Class ChaosDecrypter

java.lang.Object

org.refcodes.security.alt.chaos.ChaosDecrypter

All Implemented Interfaces:

org.refcodes.mixin.Disposable, org.refcodes.security.Decrypter<byte[],byte[],org.refcodes.security.DecryptionException>

public class ChaosDecrypter
extends Object
implements org.refcodes.security.Decrypter<byte[],byte[],org.refcodes.security.DecryptionException>

The ChaosDecrypter will use byte arrays as input and output types.

Constructor Details

ChaosDecrypter

public ChaosDecrypter(ChaosKey aKey)

Instantiates a new ChaosDecrypter using the given ChaosKey for decrypting.

Parameters:

aKey - The ChaosKey to use for decrypting.

ChaosDecrypter

public ChaosDecrypter(ChaosKey aKey,
 int aChildDepth)

Instantiates a new ChaosDecrypter using the given ChaosKey for decrypting.

Parameters:

aKey - The ChaosKey to use for decrypting.

aChildDepth - The number of children to consider when creating the ChaosDecrypter.

ChaosDecrypter

protected ChaosDecrypter(ChaosKey aKey,
 int aChildDepth,
 ChaosDecrypter aChildDecrypter)
                  throws IllegalArgumentException

Instantiates a new ChaosDecrypter using the given ChaosKey for encrypting and the given ChaosDecrypter as _child encrypter: TThe ChaosKey must therefore have no child ChaosKey as the child ChaosDecrypter then cannot unambiguously be determined! Attention: This constructor usually only is used by libraries which retrieve the various keys in different processing steps (see ChaosDecryptionInputStream).

Parameters:

aKey - The ChaosKey to use for decrypting.

aChildDepth - The number of children to consider when creating the ChaosDecrypter.

aChildDecrypter - The child ChaosDecrypter to be used as child decrypter.

Throws:

IllegalArgumentException - thrown in case the chaos key has a child key and a child decrypter is provided as well (either the one or the other only is allowed).
