i have a problem with the encrypt of the bytes with an AES 256 key. I already installed the policy. Here's what I've done:
But still I get an error message with the following code:
KeyGenerator keyGenerator = KeyGenerator.getInstance("AES");
keyGenerator.init(256);
SecretKey secretKey = keyGenerator.generateKey();
Cipher decryption = Cipher.getInstance("AES/CBC/PKCS5PADDING");
decryption.init(Cipher.DECRYPT_MODE, secretKey,
new IvParameterSpec(secretKey.getEncoded())); // <-- Illegal key size
My Java version:
java version "1.7.0_40"
Java(TM) SE Runtime Environment (build 1.7.0_40-b43)
Java HotSpot(TM) 64-Bit Server VM (build 24.0-b56, mixed mode)
What i have to do, to use the 256 AES encryption?
Policy files should resolve the issue. Check the path environment variable to confirm that you are using the same jre which has policy files.
