Question

I tried running my application on my pc, but I keep getting this thing. Is it possible that I’m missing some libraries?

fabsam.crypto.CryptoException: java.security.InvalidKeyException: No installed provider supports this key: javax.crypto.spec.SecretKeySpec
    at fabsam.crypto.RC4Decoder.decode(RC4Decoder.java:37) ~[bin/:na]

Code:

cipher.init(Cipher.DECRYPT_MODE,
                    new SecretKeySpec(key.getBytes(DEFAULT_CHARSET), ALGORITHM));

Could it be because I’m using RC4 not ARCFOUR in the ALGORITHM variable?
When I try ARCFOUR I get this:

fabsam.crypto.CryptoException: java.security.InvalidKeyException: Illegal key size or default parameters

Okay, the problem is not with the code. On server this runs just fine with no errors. However on my pc it throws me that InvalidKeyException exception. So it’s something with jvm related.. Any ideas?

Edit:
I now see that I’m getting both exceptions. Not at once, but first time the illegal key size and then no installed provider. I’ve the ALGORITHM set to “ARCFOUR” when running my project.

After lot of struggling and searching and everything, I got the right answer.
