After Security Update: "Default Password p12 Keys" it is not so clear how to provide a p12 certificate password in the cybersource properties file. If I use "keyPassword" property in the properties file, I receive following error in the log:

“com.cybersource.ws.client.ClientException: Signature creation failed”

If to remove "keyPassword" property from the cybersource properties file it is working correctly, but only for a day or two and after that error appeared in the log: java.io.IOException: PKCS12 key store mac invalid - wrong password or corrupted file.
