Challenge 16 - Set 2 of the Cryptopals Crypto Challenges. The goal is to modify a ciphertext to change our role to 'admin' and gain some cool privileges.

Challenge 14 - Set 2 of the Cryptopals Crypto Challenges. The goal is to decrypt some target bytes with an oracle function but not much control. This challenge has a lot of similarities with Challenge 12 but there is a twist. I made lots of cool diagrams in this write-up, go check them out!

Challenge 13 - Set 2 of the Cryptopals Crypto Challenges. The goal is to modify a ciphertext to elevate our privileges.

Challenge 12 - Set 2 of the Cryptopals Crypto Challenges. The goal is to decrypt a ciphertext without the key thanks to an oracle.

Challenge 8 - Set 1 of the Cryptopals Crypto Challenges. Given a bunch of hex-encoded ciphertexts, find the one that was encrypted with AES ECB.
