Lists the certificates in a store (see the ListStoreCertificates method).
The 'callback' is called when the 'CertList' event is emited.
The argument 'e' has the following properties:
e.certEncoded (buffer) e.certSubject e.certIssuer e.certSerialNumber e.hasPrivateKey
The CertSubject and CertIssuer parameters contain distinguished names of the certificate owner and issuer respectively. The HasPrivateKey flag shows whether the private key for the certificate is available in the system.
