OpenSSH 9.9 release with support for the post-quantum encryption algorithm ML-KEM.
The release of OpenSSH 9.9, an open implementation of the client and server for operation over SSH 2.0 and SFTP protocols, has been announced. Major changes include: Support for the hybrid key exchange algorithm 'mlkem768x25519-sha256' has been added to ssh and sshd. This algorithm is resistant to quantum computer attacks and represents a combination of X25519 ECDH and the ML-KEM (CRYSTALS-Kyber) algorithm, which was recently standardized by the U.S. National Institute of Standards and Technology […]
