📝§ 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
