NAME         top

       gnutls_dh_set_prime_bits - API function

SYNOPSIS         top

       #include <gnutls/gnutls.h>

       void gnutls_dh_set_prime_bits(gnutls_session_t session, unsigned
       int bits);

ARGUMENTS         top

       gnutls_session_t session
                   is a gnutls_session_t type.

       unsigned int bits
                   is the number of bits

DESCRIPTION         top

       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.
