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 or
LIBSSH2_HOSTKEY_HASH_SHA1.
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).
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.
