Last year, Digest::SHA changed its interface from accepting bytes into using strings. Perl people are thát focused on supporting unicode strings, that they forget that some operations work on bits and bytes --not strings...

Eventhough Perl has no way to differentiate between strings and bytes in an internal SV,
that does not mean that programs sometimes really care. SHA computations are very sensitive for the smallest bit change, so there should not be any dwimming, no tricks!
