I'm running into some trouble loading a key into a cipher to encrypt some strings. Below is the line of code that's causing an issue.
Cipher cipher = Cipher.getInstance("AES");
where secretKey contains 256 bytes.
I'm getting a java.security.InvalidKeyException: Illegal key size or default parameters.
I've scoured the internet and have come to believe this is an environment issue - I'm assuming I need to install JCE (Java Cryptography Extensions), but am running out of luck getting anything to work (most of the better documentation are around 8 years old).
I'll start off by saying I have Eclipse Standard/SDK installed, Version Kepler Service Release 1. Are there any set up gurus out there that could assist me in resolving this issue?
