Modifier and Type	Method	Description
`int`	`getBlockSize()`
`int`	`getIVSize()`
`void`	`init(Cipher.Mode mode, byte[] key, byte[] iv)`	Initialize the cipher for encryption or decryption with the given private key and initialization vector
`void`	`update(byte[] input, int inputOffset, int inputLen)`	Performs in-place encryption or decryption on the given data.

- Method Detail
  - getBlockSize
```
int getBlockSize()
```
    Returns:
    
    the block size for this cipher
  - getIVSize
```
int getIVSize()
```
    Returns:
    
    the size of the initialization vector
  - init
```
void init(Cipher.Mode mode,
          byte[] key,
          byte[] iv)
```
