     [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)
