Modifier and Type	Method	Description
`void`	`initialize(int modlen, boolean genParams, SecureRandom random)`	Initializes this generator for the specified modulus length.
`void`	`initialize(DSAParams params, SecureRandom random)`	Initializes this generator with the prime (`p`), subprime (`q`), and base (`g`) values from the specified parameters.

- Method Detail
  - initialize
```
void initialize(DSAParams params,
                SecureRandom random)
         throws InvalidParameterException
```
    Initializes this generator with the prime (p), subprime (q), and base (g) values from the specified parameters.
    
    Parameters:
    
    params - the parameter values.
    
    random - the source of randomness.
    
    Throws:
    
    InvalidParameterException - if the specified parameter values are null or invalid.
  - initialize
```
void initialize(int modlen,
                boolean genParams,
                SecureRandom random)
         throws InvalidParameterException
```
    Initializes this generator for the specified modulus length. Valid values for the modulus length are the multiples of 8 between 512 and 1024.
    The parameter genParams specifies whether this method should generate new prime (p), subprime (q), and base (g) values or whether it will use the pre-calculated values for the specified modulus length. Default parameters are available for modulus lengths of 512 and 1024 bits.
    
    Parameters:
    
    modlen - the length of the modulus in bits.
    
    genParams - whether new values should be generated.
    
    random - the source of randomness.
    
    Throws:
    
    InvalidParameterException - if the specified modulus length is not valid, or if there are no pre-calculated values and genParams is false.
