Method Summary

All Methods Instance Methods Concrete Methods
Modifier and Type	Method and Description
`java.security.KeyPair`	`generateKeyPair()`
`void`	`initialize(java.security.spec.AlgorithmParameterSpec paramSpec, java.security.SecureRandom secureRandom)` Setting custom AlgorithmParameterSpec is not supported since the composite signature algorithm definition allow only for one specific parameter spec which is initialized by the initializeParameters method.
`void`	`initialize(int keySize, java.security.SecureRandom random)` Native public method.

  - initialize
```
public void initialize(int keySize,
                       java.security.SecureRandom random)
```
    Native public method. There is no notion of a keysize for composite signatures. Therefore, this method is unsupported. For setting a custom SecureRandom the other initialize method must be used.
    
    Specified by:
    
    initialize in class java.security.KeyPairGeneratorSpi
    
    Parameters:
    
    keySize -
    
    random -
  - initialize
```
public void initialize(java.security.spec.AlgorithmParameterSpec paramSpec,
                       java.security.SecureRandom secureRandom)
                throws java.security.InvalidAlgorithmParameterException
```
    Setting custom AlgorithmParameterSpec is not supported since the composite signature algorithm definition allow only for one specific parameter spec which is initialized by the initializeParameters method. This method only serves to set a custom SecureRandom.
    
    Overrides:
    
    initialize in class java.security.KeyPairGeneratorSpi
    
    Parameters:
    
    paramSpec - Unsupported, needs to be null.
    
    secureRandom - A SecureRandom used by component key generators.
    
    Throws:
    
    java.security.InvalidAlgorithmParameterException
  - generateKeyPair
