There is no such thing as "PKCS7Padding". Did you perhaps mean "PKCS5Padding"?

<http://java.sun.com/j2se/1.4.2/docs/guide/security/jce/JCERefGuide.html#AppA>

Also see the PKCS references:

You shouldn't be getting a NoSuchProviderException. You should be getting
a NoSuchPaddingException, since the method you're calling doesn't have a
"provider name" parameter.
