Cryptopals
WebJun 21, 2024 · Encryption is a process of encoding messages such that it can only be read and understood by the intended parties. The process of extracting the original message from an encrypted one is called Decryption. Encryption usually scrambles the original message using a key, called encryption key, that the involved parties agree on. WebIf you want to break or audit existing systems something like Cryptopals is probably the way to start. If you want to make systems, there are other paths, and a few rules to follow. (Don't get discouraged by those rules, they're less daunting than they look. Learn at your own pace, and review those rules as you try to build something for real.)

WebSep 16, 2024 · Cryptopals Rule: Always operate on raw bytes, never on encoded strings. Only use hex and base64 for pretty-printing. I did go ahead and pull in a crate for handling base64 encoding.

WebStep 1: Let’s Stream That (Block) Cipher Here’s info on CTR mode (wikipedia). Notable points: Encryption and decryption both use the AES encryption process on the keystream bytes. All we do to encrypt or decrypt the plaintext/ciphertext is XOR with this encrypted keystream. CTR converts our block cipher into a stream cipher. WebOct 10, 2024 · Cryptopals Rule.
