The PID would be the same as the process which opened the session. libssh doesn't fork.

libssh doesn't provide an API to get the pid of the process, it is out of the scope for the library. You should use platform specific API, such as getpid() on Linux.

No, 25519 is not the PID. ssh-ed25519 refers to the key type, in this case EdDSA on Curve25519 curve. See [1].

You were basically "lucky": that is part of the base64-encoded key.
