hhmmm... what if the padding was done internally? instead of padding the
stamp that's output, a minting application would create a stamp _as_if_ it
were padded and a verifying application would internally add appropriate
padding before calculating the hash.


Yes I thought about this one also.  However the downside is one can no
longer easily verifying a stamp in script languages using the sha1sum
utility.  One first would have to undeo the padding compression.

=================

the ease (or difficulty) depends on the language and how the padding is handled. padding doesn't have to prepend the counter, it could prepend or append the entire stamp. in any case, awk can handle it with little difficulty and i suspect perl can handle it too.

but if anyone is using a scripting language, they should have a hashcash executable available to do this grunt work.
