Interface CipherVersionGenerator<CV extends CipherVersion>

Type Parameters:
CV - The type of the CipherVersion to be generated.
All Superinterfaces:
org.refcodes.generator.Generator<CV>, Iterator<CV>
All Known Subinterfaces:
EncryptionService
All Known Implementing Classes:
AbstractCipherVersionGenerator, AbstractEncryptionService, CipherVersionGeneratorImpl, LoopbackEncryptionService, PublicKeyEncryptionService
public interface CipherVersionGenerator<CV extends CipherVersion> extends org.refcodes.generator.Generator<CV>
Depending on the security demands and performance issues; the Generator generating CipherVersion instances can be replaced with a custom CipherVersionGenerator using its own approach generating ciphers and cipher UIDs (CipherVersion instances).

In case you provide your custom CipherVersionGenerator implementation, make sure the CipherVersion (sub-)type you return fits with the CipherVersion (sub-)type of your custom CipherVersionFactory. A good approach is to make your custom CipherVersionGenerator make use your custom CipherVersionFactory.

See the default implementations CipherVersionGeneratorImpl, the AbstractCipherVersionGenerator and the CipherVersionFactoryImpl.

    • next

      CV next()
      Generator method to be implemented by subclasses. Required to create implementation dependent cipher version objects. Retrieves the next valid cipher which may be used for encrypting data.
      Specified by:
      next in interface org.refcodes.generator.Generator<CV extends CipherVersion>
      Specified by:
      next in interface Iterator<CV extends CipherVersion>
      Returns:
      The next valid CipherVersion for encryption.
