Encryption

  • AES — quick note about how AES works
  • AES-GCM and GCM-SIV — two authenticated modes built on AES.
  • Invisible Salamanders — AEAD that authenticates but does not commit: one ciphertext, two keys, two valid plaintexts. With a working proof of concept.
  • ChaCha20-Poly1305 — the cipher, its one-time MAC, and exactly what a repeated nonce costs you: recover rr, forge at will.
