bitcore-message adds support for verifying and signing bitcoin messages in Node.js and web browsers.
See the main bitcore repo for more information.
Getting Started
npm install bsv-message
To sign a message:
var bsv = require('bsv');
var Message = require('bsv-message');
var privateKey = bsv.PrivateKey.fromWIF('cPBn5A4ikZvBTQ8D7NnvHZYCAxzDZ5Z2TSGW2LkyPiLxqYaJPBW4');
var signature = Message('hello, world').sign(privateKey);
To verify a message:
var address = 'n1ZCYg9YXtB5XCZazLxSmPDa8iwJRZHhGx';
var signature = 'H/DIn8uA1scAuKLlCx+/9LnAcJtwQQ0PmcPrJUq90aboLv3fH5fFvY+vmbfOSFEtGarznYli6ShPr9RXwY9UrIY=';
