📝§ Cryptography

Algorithms

Encryption:
- Block cipher mode of operation
Message Authentication Code (MAC)
- HMAC — Hash-based Message Authentication Code
- GMAC — Message Authentication Code using Galois/Counter Mode
Key Derivation Function (KDF)
- HKDF — HMAC-based Key Derivation Function

Attacks

Length extension attack — an attack on hashing function that allows computing a valid hash for a longer message without knowing the message itself.
TLS CBC IV attack — an attack on CBC cipher when ciphertext of the previous block is reused as IV of the next block.
Replay attack
Key Compromise Impersonation attack
Non-committing AEAD weakness
