All Implemented Interfaces:

public class ChaosEncryptionOutputStream
extends org.refcodes.security.EncryptionOutputStream

A ChaosEncryptionOutputStream wraps an OutputStream and produces output bytes by applying a ChaosEncrypter on each byte to be written before delegating the processed vale to the given OutputStream. The output of the ChaosEncryptionOutputStream can be converted back by the according ChaosDecryptionInputStream. In case salting is enabled, then the ChaosEncryptionOutputStream initially encrypts heading bytes of an OutputStream with a random salt ChaosKey which then is used as initially encrypting the plan data (being reversed using the ChaosDecryptionInputStream with salting enabled).

Constructor Detail

ChaosEncryptionOutputStream

public ChaosEncryptionOutputStream(OutputStream aOutputStream,
                                   ChaosKey aKey)
                            throws IOException

Constructs the ChaosEncryptionOutputStream using the given ChaosKey for encrypting.

Parameters:

aOutputStream - The OutputStream to be wrapped.

aKey - The ChaosKey to use for encrypting.

Throws:

IOException - Signals that an I/O exception has occurred while applying salting.

ChaosEncryptionOutputStream

public ChaosEncryptionOutputStream(OutputStream aOutputStream,
                                   ChaosKey aKey,
                                   boolean isVerify)
                            throws IOException

Constructs the ChaosEncryptionOutputStream using the given ChaosKey for encrypting.

Parameters:

aOutputStream - The OutputStream to be wrapped.

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.

Throws:

IOException - Signals that an I/O exception has occurred while applying salting.
