@harmony-js/crypto
This package provides a collection of apis related to address management, kestore, encoding, and encrypt/decrypt.
Installation
npm install @harmony-js/crypto
Usage
const {
encode,
decode,
randomBytes,
toBech32,
fromBech32,
HarmonyAddress,
generatePrivateKey,
getPubkeyFromPrivateKey,
getAddressFromPublicKey,
getAddressFromPrivateKey,
encryptPhrase,
decryptPhrase
} = require('@harmony-js/crypto');
const { isPrivateKey, isAddress, isPublicKey } = require('@harmony-js/utils');
Address apis
const bytes = randomBytes(20);
const addr = new HarmonyAddress(bytes);
console.log(addr.checksum);
console.log(addr.bech32);
console.log(HarmonyAddress.isValidBech32(addr.bech32));
RLP apis
const encoded = '0x89010101010101010101';
const decoded = '0x010101010101010101';
console.log(encode(decoded));
console.log(decode(encoded));
Keystore apis
const prv = generatePrivateKey();
const pub = getPubkeyFromPrivateKey(prv);
const addr = getAddressFromPublicKey(pub);
const addrPrv = getAddressFromPrivateKey(prv);
console.log(isPrivateKey(prv));
console.log(isPublicKey(pub));
console.log(isAddress(addr));
console.log(isAddress(addrPrv));
Encrypt/decrypt apis
const { Wallet } = require('@harmony-js/account');
const myPhrase = new Wallet().newMnemonic();
console.log(myPhrase);
const pwd = '1234';
encryptPhrase(myPhrase, pwd).then((value) => {
console.log(value);
decryptPhrase(JSON.parse(value), pwd).then(value => {
console.log(value);
});
});
