Savour Secret repo

dapplink-secret is an implementation of Shamir's threshold secret sharing scheme in JavaScript, for Node.js and browsers with both Global variable and AMD module loading support.

It can be used to split any "secret" (i.e. a password, text file, Bitcoin private key, anything) into n number of "shares" (each the same size in bits as the original secret), requiring that exactly any number t ("threshold") of them be present to reconstruct the original secret.

This is a fork of the original excellent code created by amper5and on Github. The original dapplink-secret can be found there.
