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.
