Hello,
I've got a question regarding the computing of message hashes. In
chapter 3.7 is listed a formal notation for that algorithm:
body-hash = hash-alg(canon_body)
header-hash = hash-alg(canon_header || DKIM-SIG)
signature = sig-alg(header-hash, key)
I'm not quite sure, what "||" means. I assume it means concatenation
of the two strings. Is that right?
Then it would perhaps be better to write
header-hash = hash-alg(canon_header + DKIM-SIG)
or
header-hash = hash-alg(concat(canon_header,DKIM-SIG))
in the second line or at least to mention concatenation explicitly in the
text.
TIA,
Roman
