/**
 * When the server requests a certificate, and if it does not specify which one it wants (e.g. if server has trusted
 * CA's or trusted certificates, it can specify CN of the cerificate when asking for the client certificate), the
 * client can send any certificate from its keystore. I.e. if we have multiple certificates in the keystore, and we
 * want to do a request with a specific one out of all of them, we should provide it when asked. It can be done by
 * using for each request this private key strategy, that would serve the certificate with specified alias from
 * the keystore, when asked.
