Can't get AES to work

Question

Hey all,
I just registered here in an attempt to fix my problem... I've tried everything I can think of.
My problem seems simple. I do this:
SecretKeySpec keyspec = new SecretKeySpec(key, "AES");
SecretKeyFactory factory = SecretKeyFactory.getInstance("AES");
SecretKey secretkey = factory.generateSecret(keyspec);
Cipher aes = Cipher.getInstance("AES");
aes.init(Cipher.DECRYPT_MODE, secretkey);
return aes.doFinal(data);
And I get this:
java.security.NoSuchAlgorithmException: Algorithm AES not available
at javax.crypto.SunJCE_b.a(DashoA12275)
at javax.crypto.SecretKeyFactory.getInstance(DashoA12275)
at system.Decryptor.decrypt(Decryptor.java:78)
at system.Decryptor.<init>(Decryptor.java:43)
This is at the 'SecretKeyFactory.getInstance("AES");' line. When removed, the 'Cipher.getInstance("AES");' line complains about the same thing ("No support for AES").
In order to remedy this problem I've tried the following:
- Installing Java 1.4.2_09 (I had 1.4.2_05)
- Installing Java 5.0 Update 4 and using that instead
- Using the Bouncy Castle Provider
- Using the Cryptix JCE Provider
- Installing the unlimited strength policy files
- Not using Eclipse
- Forcing the SunJCE Provider (result in "no such algorithm: AES for provider SunJCE")
- Using DES (same error messages, only for DES!)
- Rebooting (I just didn't know anymore :P)
Short from reinstalling Windows 2000 I can't think of anything else. I googled for two nights trying to find people with the same problem but it appears I'm pretty unique... none of the fixes I found worked. I'm pretty sure it must be something related to my set up, since by all means, it should work.
Does anyone have any idea what I can do to fix it? Thanks in advance for any of your help!

hi there,
I just read your posts and apperently I have the same problem.
I get an error message: "Algorithm AES not available"
the thing is this: on my computer (XP) everything works fine! the encryption AES is working (I also able to decrypt)!!! but when I try the SAME code on a different computer (MS2003) it generates the error: "Algorithm AES not available"
is there any file I should add so it will work?
thanks for any help
