Morning, 

I'm working with encryption, and posting encrypted data to a web service. This works fine on the simulator, however when posting to a login service on the device, I'm getting an 'Invalid Credentials' error, which I suspect is being caused by the encryption not working right. 

Im using BlockEncryptor, with PKCS5FormatterEngine and a generated InitializationVector. 

BlockEncryptor encryptor = new BlockEncryptor(new PKCS5FormatterEngine(
				new AESCBCEncryptorEngine(new AESKey(
						Base64InputStream.decode(Constants.AES_PRIVATE_KEY)),
						iv)), outputStream);

Can anyone think of a reason why this would work in Sim, but not on device? 

Thanks

I have an update. 

I fixed the IV on both device and Sim and compared the posted strings. All matched apart from 'Email' 

I then tried encrypting email without the @ sign, and they matched! 

Still.. No idea why the device isn't encrypting the @ sign right

Ok, Sorted... 

Erm... Lets just say be careful with Upper/Lower case.. Apparently they produce different ciphertext 

Yeah.. Lets never speak of this again
