saveContractCertificateChain - Path to keystore

[PySchilling]

Dear Marc,

I come to one place in the code and the intention is not clear to me where to store the keystore after and updateing or installing certificates.

public static boolean saveContractCertificateChain(
		String keyStorePassword, 
		CertificateChainType contractCertChain,
		ECPrivateKey contractCertPrivateKey) {
		
KeyStore keyStore = getKeyStore(GlobalValues.EVCC_KEYSTORE_FILEPATH.toString(), keyStorePassword);

try {
	if (isPrivateKeyValid(contractCertPrivateKey, contractCertChain)) {
		keyStore.setKeyEntry(
				GlobalValues.ALIAS_CONTRACT_CERTIFICATE.toString(), 
				contractCertPrivateKey, 
				keyStorePassword.toCharArray(), 
				getCertificateChain(contractCertChain)); 
				
		// Save the keystore persistently
		try(FileOutputStream fos = new FileOutputStream("evccKeystore.jks")){
			keyStore.store(fos, 
                                  GlobalValues.PASSPHRASE_FOR_CERTIFICATES_AND_KEYS.toString().toCharArray());
		        }

Should the saved keystore be a different one or should update the exitsing one?

// Save the keystore persistently
try(FileOutputStream fos = new FileOutputStream(GlobalValues.EVCC_KEYSTORE_FILEPATH.toString())){
	keyStore.store(fos, 
        GlobalValues.PASSPHRASE_FOR_CERTIFICATES_AND_KEYS.toString().toCharArray());
}

Best regards,
Volker

Hi Volker,
you're right, good point. You should use the value stated in GlobalValues. EVCC_KEYSTORE_FILEPATH. The "evccKeystore.jks" is a hard-coded value that shouldn't be there. I took care of it wit commit ce7c41d.
