[PROTOCOL.certkeys auth-options.c auth-options.h auth-rsa.c] [auth2-pubkey.c authfd.c key.c key.h myproposal.h ssh-add.c] [ssh-agent.c ssh-dss.c ssh-keygen.1 ssh-keygen.c ssh-rsa.c] [sshconnect.c sshconnect2.c sshd.c] revised certificate format ssh-{dss,rsa}-cert-v01@openssh.com with the following changes: move the nonce field to the beginning of the certificate where it can better protect against chosen-prefix attacks on the signature hash Rename "constraints" field to "critical options" Add a new non-critical "extensions" field Add a serial number The older format is still support for authentication and cert generation (use "ssh-keygen -t v00 -s ca_key ..." to generate a v00 certificate) 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@

[ssh_config.5 key.h readconf.c readconf.h ssh-keygen.1 ssh-keygen.c key.c sshconnect.c] Introduce SSH Fingerprint ASCII Visualization, a technique inspired by the graphical hash visualization schemes known as "random art", and by Dan Kaminsky's musings on the subject during a BlackOp talk at the 23C3 in Berlin. Scientific publication (original paper): "Hash Visualization: a New Technique to improve Real-World Security", Perrig A. and Song D., 1999, International Workshop on Cryptographic Techniques and E-Commerce (CrypTEC '99) http://sparrow.ece.cmu.edu/~adrian/projects/validation/validation.pdf The algorithm used here is a worm crawling over a discrete plane, leaving a trace (augmenting the field) everywhere it goes. Movement is taken from dgst_raw 2bit-wise. Bumping into walls makes the respective movement vector be ignored for this turn, thus switching to the other color of the chessboard. Graphs are not unambiguous for now, because circles in graphs can be walked in either direction. discussions with several people, help, corrections and ok markus@ djm@
