Installation
npm install nacl-signature
Usage
Signing messages:
const signer = ; // base64 encoded secret keyconst secretKey = 'AUBsLQhpSElD5LpLPB1p5JfwYHRIWjrsL+jJkHpBzyt+a1zqQLnX2ovt3czYD3TLU8MBE8MzEkhETP/H6y2ETA==';// base64 encoded public keyconst publicKey = 'fmtc6kC519qL7d3M2A90y1PDARPDMxJIREz/x+sthEw='; // base64 encoded message signatureconst signature = signer;
Verifying signatures:
// verifying a message, given its signature and the sender public keyif signer console;
Note: In production, remember that your "secret key" is secret!
