title: Alternative to Fernet Encyption Algorithm w.o Salt
body: <p>Hi I am new to encryption algorithms and am a little confused by the terminology and what to choose for which situation. For now I don't need the most secure algorithm but it should have the following properties:</p>
  <ul>
  <li>A shared secret key, that encrypts/decrypts the message (two way).</li>
  <li>The Cipher should be the same if same text for encryption has been used.</li>
  </ul>
  <p>I used the Fernet algorithm in Python, however the Ciphertext is always different. and therefore not suitable for my needs. Is there an algorithm similar to Fernet but without the Salt?</p>
