public interface EncryptionProvider extends org.refcodes.security.Encrypter<String,String,org.refcodes.security.EncryptionException>
EncryptionProvider
is bound to a namespace and is being used by
the business logic to encrypt data.
It is merely responsible for retrieving a currently valid cipher for
encrypting data. The EncryptionProvider
does not expose the cipher
though it might store it in clear text in-memory only (advanced
implementations might encrypt the in-memory cipher). The (internally)
retrieved cipher is requested from and provided by an
EncryptionService
(on the same machine) which takes care of providing
(and creating) a cipher with a cipher UID as well as publishing the according
CipherVersion
(via the EncryptionServer
to the
DecryptionServer
). As the EncryptionProvider
does not persist
any data, an in-memory CipherVersion
will only be used as long as the
EncryptionProvider
is up-and-running. In case of a restart, a new
cipher for encryption is requested from the EncryptionService
. Also
the encryption provider can be forced to (create and to) use a next valid
cipher on demand.
