Most interesting with what you came up with, because my MUA saves then
your message as it should be. However, unfortunately the included hash
does not match. :-(
BTW. are you aware that the NaCl crypto library has also a sign function?
It would then require a second key, same as with GnuPG, but maybe also
worth to explore, because you are a programmer.
Here is a sample implementation in Golang, which unfortunately writes
the signature as binary instead of (base64) ASCII.
The computer helps us to solve problems, we did not have without him.
