Subject: Re: [ietf-dkim] Clarification needed for "Computing the
Message Hashes"
You're computing two hashes. The first is a hash over the signed
header fields (which gets stored in the "bh="), and the second is over
the body followed by the (incomplete) DKIM-Signature header field.
Did you write that correctly, Murray? The *body* hash gets stored into
bh. I think you mean
Sorry, yes. That was my pre-coffee answer. It's:
1) Compute the body hash. Store that in "bh=".
2) Compute a hash over all the header fields to be signed, in order, including
the partial DKIM-Signature header field at the end without a trailing CRLF.
3) Encrypt that. Store that in "b=".
