X509ApplicationPolicyConstraintsExtension Class

Represents the X.509 Application Policy Constraints certificate extension. The policy constraints extension can be used in certificates issued to CAs.The policy constraints extension constrains path validation in two ways. It can be used to prohibit policy mapping or require that each certificate in a path contain an acceptable policy identifier.

Constructors

X509ApplicationPolicyConstraintsExtension(AsnEncodedData) Initializes a new instance of the X509ApplicationPolicyConstraintsExtension class from an AsnEncodedData object.
X509ApplicationPolicyConstraintsExtension(NullableInt32, NullableInt32) Initializes a new instance of the X509ApplicationPolicyConstraintsExtension class from a minimum and maximum number of certificates with required application policy.

Properties

InhibitPolicyMapping Gets the number of additional certificates that may appear in the path before policy mapping is no longer permitted. For example, a value of one indicates that policy mapping may be processed in certificates issued by the subject of this certificate, but not in additional certificates in the path.
RequireExplicitPolicy Gets the number of additional certificates that may appear in the path before an explicit policy is required for the entire path. When an explicit policy is required, it is necessary for all certificates in the path to contain an acceptable policy identifier in the certificate policies extension. An acceptable policy identifier is the identifier of a policy required by the user of the certification path or the identifier of a policy that has been declared equivalent through policy mapping.
