The SHA2 `*_{Init,Update,Final,Transform}()` functions on FreeBSD ([manual][1]) and NetBSD (cf [manual][2]) collide with functions of the same name [in OpenSSL][3]. The signatures are incompatible (return types and contexts).
This leads to undesirable runtime failures when using `-fsanitize=-address` in 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.
