Re: Why does this not work?

I can't offer an answer for you, but I have some idea of what you
should probably look into, to find your error. The api for the
Cipher class has 3 getInstance(...) methods.

public static final Cipher getInstance(String transformation)
throws NoSuchAlgorithmException,
NoSuchPaddingException
public static final Cipher getInstance(String transformation,
String provider)
throws NoSuchAlgorithmException,
NoSuchProviderException,
NoSuchPaddingException
public static final Cipher getInstance(String transformation,
Provider provider)
throws NoSuchAlgorithmException,
NoSuchPaddingException

You indicated that you used only one parameter (like the first one
above), but that one doesn't throw the NoSuchProvider exception you
say you got. Something's fishy about that- it just doesn't make
sense! Maybe it's expecting you to use the parameters for some
reason. I probably wasn't much help, but good luck figuring it out!

Light travels faster than sound. This is why some people appear
