noun | krip·taw·gruh·fee
Cryptography is like the black magic of the internet - it's what keeps your darkest secrets and most shameful browser histories safe from prying eyes. It's a mysterious art that involves a lot of math, a lot of jargon, and a lot of nerds arguing about the best way to encrypt a dick pic.
Example
"Cryptography is like a chastity belt for your data - it keeps everything locked up tight and makes sure no one can get in without your permission (or a really big pair of bolt cutters)."
"I once used cryptography to encrypt a love letter to my ex-girlfriend. Then I realized I forgot the decryption key and now I'll never know what I wrote. Probably for the best, tbh."
