Given that this ONLY gets called from ssh codepath, I think the
special prefix can just be "key::", and when a new crypto suite
is introduced to sit next to GPG and SSH, presumably the code
structure to support it will be similar to that of ssh's, and it
can also use "key::" prefix for their literal keys. That design
may be cleaner.
Thanks.
