Thanks for sharing that.
Couple of questions: Is the SHA computed over the header or the entirety of the
message? If it's just over the header, then all you'd need is:
$dkim->PRINT($entity->head()->as_string());
right? But then if it were just over the header, you could replay the header so
there wouldn't be much point to that…
If it's over the entirety of the message, then you could do:
$dkim->PRINT($entity->as_string());
for the entire serialized message, yes?
Also, looking at:
chomp;
s/\015$//;
makes me wonder about this (and I've seen it elsewhere). Why not just do:
local $/ = "\r\n";
chomp;
instead?
Thanks,
