Hi Adam You should be aware that for the Debian package, in the hashcash manpage, I removed references to sha1sum-hashcash (whoops, looks like I also removed sha1sum, I'll re-add) because Debian already includes sha1sum in one of its base packages, so it is not needed. The exact patch that I had applied is: *************** *** 47,55 **** A hashcash stamp constitutes a proof-of-work which takes a parameterizable amount of work to compute for the sender. The - recipient can verify received stamps efficiently. This package also - includes a sha1 implementation which behaves somewhat like md5sum, but - with SHA1. The hashcash proof-of-work function is to compute partial hash collisions (the SHA1 hash function is used). By choosing the number --- 47,53 ---- A hashcash stamp constitutes a proof-of-work which takes a parameterizable amount of work to compute for the sender.
