Online Privacy MattersRely on existing, well established Protocols.
Uses a Double Ratchet to establish secure sessions between every combination of devices for you and your contacts. With OMEMO you no longer trust user identities but device identities. If you are communicating with a contact, you will be presented with a fingerprint for that device to identify.
Off-the-Record Messaging is a combination of AES symmetric-key algorithm with 128 bits key length, the Diffie–Hellman key exchange with 1536 bits group size, and the SHA-1 hash function. In addition to authentication & encryption, also forward secrecy & malleable encryption.
Helps you communicate more privately and securely. It uses encryption to ensure that your messages can be read only by the people you send them to, others can send you messages that only you can read, and these messages can be digitally signed so the people getting them are sure who sent them.
