Secret Sharing

Welcome! You have come to the right place.

If you have a password or a similar important secret, and somebody may need access to it when you are not available, but you don't want to give it to a single person for safekeeping, or put it into the strong box:

Then these pages tell you how to give pieces of the secret for example to five of your friends, so that only if three of your friends put their pieces together, they can reconstruct the secret.

If you are looking for a way to split the password into encrypted pices so that any three pieces can be used to reconstruct the password, the following page is your friend:

=> Sharing Passwords (Three Parts Needed, Easy Math)

If you need more flexibility and do not care about a more involved algorithm (Shamir's Secret Sharing), look here:

=> Securely Sharing Secrets Like Passwords

=> Restoring Shared Secrets Like Passwords

Instead of 'more information', maybe you'd like to see the source code of these pages on GitHub or download the full distribution package of these pages which can simply be unzipped and opened in a browser. It also contains the project's sources (mainly Typescript & HTML).
