System.Security.Cryptography.X509Certificates Namespace
Visual Studio 2008
The System.Security.Cryptography.X509Certificates namespace contains the common language runtime implementation of the Authenticode X.509 v.3 certificate. This certificate is signed with a private key that uniquely and positively identifies the holder of the certificate.

|---|---|---|
 | AuthenticodeSignatureInformation | Provides information about an Authenticode signature for a manifest. |
| PublicKey | Represents a certificate's public key information. This class cannot be inherited. |
| TimestampInformation | Provides details about the time stamp that was applied to an Authenticode signature for a manifest. |
| X500DistinguishedName | Represents the distinguished name of an X509 certificate. This class cannot be inherited. |
| X509BasicConstraintsExtension | Defines the constraints set on a certificate. This class cannot be inherited. |
| X509Certificate | Provides methods that help you use X.509 v.3 certificates. |
| X509Certificate2 | Represents an X.509 certificate. This class can be inherited. |
| X509Certificate2Collection | Represents a collection of X509Certificate2 objects. This class cannot be inherited. |
| X509Certificate2Enumerator | Supports a simple iteration over a X509Certificate2Collection object. This class cannot be inherited. |

| X509CertificateCollection | Defines a collection that stores X509Certificate objects. |
| X509CertificateCollection::X509CertificateEnumerator | Enumerates the X509Certificate objects in an X509CertificateCollection. |
| X509Chain | Represents a chain-building engine for X509Certificate2 certificates. |
| X509ChainElement | Represents an element of an X.509 chain. |
| X509ChainElementCollection | Represents a collection of X509ChainElement objects. This class cannot be inherited. |
| X509ChainElementEnumerator | Supports a simple iteration over an X509ChainElementCollection. This class cannot be inherited. |
| X509ChainPolicy | Represents the chain policy to be applied when building an X509 certificate chain. This class cannot be inherited. |
| X509EnhancedKeyUsageExtension | Defines the collection of object identifiers (OIDs) that indicates the applications that use the key. This class cannot be inherited. |
| X509Extension | Represents an X509 extension. |
| X509ExtensionCollection | Represents a collection of X509Extension objects. This class cannot be inherited. |

| X509KeyUsageExtension | Defines the usage of a key contained within an X.509 certificate. This class cannot be inherited. |
| X509Store | Represents an X.509 store, which is a physical store where certificates are persisted and managed. This class cannot be inherited. |
| X509SubjectKeyIdentifierExtension | Defines a string that identifies a certificate's subject key identifier (SKI). This class cannot be inherited. |
