public ECNewPublicKeyTransform()
```
- Method Detail
  - init
```
public void init(CipherParameters param)
```
    initialise the EC Elgamal engine.
    
    Specified by:
    
    init in interface ECPairTransform
    
    Parameters:
    
    param - the necessary EC key parameters.
  - transform
```
public ECPair transform(ECPair cipherText)
```
    Transform an existing cipher text pair using the ElGamal algorithm. Note: the input cipherText will need to be preserved in order to complete the transformation to the new public key.
    
    Specified by:
    
    transform in interface ECPairTransform
    
    Parameters:
    
    cipherText - the EC point to process.
    
    Returns:
    
    returns a new ECPair representing the result of the process.
  - createBasePointMultiplier
```
protected ECMultiplier createBasePointMultiplier()
