Const encryptedSecretkey = ‘your_encrypted_secret_key_here’;
// Generate and Random Salt
Const Salt = crypto.randombytes (16) .Tostring (‘hex’);
// Encrypt the User Input String Using The Secret Key and Salt
constherinput = ‘my_user_input’;
constryptedinput = crypto.symmetricencrypt (Inputuser, EncryptedSecretkey, Salt);
Console.log (Encrypted Input: $ {Encryptedinput});
`
The use of the Secret key and salt, and print out the resulting encrypted input.
