Peer RSA/DSA parameters used in handshake may be printed
for example with code:
EVP_PKEY *pkey;
X509 *cert;
cert = SSL_get_peer_certificate(ssl);
if ((cert != NULL) && ((pkey = X509_get_pubkey(cert)) != NULL)) {
if (pkey->type == EVP_PKEY_RSA && pkey->pkey.rsa != NULL
&& pkey->pkey.rsa->n != NULL) {
printf("RSA-%d\n", BN_num_bits(pkey->pkey.rsa->n));
}
if (pkey->type == EVP_PKEY_DSA && pkey->pkey.dsa != NULL
&& pkey->pkey.dsa->p != NULL) {
printf("DSA-%d\n", BN_num_bits(pkey->pkey.dsa->p));
}
}
if (cert != NULL) {
X509_free(cert);
}
