Decrypting error : “no iv set when one expected”

Question

I\'m almost new to encryption.

I am trying to decrypt an array of bytes, and when I am providing the IV I am getting an exception : InvalidAlgorithmParameterExceptio

Answer 1

Solved.

I was using a wrong SecretKey, not the one you can create for AES.

Previously I had :

KeySpec spec = new PBEKeySpec(password.toCharArray(), encryptionKeySalt, 12345,256);
SecretKey encriptionKey = factory.generateSecret(spec);

which creates a JCEPBEKey.

I was missing :

Key encriptionKey = new SecretKeySpec(encriptionKey.getEncoded(), "AES"); 

which creates an appropiate key for AES.
