I suppose. But my goal was to make a pure Python version. If someone
has access to a C compiler, they might as well compile the standard C
version. Or if they don't have a C compiler, but someone else has
built a command-line binary, passing flags and reading STDIN (as Eric
does) is simple enough in Python--or in any scripting language, for
that matter.
FWIW, the desktop machine on which I permanently archive my email is
OS/2. Sadly, I couldn't find a compiled binary of haschcash (.c) for
that platform. And also unfortunately, I haven't installed GCC and all
its dependencies there either--though I should do that, for lots of
reasons. Psyco works nicely there though.
But on the happy side, I found that the Windows command-line executable
runs perfectly happily under Odin ('pec hashcash.exe <options>'; hmm...
I should try pe2lx.exe for static conversion). I imagine the speed is
pretty much exactly the same as it would be under Windows (Odin isn't
an emulator, it's an API translator; i.e. it's cross-seeded with Wine).
'course, it's a relatively slow machine nowadays, either way (733Mhz
P3). Anyway, I'll rig up hashcash filters for incoming and outgoing
email using that (unless someone compiles a native OS/2 EXE, by
chance).
I also check and write email on my Powerbook, with OSX and using
Mail.app. Anyone know if anyone has figured out how to interface with
Mail.app, it would certainly be nice to get hashcash integration there.
I imagine it must be possible--maybe in Applescript. But I don't have
any idea now how you would go about that.
Yours, David...
