FriendlyName	Gets or sets the friendly name for the certificate.
HasPrivateKey	Gets a value indicating whether the certificate has a private key.
IsPerUser	Gets whether the certificate is per-user.
IsSecurityDeviceBound	Gets whether the security device is bound.
IsStronglyProtected	Gets a value that indicates whether the private key associated with the certificate is strongly protected.
Issuer	Gets the Common Name (CN) of the certificate issuer.
KeyAlgorithmName	Gets the name of the cryptographic algorithm used to create the key.
