Comment (by warner):

 Looks like the easy half is done: {{{frontends/auth.py}}} parses the
 pubkey lines from the account file and stashes them in the right place.

 The hard half will involve code from {{{twisted/conch/checkers.py}}},
 probably from {{{SSHPublicKeyDatabase._cbRequestAvatarId}}}, specifically
 this bit:

 {{{
 pubKey = keys.Key.fromString(credentials.blob)
 if pubKey.verify(credentials.signature, credentials.sigData):
     return credentials.username
 }}}

 plus some code to make sure we're using the right key for the requested
 username.
