Realize your server attempts to call this native several times, and you are creating too many threads at once (again this can crash your application)

I decided to test this by calling bcrypt_hash (work factor 12) 400 times with a for loop. The server did not crash and calculated the hash for each call. It might be that the server crashes if even more concurrent threads are created, but I really doubt that's going to happen under normal circumstances.


Edit: As to the issue with thread safety, what would you recommend as a solution? Based on quick research, the use of mutexes seems promising.
