Description

The hashcash tool allows you to create hashcash stamps to attach to emails you send, and to verify hashcash stamps attached to emails you receive. Email senders attach hashcash stamps with the X-Hashcash: header. 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.
