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.
