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.

DSACertificateExtensions

Provides extension methods for retrieving DSA implementations for the public and private keys of an X509Certificate2.

ECDsaCertificateExtensions

Provides extension methods for retrieving ECDsa implementations for the public and private keys of a X509Certificate2 certificate.

Pkcs12LoaderLimits

Represents a set of constraints to apply when loading PKCS#12/PFX contents.
