Hi Alex

The APIs I am using are libssh2_session_hostkey to retreive the host key
and libssh2_hostkey_hash to compute the hash from the key.

The first API returns the length of the host key in a variable passed to it
as a function argument. The variable is of size_t type and indicates the
size of host key. I need to convert this value to bits. Can you let me know
how can I do this?

This variable is passed to the second api and the hash is returned. Here
based on the type of host key, if it is RSA I request for the md5 hash and
sha1 hash for DSS key. Let me know if my assumption is correct here
