X509NameConstraintsExtension Class

The name constraints extension, which MUST be used only in a CA certificate, indicates a name space within which all subject names in subsequent certificates in a certification path MUST be located. Restrictions apply to the subject distinguished name and apply to subject alternative names. Restrictions apply only when the specified name form is present. If no name of the type is in the certificate, the certificate is acceptable. More details about Name constraints extension processing: RFC 5280.

Syntax
public sealed class X509NameConstraintsExtension : X509Extension

The X509NameConstraintsExtension type exposes the following members.

Constructors
  NameDescription
Public methodX509NameConstraintsExtension(AsnEncodedData)
Intitializes a new instance of X509NameConstraintsExtension class from ASN.1-encoded Name Constraints extension value. Name Constraints extension is always marked critical.
Public methodX509NameConstraintsExtension(X509AlternativeNameCollection, X509AlternativeNameCollection)
Intitializes a new instance of X509NameConstraintsExtension class from a collection of explicitly permitted and excluded subtrees. Name Constraints extension is always marked critical.

Properties
  NameDescription
Public propertyCritical
Gets a Boolean value indicating whether the extension is critical.
(Inherited from X509Extension.)
Public propertyExcludedSubtree
Gets a collection of explicitly disallowed names. Any name matching a restriction in this collection is invalid regardless of information appearing in the PermittedSubtree member.
Public propertyOid
Gets or sets the Oid value for an AsnEncodedData object.
(Inherited from AsnEncodedData.)
Public propertyPermittedSubtree
Gets a collection of explicitly allowed names. Any name matching a restriction in this collection is valid only if it is not listed in the ExcludedSubtree collection. member.
Public propertyRawData
Gets or sets the Abstract Syntax Notation One (ASN.1)-encoded data represented in a byte array.
(Inherited from AsnEncodedData.)
