libssh2_hostkey_hash - return a hash of the remote host's key

session - Session instance as returned by libssh2_session_init_ex(3)hash_type - One of: LIBSSH2_HOSTKEY_HASH_MD5, LIBSSH2_HOSTKEY_HASH_SHA1 or LIBSSH2_HOSTKEY_HASH_SHA256.

       Returns  the  computed  digest  of  the  remote  system's  hostkey.  The length of the returned string is
       hash_type specific (e.g. 16 bytes for MD5, 20 bytes for SHA1, 32 bytes for SHA256).

       libssh2_hostkey_hash - return a hash of the remote host's key

       Computed hostkey hash value, or NULL if the information is not available (either the session has not  yet
       been  started  up,  or  the  requested hash algorithm was not available). The hash consists of raw binary
       bytes, not hex digits, so it is not directly printable.
