ravencoin-message

Sign and verify messages in Ravencoin (and Evrmore) in JavaScript. Works in Node.js and in the browser.

Breaking changes in 1.0.0

sign and verifyMessage now take a single options object instead of positional arguments:

// 0.7.0
sign(message, privateKey)
verifyMessage(message, address, signature)

// 1.0.0
sign({ message, privateKey })
verifyMessage({ message, address, signature })

Optional network ("rvn" or "evr") and prefix can be passed on the same object.

install

npm install @ravenrebels/ravencoin-message

//If you need to sign messages,  install CoinKey
npm install coinkey

How to use

const { sign, verifyMessage } = require("@ravenrebels/ravencoin-message");

//coinkey helps us convert from WIF to privatekey
const CoinKey = require("coinkey");

//Sign
{
  //Address RVDUQTULaceEudDsgqCQBT6bfcdqUSvJPV
  //Public Key 031c5142f11f629bad27dd567c41e189ee23eccd9b57561fd0ff7c96b2cc9a0a0f
  const privateKeyWIF = "L1JHsDosNU9FeUYB24Pixwkxs56pwCrj5rdtuKHXTcWBJTDLGNa7";

  //Convert WIF to private key
  const privateKey = CoinKey.fromWif(privateKeyWIF).privateKey;
  const message = "Hello world";

  // Sign for Ravencoin (default)
  const signature = sign({ message, privateKey });
  console.log("Ravencoin Signature", signature);

  // Sign for Evrmore
  const signatureEvr = sign({ message, privateKey, network: "evr" });
  console.log("Evrmore Signature", signatureEvr);
}

//Verify
{
  const address = "RS4EYELZhxMtDAuyrQimVrcSnaeaLCXeo6";
  const message = "Hello world";
  const signature =
    "H2zo48+tI/KT9eJrHt7PLiEBMaRn1A1Eh49IFu0MbfhAFBxVc0FG2UE5E79PCbhd9KexijsQxYvNM6AsVn9EAEo=";

  console.log("Verify RVN", verifyMessage({ message, address, signature }));
  
  // To verify an Evrmore signature:
  // verifyMessage({ message, address, signature: signatureEvr, network: "EVR" })
}

Supported Networks (Aliases)

The network parameter is case-insensitive and supports the following aliases:

• Ravencoin (Default): "rvn", "ravencoin", "raven"
• Evrmore: "evr", "evrmore"

Advanced: You can also pass a custom prefix string directly to override the network alias.
