Paper OTP

A paper based one time pad encoded message creator. Messages can decoded using only paper and a light source.

This can be used as a way to reveal important passwords, etc. for friends/family, in case something happens to you, by giving each of the two pages to two people you trust. Both pages are needed to decode the message.

Messages are created locally on your machine and not transmitted anywhere. MIT licensed. Source can be found here.
