Created a PR to fix jdtron/twet ability to generate hashes on tweets : https://github.com/jdtron/twet/pull/3.
@email@example.com, actually I was wrong, I had a misunderstanding of how the hash was supposed to work, I though that the hash was created at each tweet to be able to reply to it. But I noticed that actually a hash is created at the reply. (Am I right?) but it can only work if all the twtxt client share the same algorithm. Am I right ?
