Manually shutdown the library

Dan Heinz

The original issue was discussed here:  https://www.mail-archive.com/openssl-users@.../msg80781.html

 

To summarize: We have a DLL that statically links OpenSSL.  Our DLL gets loaded and unloaded multiple times by a process (not our process), and we need to release OpenSSL each time.  This was not possible with OpenSSL 1.1 as of October 2016 as the process’s atexit is where it gets released which will not be called after a FreeLibrary() call on our DLL.  Has this been revisited?  If there is still not a way to manually release OpenSSL, are there any plans to add this ability?

From the previous post, something like this would address the issue:

“I'm wondering whether an option to override the default behaviour might

be possible, e.g. an explicit call to OPENSSL_init_crypto() with

something like an OPENSSL_INIT_NO_ATEXIT_CLEANUP option. The application

would then have to call OPENSSL_cleanup() explicitly.”

There are no plans to do so.  You’ll have to modify the source and/or make a pull request.
