Secret sharing pads are a simple, computer-free way to securely share passwords with trusted friends and family for use in emergencies.
When you encrypt your passwords using secret sharing pads, the encrypted password is split amongst several printed pads using a technique called secret sharing. On their own the pads cannot be decrypted but, when any two pads are used together, the secret information can be decrypted using just a pen and paper.
This repository contains a simple browser-based tool for creating sets of secret sharing pads to print out.
This software (and its dependencies) can be built using NPM as follows:
$ npm install
$ npm run test
$ npm run build
The resulting assets will be written to the dist/ directory and may be used
directly from your file system (ensuring it cannot exfiltrate your secrets) or
hosted on the web.
This software was not built or devised by a person with specialist experience. It is also a bit scruffy internally. Use it at your own risk!
