Method Detail RC4 public void RC4()(Code) Constructor for algorithm 3 (ALG_ARCFOUR) doFinal public int doFinal(byte[] inBuf, int inOff, int inLen, byte[] outBuf, int outOff) throws CryptoException(Code) Process the final data record. Parameters:   inBuf - input buffer of data Parameters:   inOff - offset in the provided input buffer Parameters:   inLen - length of data to be processed Parameters:   outBuf - output buffer of data Parameters:   outOff - offset in the provided output buffer number of bytes copied to output buffer exception:   CryptoException - is thrown, if there are errors in the arguments getAlgorithm public byte getAlgorithm()(Code) Get the alorithm (ALG_ARCFOUR). algorithm 3 code init public void init(Key theKey, byte theMode, byte[] b, int off, int len) throws CryptoException(Code) Initialize the alorithm with initial data. (Not supported) Parameters:   theKey - public key Parameters:   theMode - mode of operation Parameters:   b - buffer of data Parameters:   off - offset in the provided buffer Parameters:   len - length of data to be processed exception:   CryptoException - is thrown, because the method is not supported. init public void init(Key theKey, byte theMode) throws CryptoException(Code) Initializes the cipher's S-boxes based on the key. This code is based on the cipher's description in Bruce Schenier's "Applied Cryptography", Second Edition, pp 397-398, ISBN 0-471-11709-9 Parameters:   theKey - public key Parameters:   theMode - mode of operation exception:   CryptoException - is thrown, if there is an error in the arguments. transform public int transform(byte[] inBuf, int inOff, int inLen, byte[] outBuf, int outOff)(Code) Transform a buffer of data, Parameters:   inBuf - input buffer of data Parameters:   inOff - offset in the provided input buffer Parameters:   inLen - length of data to be processed Parameters:   outBuf - output buffer of data Parameters:   outOff - offset in the provided output buffer number of bytes copied to output buffer update public int update(byte[] inBuf, int inOff, int inLen, byte[] outBuf, int outOff) throws CryptoException(Code) Update the current data record. Parameters:   inBuf - input buffer of data Parameters:   inOff - offset in the provided input buffer Parameters:   inLen - length of data to be processed Parameters:   outBuf - output buffer of data Parameters:   outOff - offset in the provided output buffer number of bytes copied to output buffer exception:   CryptoException - is thrown, if there are errors in the arguments Fields inherited from com.sun.portal.kssl.Cipher final public static byte ALG_ARCFOUR(Code)(Java Doc) final public static byte ALG_DES(Code)(Java Doc) final public static byte ALG_RSA_PKCS1(Code)(Java Doc) final public static byte ALG_TRIPLEDES(Code)(Java Doc) final public static byte ALG_UNKNOWN(Code)(Java Doc) final public static byte MODE_DECRYPT(Code)(Java Doc) final public static byte MODE_ENCRYPT(Code)(Java Doc) final protected static byte MODE_UNKNOWN(Code)(Java Doc) Methods inherited from com.sun.portal.kssl.Cipher abstract public int doFinal(byte[] inBuf, int inOff, int inLen, byte[] outBuf, int outOff) throws CryptoException(Code)(Java Doc) abstract public byte getAlgorithm()(Code)(Java Doc) public static Cipher getInstance(byte alg, boolean ext) throws CryptoException(Code)(Java Doc) abstract public void init(Key theKey, byte theMode) throws CryptoException(Code)(Java Doc) abstract public void init(Key theKey, byte theMode, byte[] b, int off, int len) throws CryptoException(Code)(Java Doc) abstract public int update(byte[] inBuf, int inOff, int inLen, byte[] outBuf, int outOff) throws CryptoException(Code)(Java Doc) Methods inherited from java.lang.Object native protected Object clone() throws CloneNotSupportedException(Code)(Java Doc) public boolean equals(Object obj)(Code)(Java Doc) protected void finalize() throws Throwable(Code)(Java Doc) final native public Class getClass()(Code)(Java Doc) native public int hashCode()(Code)(Java Doc) final native public void notify()(Code)(Java Doc) final native public void notifyAll()(Code)(Java Doc) public String toString()(Code)(Java Doc) final native public void wait(long timeout) throws InterruptedException(Code)(Java Doc) final public void wait(long timeout, int nanos) throws InterruptedException(Code)(Java Doc) final public void wait() throws InterruptedException(Code)(Java Doc)
