Hi Adam (and developers),
Do you have a web page for this implementation?
I want to replace David McNab's implementation with yours.
I put up a copy which I can update to your page when you make one:
http://www.hashcash.org/ -> libs -> python
I banged away at my implementation for a few more hours last night. I
didn't hear anything back about errors, but I tweaked it for about 30%
speedup (i.e. still MANY times slower than the Altivec C version); and
also added some more documentation and a command-line execution
capability with options roughly matching the C hashcash module.
The permanent URL for the module will be:
http://www.gnosis.cx/download/gnosis/util/hashcash.py
I will also incorporate my hashcash.py into my Gnosis Utilities, which
lives at http://gnosis.cx/download/Gnosis_Utils-current.tar.gz. But
that has not happened yet; and there is certainly no requirement for
someone who just wants hashcash to use my whole package. In any case,
the relative location will be the same in the package as it is from the
"live URL" for the module (you'd just use 'from gnosis.util import
hashcash' or the like if you grabbed the whole package).
Anyway, the version I just uploaded is still roughly alpha... but let's
call it a pretty good alpha :-). I'm certainly more than happy to
improve it with suggestions.
Yours, David...
