OpenSSH is a free version of the SSH connectivity tools that technical users of the Internet rely on. Users of telnet, rlogin, and ftp may not realize that their password is transmitted across the Internet unencrypted, but it is. OpenSSH encrypts all traffic (including passwords) to effectively eliminate eavesdropping, connection hijacking, and other attacks. Additionally, OpenSSH provides secure tunneling capabilities and several authentication methods, and supports all SSH protocol versions.
- ssh-keygen(1): Add optional checkpoints for moduli screening
- ssh-add(1): new -k option to load plain keys (skipping certificates)
- sshd(8): Add wildcard support to PermitOpen, allowing things like "PermitOpen localhost:*". bz #1857
- ssh(1): support for cancelling local and remote port forwards via the multiplex socket. Use ssh -O cancel -L
