Hi guys, Tor has its own hand-rolled timing-safe memcmp() which is nice, but Operating Systems like OpenBSD, NetBSD, and possibly others soon are starting to ship with a timing safe memcmp(). On OpenBSD, it's called timingsafe_memcmp(). Below is a patch that checks for it, and uses it if the host platform has a timingsafe_memcmp(). **Trac**: **Username**: logan
