However I think it would be useful to have the ability to do a
callback-based public key signing too. One goal here would be to permit
private keys in-memory rather than on disk, to facilitate
process-separation between the process knowing the private key and doing
the signing, and the actually libssh2 code.
So I kind of liked your initial API as a "low-level" API. Maybe libssh2
can expose it, and ALSO provide a utility function for performing
agent-style authentication that is simple to use for applications.
Thoughts?
