gnutls_dh_set_prime_bits






gnutls_dh_set_prime_bits − API function

#include<gnutls/gnutls.h>

, unsigned int void
gnutls_dh_set_prime_bits(gnutls_session_t session



gnutls_session_t session
            is a gnutls_session_t type.

unsigned int bits
            is the number of bits

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.
