Implementation of threshold cryptography algorithm also known as Shamir's secret sharing algorithm.
Usage
var tc = require('thresholdcrypto.js');
Key Distribution
tc.keyDist(total, threshold, key, modulus);
Modulus must be greater than or equal to the key for the algorithm to work.
E.G.
var shares = tc.keyDist(5, 3, 123, 250);
console.log(shares);
//[ [ 1, 93 ], [ 2, 155 ], [ 3, 59 ], [ 4, 55 ], [ 5, 143 ] ]
Key Construction
tc.keyConst(shareArray, modulus);
E.G.
var key = tc.keyConst(shares, 250);
console.log(key);
//123
