What is wif?

The 'wif' npm package is used for encoding and decoding Wallet Import Format (WIF) keys, which are commonly used in cryptocurrency applications. It provides utilities to convert between WIF and private keys, ensuring secure handling of private keys.

What are wif's main functionalities?

Encoding a private key to WIF

This feature allows you to encode a private key into the Wallet Import Format (WIF). The 'encode' function takes the version, private key buffer, and a boolean indicating if the key is compressed.

const wif = require('wif');
const privateKey = Buffer.from('your_private_key_hex', 'hex');
const wifKey = wif.encode(128, privateKey, true);
console.log(wifKey);

Decoding a WIF key to a private key

This feature allows you to decode a WIF key back into its original private key. The 'decode' function returns an object containing the private key buffer and a boolean indicating if the key is compressed.

const wif = require('wif');
const wifKey = 'your_wif_key';
const decoded = wif.decode(wifKey);
console.log(decoded.privateKey.toString('hex'));
console.log(decoded.compressed);
