Class KeyStoreHelper

java.lang.Object

org.drools.core.util.KeyStoreHelper

public class KeyStoreHelper
extends Object

A helper class to deal with the key store and signing process during Serialisation

This class will read and use the following system properties:

drools.serialization.sign = drools.serialization.private.keyStoreURL = drools.serialization.private.keyStorePwd = drools.serialization.private.keyAlias = drools.serialization.private.keyPwd = drools.serialization.public.keyStoreURL = drools.serialization.public.keyStorePwd =

KeyStore	getPvtKeyStore()
char[]	getPvtKeyStorePwd()
URL	getPvtKeyStoreURL()
boolean	isSigned()
static void	reInit()
byte[]	signDataWithPrivateKey(byte[] data)	Generates the signature for the given byte[] using MD5 with RSA algorithm and the private key with which this helper was initialised.

                                     SignatureException

Generates the signature for the given byte[] using MD5 with RSA algorithm and the private key with which this helper was initialised.

Parameters:

data - the byte[] of data to be signed

Returns:

the signature, encrypted with the private key

Throws:

UnrecoverableKeyException

KeyStoreException

NoSuchAlgorithmException

InvalidKeyException

SignatureException

checkDataWithPublicKey

public boolean checkDataWithPublicKey(String publicKeyAlias,
                                      byte[] data,
                                      byte[] signature)

                                      SignatureException

Checks the given byte[] data against the signature, using the public key with which this helper was initialised and the algorithm MD5 with RSA.

Parameters:

data - the original data that was signed

signature - the provided signature

Returns:

true in case the signature matches, false otherwise.

Throws:

KeyStoreException
