setKey
protected void setKey(java.security.Key inKey)
throws java.security.InvalidKeyException
- Re-key the cipher. If the provided Key is not compatible
with this cipher the exception should throw an InvalidKeyException.
- Parameters:
inKey
- the key to be used.- Throws:
- java.security.InvalidKeyException - if the key is of the wrong type.
- Overrides:
- setKey in class BlockCipher
engineSetPadding
protected void engineSetPadding(java.lang.String padding)
throws NoSuchPaddingException
- Sets the padding mechanism of this cipher.
- Parameters:
padding
- the name of the type of padding to be applied,
currently "PKCS7Padding", and "NoPadding" will
be accepted.- Throws:
- NoSuchPaddingException - if the padding type is unknown.
- Overrides:
- engineSetPadding in class BlockCipher
engineGetBlockSize
protected int engineGetBlockSize()
- Returns the block size (in bytes).
- Returns:
- the block size (in bytes) of the cipher.
- Overrides:
- engineGetBlockSize in class BlockCipher
encryptBlock
protected int encryptBlock(byte[] src,
int srcIndex,
int len,
byte[] dst,
int dstIndex)
throws IllegalBlockSizeException
- Encrypt the given input starting at the given offset and place
the result in the provided buffer starting at the given offset.
The input will be an exact multiple of our blocksize.
- Overrides:
- encryptBlock in class BlockCipher
decryptBlock
protected int decryptBlock(byte[] src,
int srcIndex,
int len,
byte[] dst,
int dstIndex)
throws BadPaddingException
- Decrypt the given input starting at the given offset and place
the result in the provided buffer starting at the given offset.
The input will be an exact multiple of our blocksize.
- Overrides:
- decryptBlock in class BlockCipher
