The SHA2
*_{Init,Update,Final,Transform}()functions on FreeBSD (manual) and NetBSD (cf manual) collide with functions of the same name in OpenSSL. The signatures are incompatible (return types and contexts).This leads to undesirable runtime failures when using
-fsanitize=-addressin combination with-lcrypto.Not all of the below are problematic for both FreeBSD and NetBSD, but should probably be audited in detail and potentially be removed.
