Default key size

[Stephen ODonnell]

Hi all,

Does anyone know what is the default key size for AES in the following code:

keyGen = KeyGenerator.getInstance("AES");
keyGen.init(new SecureRandom());

I read that AES can have a key size of 128, 192 or 256. What does SecureRandom do?

Any help greatly appreciated,
Thanks,
Stephen

Hi,

I have found that the Default key size for AES is 128, but I can't seem to find the default padding. Can anyone help me with this?

Thanks,
Stephen.
