In the previous blog post we described how the client certificates are installed in the Microsoft Windows certificate store.
If you use certificates with Java the certificate and private key will be fetched from the Java keystore. The keystore is a database for storing certificates and password protected private keys. Thus the keystore is protected by a password itself. The utility keytool can be used to create and manage such a keystore database. Also it is possible to use more than one keystore database so you could create an keystore exclusively for use with the BioID Web Service.
