Hash: SHA256
i just upgraded from 0.28 to 1.02. built on freeBSD from source and it
went _smooth_.
line 25 of the man page says:
Count collision bits:
hashcash -w [ options ] [ stamp ... ]
and line 503 of the man page says:
"hashcash -w 1:24:040806:foo::511801694b4cd6b0:1e7297a"
Report the value of the stamp...
this syntax appears to not work, at least form the command line...
$ hashcash -w 1:24:040806:foo::511801694b4cd6b0:1e7297a
enter stamps to check one per line:
also, it seems that "-w" doesn't work with "-c"...?
this version also seems to have problems checking the width of v0 stamps.

-------------------------------------------------
"IDEA's key length is 128 bits - over twice as long as DES.
Assuming that a brute force attack is the most efficient,
it would require 2^128 (10^38) encryptions to recover the
key. Design a chip that can test a billion keys per
second an throw a billion of the them at the problem,
and it will still take 10^13 years - that's longer than
the age of the universe. An array of 10^24 such chips can
find the key in a day, but there aren't enough silicon
atoms in the universe to build such a machine. Now we're
getting somewhere - although I'd keep my eye on the dark
matter debate."
