```
public String getAlgorithm()
```

public int getKeyBitLength()
```
    The length of the derived key in bits.
    
    Returns:
  - getKeyLength
```
public int getKeyLength()
```
    The length of the derived key in bytes needed to store the key in bitSize. For example: if the key is 9 bits long, the length of the key in bytes is 2, but the key is stored in 8 bits the length in bytes is 1.
    
    Returns:
    
    the length of the derived key in bytes
