Cryptography
Perry natively implements password hashing, JWT tokens, and Ethereum cryptography.
bcrypt
import bcrypt from "bcrypt";
const hash = await bcrypt.hash("mypassword", 10);
const match = await bcrypt.compare("mypassword", hash);
console.log(match); // true
Argon2
import argon2 from "argon2";
const hash = await argon2.hash("mypassword");
const valid = await argon2.verify(hash, "mypassword");
console.log(valid); // true
JSON Web Tokens
import jwt from "jsonwebtoken";
const secret = "my-secret-key";
// Sign a token
const token = jwt.sign({ userId: 123, role: "admin" }, secret, {
expiresIn: "1h",
});
// Verify a token
const decoded = jwt.verify(token, secret);
console.log(decoded.userId); // 123
Node.js Crypto
import crypto from "crypto";
// Hash
const hash = crypto.createHash("sha256").update("data").digest("hex");
// HMAC
const hmac = crypto.createHmac("sha256", "secret").update("data").digest("hex");
// Random bytes
const bytes = crypto.randomBytes(32);
Ethers
import { ethers } from "ethers";
// Create a wallet
const wallet = ethers.Wallet.createRandom();
console.log(wallet.address);
// Sign a message
const signature = await wallet.signMessage("Hello, Ethereum!");
