Hi,

Has anyone actually worked on those elements? I just tried the HMAC,
and couldn't get it to match my other implementation. On quick browse,
it looks like it's using wrong constant in few places (SHA_BLOCK where
SHA_CBLOCK should be?). Haven't really tried this yet -- will return
to issue next week...
