gnutls_dh_set_prime_bits(3)		      gnutls		      gnutls_dh_set_prime_bits(3)

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 structure.

       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 values lower than 512 bits may allow decryption of the exchanged data.

       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_prior-
       ity_set_direct() or the set value may be overridden by the selected priority options.
