AES Encryption Java Invalid Key length

Question

I am trying to create an AES encryption method, but for some reason I keep getting

java.security.InvalidKeyException: Key length not 128/192/256

Answer 1

For a stronger key strength encryption you would need to download Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files.
