title: AES 256 Encryption/Decryption without IV
body: <p>I'm developing an application that communicates with a DB located on a VPS.
  I need to store an information, encrypted with AES-256, in my DB. </p>
  
  <p>If I'm correct, when I encrypt, there's an IV parameter which is generated and is different for each encryption. However when I decrypt, I don't have this parameter because I only have the key and the encrypted text in the DB. </p>
  
  <p>What can I do to solve this problem?</p>
