How can I securely store user data in a cryptocurrency exchange database?

#cryptocurrency #securelystore #database #cryptocurrencyexchange

Use PostgreSQL with encrypted data storage:

CREATE TABLE users (
  id SERIAL PRIMARY KEY,
  email VARCHAR(255) NOT NULL UNIQUE,
  password_hash TEXT NOT NULL,
  created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
);

In your Node.js code, hash passwords using bcrypt:

const bcrypt = require('bcrypt');

async function hashPassword(password) {
  const salt = await bcrypt.genSalt(10);
  const hash = await bcrypt.hash(password, salt);
  return hash;
}

async function verifyPassword(inputPassword, storedHash) {
  return await bcrypt.compare(inputPassword, storedHash);
}
