Signal Protocol
An open-source encrypted communications protocol developed by the Signal Foundation. It combines message authentication codes, hash chains, and digital signatures to provide end-to-end encryption for instant messaging.
Timeline (last 90 days)
Signal's encryption protocol (Signal Protocol) makes extensive use of mechanisms such as MACs, hash chains, and digital signatures at the transport layer.
Common approaches to implementing E2EE include deriving keys from passwords (such as PBKDF2 or Argon2) followed by AES-256-GCM encryption, or using Signal Protocol's Double Ratchet Algorithm.
