Well, the issue with password is the symmetric scheme. Assymmetric would be
much better and you could spread your public key around... That could make a
good POC actually... food for tought I guess, like I didn't had enough
projects already lol.

Well, this will trigger a revolution that's for sure. The side abou
addressing the confidentiality and non-repudiation is intersting too. I will
read a little bit about that, this is something I am not familiar enough.

Not very well that's for sure. The lack of compatibility with modern
computing equipment makes it a challenge in itself. I have some good stories
about old technology seen by younger folks. But this is drifting from the
original topic, it's more obfuscation than encryption at that point...
