java.lang.Object

org.refcodes.security.alt.chaos.ChaosEncrypter

All Implemented Interfaces:

org.refcodes.mixin.Disposable, org.refcodes.security.Encrypter<byte[],byte[],org.refcodes.security.EncryptionException>

public class ChaosEncrypter
extends Object
implements org.refcodes.security.Encrypter<byte[],byte[],org.refcodes.security.EncryptionException>

Constructor Details

ChaosEncrypter

public ChaosEncrypter(ChaosKey aKey)

Instantiates a new ChaosEncrypter using the given ChaosKey for encrypting.

Parameters:

aKey - The ChaosKey to use for encrypting.

ChaosEncrypter

public ChaosEncrypter(ChaosKey aKey,
 int aChildDepth)

Instantiates a new ChaosEncrypter using the given ChaosKey for encrypting.

Parameters:

aKey - The ChaosKey to use for encrypting.

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

ChaosEncrypter

public ChaosEncrypter(ChaosKey aKey,
 boolean isVerify)

Instantiates a new ChaosEncrypter using the given ChaosKey for encrypting.

Parameters:

aKey - The ChaosKey to use for encrypting.

isVerify - When true then the encryption is verified against an according live decryption to throw an IllegalStateException in case encryption and decryption differ.

ChaosEncrypter

public ChaosEncrypter(ChaosKey aKey,
 int aChildDepth,
 boolean isVerify)

Instantiates a new ChaosEncrypter using the given ChaosKey for encrypting.

Parameters:

aKey - The ChaosKey to use for encrypting.

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

isVerify - When true then the encryption is verified against an according live decryption to throw an IllegalStateException in case encryption and decryption differ.

ChaosEncrypter

protected ChaosEncrypter(ChaosKey aKey,
 int aChildDepth,
 ChaosEncrypter aChildEncrypter,
 boolean isVerify)

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

Parameters:

aKey - The ChaosKey to use for encrypting.

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

aChildEncrypter - The ChaosEncrypter to be used as child encrypter.

isVerify - When true then the encryption is verified against an according live decryption to throw an IllegalStateException in case encryption and decryption differ.

Throws:

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