NAME

       gnutls_dh_set_prime_bits - API function

SYNOPSIS

       #include <gnutls/gnutls.h>

       void gnutls_dh_set_prime_bits(gnutls_session_t session, unsigned int bits);

ARGUMENTS

       gnutls_session_t session
                   is a gnutls_session_t type.

       unsigned int bits
                   is the number of bits

DESCRIPTION

       This  function sets the number of bits, for use in a Diffie-Hellman key exchange.  This is
       used both in DH ephemeral and DH anonymous cipher suites.  This will set the minimum  size
       of the prime that will be used for the handshake.

       In the client side it sets the minimum accepted number of bits.  If a server sends a prime
       with less bits than that GNUTLS_E_DH_PRIME_UNACCEPTABLE will be returned by the handshake.

       Note that this function will warn via the audit log for value  that  are  believed  to  be
       weak.

       The function has no effect in server side.

       Note  that  since  3.1.7 this function is deprecated. The minimum number of bits is set by
       the   priority   string   level.    Also   this   function   must    be    called    after
       gnutls_priority_set_direct()  or  the set value may be overridden by the selected priority
       options.
