gnutls_dh_set_prime_bits - API function
void gnutls_dh_set_prime_bits(gnutls_session_t session, unsigned int bits);
is a gnutls_session_t structure.
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 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.
