[auth-options.c auth-options.h auth.c auth.h auth2-pubkey.c] [key.c servconf.c servconf.h sshd.8 sshd_config.5] add some optional indirection to matching of principal names listed in certificates. Currently, a certificate must include the a user's name to be accepted for authentication. This change adds the ability to specify a list of certificate principal names that are acceptable. When authenticating using a CA trusted through ~/.ssh/authorized_keys, this adds a new principals="name1[,name2,...]" key option. For CAs listed through sshd_config's TrustedCAKeys option, a new config option "AuthorizedPrincipalsFile" specifies a per-user file containing the list of acceptable names. If either option is absent, the current behaviour of requiring the username to appear in principals continues to apply. These options are useful for role accounts, disjoint account namespaces and "user@realm"-style naming policies in certificates. feedback and ok markus@

Add a RevokedKeys option to sshd_config and a @revoked marker to known_hosts to allow keys to me revoked and banned for user or host authentication. feedback and ok markus@

OpenSSH certificate key types are not X.509 certificates, but a much simpler format that encodes a public key, identity information and some validity constraints and signs it with a CA key. CA keys are regular SSH keys. This certificate style avoids the attack surface of X.509 certificates and is very easy to deploy. Certified host keys allow automatic acceptance of new host keys when a CA certificate is marked as sh/known_hosts. see VERIFYING HOST KEYS in ssh(1) for details. Certified user keys allow authentication of users when the signing CA key is marked as trusted in authorized_keys. See "AUTHORIZED_KEYS FILE FORMAT" in sshd(8) for details. Certificates are minted using ssh-keygen(1), documentation is in the "CERTIFICATES" section of that manpage. Documentation on the format of certificates is in the file PROTOCOL.certkeys feedback and ok markus@

[auth.h auth2.c monitor.c monitor.h monitor_wrap.c monitor_wrap.h] [readconf.c readconf.h servconf.c servconf.h ssh2.h ssh_config.5] [sshconnect2.c sshd_config.5 jpake.c jpake.h schnorr.c auth2-jpake.c] [Makefile.in] Add support for an experimental zero-knowledge password authentication method using the J-PAKE protocol described in F. Hao, P. Ryan, "Password Authenticated Key Exchange by Juggling", 16th Workshop on Security Protocols, Cambridge, April 2008. This method allows password-based authentication without exposing the password to the server. Instead, the client and server exchange cryptographic proofs to demonstrate of knowledge of the password while revealing nothing useful to an attacker or compromised endpoint. This is experimental, work-in-progress code and is presently compiled-time disabled (turn on -DJPAKE in Makefile.inc). "just commit it. It isn't too intrusive." deraadt@
