Hi Guix, My problem looks like this. I wrote a simple song about Guix. I would like to send it to all for checking, for correction, for testing... but encrypted. I would not like to send it unencrypted, so that somebody may misuse it during the sending. It includes a pdf, flac, ly, mkv, mp4, wav, ogg file. So what can I do?
