Hi!
We are using only the OpenSSL cryptographic functionality, the EVP and HMAC
functions, in a multi-threaded application. Do we need to do anything to
ensure thread safety ? The documentation mentions
CRYPTO_set_locking_callback() and CRYPTO_set_id_callback() but we are not
calling these functions nor have we put critical sections in our own code
before calling the cryptographic functions. We are experiencing some
crashes and attempting to track them down and thought our use of OpenSSL
may be faulty.
Yes you need to do a few things.
The ORA Network Security with OpenSSL documents the few stubs you need
to in order for openssl to work with pthreads as well as windows
threads. You can even download the example code from the net.
What is the link for the above ?
