// Encrypted keystore JSON (typically stored in a file or database)
const encryptedJson = `{
  "address": "742d35cc6634c0532925a3b844bc9e7595f0ab42",
  "crypto": {
    "cipher": "aes-128-ctr",
    "ciphertext": "...",
    "kdf": "scrypt",
    ...
  }
}`;

  encryptedJson,
  "mySecurePassword123"

console.log(`Decrypted wallet: ${wallet.address}`);

​
Load from File

import fs from "fs";

// Read keystore file
const keystorePath = "./keystore/wallet.json";
const encryptedJson = fs.readFileSync(keystorePath, "utf8");

// Decrypt with password
const wallet = await align.blockchain.wallets.createFromEncrypted(
  encryptedJson,
  process.env.WALLET_PASSWORD!
);

​
Encryption/Decryption Flow

Decryption can take several seconds as it’s intentionally slow (using scrypt) to prevent brute-force attacks.
