Lately I was playing with pass and trying to setup a self hosted service. I don't think it'll work for me, but along the way I ran into an extension for Tomb. Tomb handles encrypted files and it can work with a tool called Steghide. Steghide will let you hide a message in an image and recover it later. Imagine if you had a library of family photos and one of them has your master password buried in it. You could... Source: about 1 year ago

It hasn't been packaged for void yet, but you can try compiling it yourself; source seems to be here. Source: over 1 year ago

A slightly different concept but to "hide" data in other files (images/audio) is steganography or this cool opensource tool called steghide http://steghide.sourceforge.net/ Interestingly if you do it with audio files, tools like my eXtace (extace.sourceforge.net) (a realtime FFT visualizer for sound) will show it quite clearly in the frequency domain whereas it'll be pretty much invisible in the time domain.

Suppose you get along with GPG (The GNU Privacy Guard, GnuPG) for good privacy, and sometimes want to change the passphrase of its secret key. - Source: dev.to / 9 months ago

GnuPG will do this, but both people need to have it set up properly. Source: about 1 year ago

This Docker image is designed to support implementing Github Actions With Python. As of version 4.0.0., it starts with The official python docker image as the base Which is a Debian OS. It specifically uses python:3-slim to keep the image size Down for faster loading of Github Actions that use pyaction. On top of the Base, we've installed curl Gpg, git, and the GitHub CLI. We added curl and gpg because they Are... - Source: dev.to / about 1 year ago

Though FWIW my real answer, if you were asking this as a practical question rather than an educational exercise, would be to find some existing standard encryption program and use that. Something like GPG, perhaps, or even the built-in encryption in your computer's filesystem. It's going to be plenty good enough. Source: about 1 year ago

Https://gnupg.org/ maybe? If you want to encrypt stuff in the cloud, storj is good. Source: about 1 year ago
