Encryption

1. As in the last classtask, run the following.

   http://localhost:8080/social/initial?parameter1=dog&parameter2=cat
   However, modify the initial action to also have it return the encrypted value of dog,cat, e.g. dog cat UJEysczgbMpxUq2dUY3J8A==

2. Update your application with a new action so that a request like
   http://localhost:8080/social/initial3?parameter1=UJEysczgbMpxUq2dUY3J8A== returns the decrypted value, e.g. dog,cat.
