WebJun 24, 2014 · OpenBSD released a new API with a timing-safe bcmp and memcmp. I strongly agree with their strategy of encouraging developers to adopt "safe" APIs, even at a slight performance loss. The strlcpy/strlcat family of functions they pioneered have been immensely helpful against overflows. Data-independent timing routines are extremely … WebWhen we right-clicked the MassEffect.exe in the Binaries map in Mass Effect we clicked troubleshoot compatibility. It said ssleay32.dll is missing. I tried to locate the file and it seems that Origin's root map has ssleay32.dll and so does the x64 submap, so I don't really understand why it's saying it's missing that DLL file.
