Crypto Experiments

This repository contains the source code of various cryptopgrahic experiments I conducted as part of a cryptology course in my Master's studies.

• aes-decrypt: AES-128 PCBC decryption routine.
• multipad: Attempts to break the encryption of XOR (onetime pad) ciphertext that reused the same key multiple times.
• padding-oracle: Attempts to decrypt a ciphertext by abusing the padding validation of a service performing cryptographic operations.
• vigenere: Attempts to break the encryption of ciphertext generated using the Vigenere cipher.
