Message Verification and Signing
Bitcore implementation of bitcoin message signing and verification. This is used to cryptographically prove that a certain message was signed by the holder of an address private key.
For more information refer to the bitcore-message-btcp github repo.
Installation
Message Verification and Signing is implemented as a separate module and you must add it to your dependencies:
For node projects:
npm install bitcore-message-btcp --save
For client-side projects:
bower install bitcore-message-btcp --save
Example
To sign a message:
var privateKey = PrivateKey.fromWIF('cPBn5A4ikZvBTQ8D7NnvHZYCAxzDZ5Z2TSGW2LkyPiLxqYaJPBW4');
var signature = Message('hello, world').sign(privateKey);
To verify a message:
var address = 'n1ZCYg9YXtB5XCZazLxSmPDa8iwJRZHhGx';
var signature = 'H/DIn8uA1scAuKLlCx+/9LnAcJtwQQ0PmcPrJUq90aboLv3fH5fFvY+vmbfOSFEtGarznYli6ShPr9RXwY9UrIY=';
var verified = Message('hello, world').verify(address, signature);
