All,

Maybe I've missed something, in which case, shoot me down, but why unlike 
other services that make use of public key cryptography, does OpenSSH not 
have use a model which supports proper authorisation and revocation 
mechanisms?  Would this not be an ideal opportunity to implement this?  
Whilst I think there was a reasonable case for such features prior to the 
Debian OpenSSL vulnerability being identified, I would argue that this issue 
highlights the case.  Comercial SSH already has such functionality - can 
anyone offer a view on how [well] it works?
