gnutls_dh_get_prime_bits3

Api function

Usage

int gnutls_dh_get_prime_bits(gnutls_session_t session);

Arguments

gnutls_session_t session

is a gnutls session

Overview

This function will return the bits of the prime used in the last Diffie-Hellman key exchange with the peer. Should be used for both anonymous and ephemeral Diffie-Hellman. Note that some ciphers, like RSA and DSA without DHE, do not use a Diffie-Hellman key exchange, and then this function will return 0.

Returns

The Diffie-Hellman bit strength is returned, or 0 if no Diffie-Hellman key exchange was done, or a negative error code on failure.
