Method Detail

corePad

final byte[] corePad(byte[] input,
                     int inputLen)
              throws javax.crypto.IllegalBlockSizeException

Specified by:

corePad in class Padding

---

coreUnPad

final int coreUnPad(byte[] input,
                    int inputLen)

Specified by:

coreUnPad in class Padding

---

getPadSize

final int getPadSize(int inputLen)

Specified by:

getPadSize in class Padding

---

getInstance

static Padding getInstance(java.lang.String padding,
                           Mode mode)
                    throws javax.crypto.NoSuchPaddingException

Factory method for obtaining different padding type objects. This method accept a padding name and a Mode instance and returns a Padding instance that wraps the given Mode instance. This class is package protected therefore the various padding types can be (and are) hardcoded here.

---

getBlockSize

final int getBlockSize()

This method delegates to the wrapped Mode instance.

---

getOutputSize

final int getOutputSize(int inputLen)

---

getParamSpec

final java.security.spec.AlgorithmParameterSpec getParamSpec()

This method delegates to the wrapped Mode instance.

---

getIV

final byte[] getIV()

This method delegates to the wrapped Mode instance.

---

init

final void init(boolean decrypt,
                java.security.Key key,
                java.security.spec.AlgorithmParameterSpec params,
                java.security.SecureRandom random)
         throws java.security.InvalidKeyException,
                java.security.InvalidAlgorithmParameterException

This method delegates to the wrapped Mode instance.

---

update

final int update(byte[] input,
                 int inputOffset,
                 int inputLen,
                 byte[] output,
                 int outputOffset)
          throws javax.crypto.ShortBufferException

This method delegates to the wrapped Mode instance.

---

doFinal

final int doFinal(byte[] input,
                  int inputOffset,
                  int inputLen,
                  byte[] output,
                  int outputOffset)
           throws javax.crypto.ShortBufferException,
                  javax.crypto.IllegalBlockSizeException,
                  javax.crypto.BadPaddingException
