we are using MODP Group 14 RFC-3526 in our SSL Setup, there is a security requirement "Private DH exponent length for key exchange must be minimum 256 bit"

how we know which Private DH Exponent length is in use?

DH key is generetad as follows

DH* dh = DH_new();
DH_set0_pqg(dh, BN_get_rfc3526_prime_2048, NULL, DH_GENERATOR_2)

and DH key is returned by tmp_dh_callback
