Description

Currently the KeyVersion does not provide a way to get the key name to do a reverse lookup to get the metadata of the key.

For the JavaKeyStoreProvider and the UserProvider this is not an issue because the key name is encoded in the key version name.

This encoding of the key name in the key version name cannot be expected in all KeyProvider implementations. It is common for key management systems to use UUID to refer to specific key materials (KeyVersions in Hadoop parlance).
