Cryptographic object identifiers consist of a value/name pair. If one property in a pair is set to a known value, the other property is updated automatically to a corresponding value. For example, if the Value property is set to "1.3.6.1.5.5.7.3.4", the FriendlyName property, which is localized, is set automatically to "Secure Email".
