Class KeyGenerator

java.lang.Object

com.beowulfchain.beowulfj.util.KeyGenerator

public class KeyGenerator
extends Object

This class can be used to generate a new public, private and brain key. It is more or less the Java implementation of the original graphene implementation that can be found on GitHub.

Constructor Summary

Constructors

Constructor and Description
KeyGenerator() Like KeyGenerator(String, int) but automatically suggests a new brain key and uses the sequence 0.
KeyGenerator(String brainKey, int sequence) Create a private and a public key based on the given brain key and the given sequence.

Constructor Detail

KeyGenerator

public KeyGenerator()
             throws BeowulfKeyHandlingException

Like KeyGenerator(String, int) but automatically suggests a new brain key and uses the sequence 0.

Throws:

BeowulfKeyHandlingException - If the an algorithm used by the random generator and to generate a private key is not supported on your platform.

KeyGenerator

public KeyGenerator(String brainKey,
                    int sequence)
             throws BeowulfKeyHandlingException

Create a private and a public key based on the given brain key and the given sequence. Notice that this method uses the SecureRandom.getInstanceStrong() method to generate random numbers. The algorithm used by this method can be changed by configuring the securerandom.strongAlgorithms Security property.

Parameters:

brainKey - The brain key used to generate a new key pair.

sequence - The sequence.

Throws:

BeowulfKeyHandlingException - If the an algorithm used by the random generator and to generate a private key is not supported on your platform.

Method Detail

suggestBrainKey

public static String suggestBrainKey()
                              throws BeowulfKeyHandlingException

Generate a new brain key. Notice that this method uses the SecureRandom.getInstanceStrong() method to generate random numbers. The algorithm used by this method can be changed by configuring the securerandom.strongAlgorithms Security property.

Returns:

The generated brain key.

Throws:

BeowulfKeyHandlingException - If the algorithm used by the random generator is not supported on your platform.

getPrivateKey

public eu.bittrade.crypto.core.ECKey getPrivateKey()

Get the generated private key.

Returns:

The generated private key.

getPrivateKeyAsWIF

public String getPrivateKeyAsWIF()

Get the uncompressed private key in a WI-Format.

Returns:

The uncompressed private key in a WI-Format.

getPublicKey

public PublicKey getPublicKey()

Get the generated public key.

Returns:

The generated public key.

getBrainKey

public String getBrainKey()

Get the generated brain key.

Returns:

The generated brain key.
