Why is Wire secure?

Wire is a secure messaging app that uses end-to-end encryption (E2EE) for all communications—including messages, calls, and file sharing—ensuring only participants can decrypt the information. E2EE is always enabled by default and cannot be disabled. Wire's open-source code allows anyone to verify its security protocols.

Message Encryption:

Wire employs the Proteus protocol, its implementation of the Axolotl/Double Ratchet protocol, to secure messages between clients. By utilizing pre-keys, Wire allows encrypted conversations to start even when both parties are not online simultaneously. The Proteus protocol incorporates robust cryptographic primitives:  

ChaCha20 Stream Cipher

HMAC-SHA256 for message authentication codes

Curve25519 for elliptic curve Diffie-Hellman key exchange

HKDF for key derivation functions

Media Encryption:

For one-to-one audio and video calls, Wire uses the Secure Real-time Transport Protocol (SRTP), with encryption keys and parameters negotiated through a Datagram Transport Layer Security (DTLS) handshake. Client authenticity is verified via fingerprint exchange over authenticated Proteus sessions. Conference calls are similarly encrypted but leverage Insertable Streams for E2EE of media packets, using: 

AES-GCM 256 for payload encryption

HKDF-SHA512 for key derivation

Forward Secrecy (FS) & Post-Compromise Security (PCS):

Wire ensures that all communications benefit from Forward Secrecy (FS) and Post-Compromise Security (PCS):

Forward Secrecy (FS): Even if an encryption key is compromised, past communications remain secure because each message is encrypted with a unique key.

Post-Compromise Security (PCS): After detecting a security breach and replacing compromised keys, future communications remain secure, safeguarding against attackers who had access to earlier sessions.
