<para>X509 extensions are dynamic, extended properties that can be added to an X509 certificate and changed. The <see cref="T:System.Security.Cryptography.X509Certificates.X509Extension" /> class can be used to create extensions that are associated with a certificate but are not part of a certificate as issued by a certification authority (CA).</para>
|
||
|
|
<para>In its most basic form, an X509 extension has an object identifier (OID), a Boolean value describing whether the extension is considered critical or not, and ASN-encoded data. Custom extensions can be registered in a <see cref="T:System.Security.Cryptography.CryptoConfig" /> file.</para>
