

If you’re curious in some famous cryptography this video on the WWII German enigma code is an excellent way to get the idea of how modern encryption works. https://youtu.be/G2_Q9FoD-oQ
