org.refcodes.forwardsecrecy.AbstractDecryptionService

org.refcodes.forwardsecrecy.LoopbackDecryptionServiceImpl

All Implemented Interfaces:

DecryptionService

Deprecated.

To prevent accidental use in productive environment this insecure implementation of the DecryptionService has been marked as being deprecated; please use only for testing purposes.

@Deprecated
public class LoopbackDecryptionServiceImpl
extends AbstractDecryptionService

The LoopbackDecryptionServiceImpl is an UNSECURE implementation of the DecryptionService managing the ciphers in the CipherVersion in plan text. This implementation's mere purpose is to provide means to easily set up a quick and dirty test setup. The LoopbackDecryptionServiceImpl is the counterpart of the LoopbackEncryptionServiceImpl which both work (insecurely) hand in hand.

The LoopbackDecryptionServiceImpl must not be used in production environments!

Method Detail

toSignature

protected String toSignature(String aMessage)

Deprecated.

Creates a signature for the given message.

Specified by:

toSignature in class AbstractDecryptionService

Parameters:

aMessage - The message for which a signature is to be generated

Returns:

The signature for the message

createMessage

protected String createMessage()

Deprecated.

Creates a message for which a signature is to be created in order to authenticate for the retrieval of the cipher versions. A decryption server should deny any requests to get cipher versions in case the same message is used twice.

Specified by:

createMessage in class AbstractDecryptionService

Returns:

The message

toDecryptedCipherVersion

@Deprecated
protected <CV extends CipherVersion> CV toDecryptedCipherVersion(CV aEncryptedCipherVersion)

Deprecated. To prevent accidental use in productive environment this insecure implementation of the DecryptionService has been marked as being deprecated; please use only for testing purposes.

Hook factory method to be implemented by subclasses. The provided cipher is to be decrypted (e.g. with the private key of an asymmetric encryption approach) so that an decryption server only receives encrypted data. CAUTION: The encrypted CipherVersion argument is returned unmodified (not decrypted!). Please overwrite this method with a decrypting one!

Specified by:

toDecryptedCipherVersion in class AbstractDecryptionService

Type Parameters:

CV - The type of the CipherVersion to be used.

Parameters:

aEncryptedCipherVersion - The CipherVersion to be decrypted.

Returns:

The decrypted CipherVersion.
