const value = "passcode@12345";

const encrypt = Encrypt.encryptValue(value, 10);
(await encrypt).getEncryptedValue();

console.log("value - " + value);
console.log("Encrypted value - ", (await encrypt).getEncryptedValue());

const decrypt = Decrypt.decryptValue(value, (await encrypt).getEncryptedValue() + "!");
console.log("Decrypted value - ", (await decrypt).checkIsValid());
};

main();
`

#### Tokenization and Detokenization

const PAN = "1234 4567 9101 2345";
console.log("PAN - ", PAN);

const token = new Tokenize(PAN, { secret: "secret" });
const tokenized = token.getToken();
console.log("Tokenized PAN - ", tokenized);

const detoken = new Detokenize(tokenized, { secret: "secret" });
console.log("Detokenized PAN - ", detoken.getDeToken());
`

#### JWT
