    Description copied from interface: AsymmetricCipherKeyPairGenerator
    
    intialise the key pair generator.
    
    Specified by:
    
    init in interface AsymmetricCipherKeyPairGenerator
    
    Parameters:
    
    param - the parameters the key pair is to be initialised with.
  - generateKeyPair
```
public AsymmetricCipherKeyPair generateKeyPair()
```
    Generates a new signature key pair. Starts B+1 threads.
    
    Specified by:
    
    generateKeyPair in interface AsymmetricCipherKeyPairGenerator
    
    Returns:
    
    a key pair
  - generateKeyPairSingleThread
```
public AsymmetricCipherKeyPair generateKeyPairSingleThread()
```
    Generates a new signature key pair. Runs in a single thread.
    
    Returns:
    
    a key pair
  - generateBoundedBasis
```
public NTRUSigningPrivateKeyParameters.Basis generateBoundedBasis()
```
    Creates a basis such that |F| < keyNormBound and |G| < keyNormBound
    
    Returns:
    
    a NTRUSigner basis
