Note that libssh2's API still requires you to pass on both the private and the
public keys, so you must have both in the correct format.

But it would help if you'd show us the exact little example source code you're
running when you get your problem, and tell us what return code/error the
libssh2 function that fails returns etc. Possibly also show us what a trace
output log reveals.

That certainly seems like a bad algorithm and an indication of a problem. It
indicates the file is bad I'd say. Or perhaps a bug in libssh2.

There's no point in using any other libssh2 version than the most recent one.
