DSAKeyPairGenerator

java.security.interfaces.DSAKeyPairGenerator

Class Overview

The interface for key generators that can generate DSA key pairs.

Summary

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

Public Methods

public abstract void initialize (int modlen, boolean genParams, SecureRandom random)

Since: API Level 1

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.

public abstract void initialize (DSAParams params, SecureRandom random)

Since: API Level 1

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.
