+/** Wrapper for a PGPPublicKey.

+ * The methods implemented in this class are a thin layer over
+ * UncachedPublicKey. The difference between the two classes is that objects of
+ * this class can only be obtained from a WrappedKeyRing, and that it stores a
+ * back reference to its parent as well. A method which works with
+ * WrappedPublicKey is therefore guaranteed to work on a KeyRing which is
+ * stored in the database.
