 <sup>2</sup> Post-quantum cryptography is available in beta version, as opt-in only for direct conversations. See below how it will be rolled-out further.
 
 Some columns are marked with a yellow checkmark:
-- when messages are padded, but not to a fixed size.
+- when messages are padded, but not to a fixed size (Briar pads messages to the size rounded up to 1024 bytes, Signal - to 160 bytes).
 - when repudiation does not include client-server connection. In case of Cwtch it appears that the presence of cryptographic signatures compromises repudiation (deniability), but it needs to be clarified.
 - when 2-factor key exchange is optional (via security code verification).
 - when post-quantum cryptography is only added to the initial key agreement and does not protect break-in recovery.
