bentley@openbsd.org da8af83d3f upstream commit
Reduce instances of `` '' in manuals.

troff displays these as typographic quotes, but nroff implementations
almost always print them literally, which rarely has the intended effect
with modern fonts, even in stock xterm.

These uses of `` '' can be replaced either with more semantic alternatives
or with Dq, which prints typographic quotes in a UTF-8 locale (but will
automatically fall back to `` '' in an ASCII locale).

     Implement Elliptic Curve Cryptography modes for key exchange (ECDH) and
     host/user keys (ECDSA) as specified by RFC5656. ECDH and ECDSA offer
     better performance than plain DH and DSA at the same equivalent symmetric
     key length, as well as much shorter keys.

     Only the mandatory sections of RFC5656 are implemented, specifically the
     three REQUIRED curves nistp256, nistp384 and nistp521 and only ECDH and
     ECDSA. Point compression (optional in RFC5656 is NOT implemented).

     Certificate host and user keys using the new ECDSA key types are supported.

     Note that this code has not been tested for interoperability and may be
     subject to change.

     [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.

     Add support for certificate key types for users and hosts.

     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
