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

SYNOPSIS
       #include <libssh2.h>

       const char *
       libssh2_hostkey_hash(LIBSSH2_SESSION *session, int hash_type);

DESCRIPTION
       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).

RETURN VALUE
       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.
