Hi,
I'm trying to use an engine to compute the private and public key for RSA.
However the finish method of my implemented structure is never called. I use
SSL_connect() function with ssl_v3
static RSA_METHOD raw_rsa = {
"RAW RSA method",
pub_enc,
pub_dec,
priv_enc,
priv_dec,
NULL,
NULL,
NULL,NULL,
rsa_init, /*init*/
rsa_finish, /*finish*/
0,
NULL,
NULL,
NULL,
NULL
};
I suspected the ssl_cert_dup() function which add a lock for private key:
if (cert->pkeys[i].privatekey != NULL)
{
ret->pkeys[i].privatekey = cert->pkeys[i].privatekey;
CRYPTO_add(&ret->pkeys[i].privatekey->references, 1,
CRYPTO_LOCK_EVP_PKEY);
Indeed, by commenting the last line, I can access to the finish method when
I close my connection. But the saved (using RSA_set_ex_data) are removed
before(RSA_get_ex_data returns NULL).
I'm using openssl_1.0.1e. The same behavior was seen with 1.0.1c
Any suggestions or hint?
Regards
TheMoud
