Az iMessage vagy a Signal nevű app van jobban titkosítva?

Signal:

[link]

Signal instant messages are encrypted with the Signal Protocol (formerly known as the Axolotl protocol[51]). The protocol combines the Double Ratchet Algorithm, prekeys, and a 3-DH handshake.[52] It uses Curve25519, AES-256, and HMAC-SHA256 as primitives.[53] The protocol provides confidentiality, integrity, authentication, participant consistency, destination validation, forward secrecy, backward secrecy (aka future secrecy), causality preservation, message unlinkability, message repudiation, participation repudiation, and asynchronicity

Itt is azt mondjak hogy az iMessage 128 bites. Szoval gyengebb mint a 256-os Signal.
