SyntaxThe X509ArchiveCutoffExtension type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | X509ArchiveCutoffExtension |
Initializes a new instance of the X509ArchiveCutoffExtension class.
|
| X509ArchiveCutoffExtension(DateTime) |
Initializes a new instance of the X509ArchiveCutoffExtension class using a cutoff date.
|
| X509ArchiveCutoffExtension(AsnEncodedData, Boolean) |
Initializes a new instance of the X509ArchiveCutoffExtension class using an
AsnEncodedData object and a value that identifies whether the extension is critical.
|
Properties| Name | Description | |
|---|---|---|
 | Critical | Gets a Boolean value indicating whether the extension is critical. (Inherited from X509Extension.) |
| CutoffDate |
Gets a cutoff date and time.
|
| Oid | Gets or sets the Oid value for an AsnEncodedData object. (Inherited from AsnEncodedData.) |
| RawData | Gets or sets the Abstract Syntax Notation One (ASN.1)-encoded data represented in a byte array. (Inherited from AsnEncodedData.) |
Methods| Name | Description | |
|---|---|---|
| CopyFrom | Copies the extension properties of the specified AsnEncodedData object. (Inherited from X509Extension.) |
| Equals | Determines whether the specified object is equal to the current object. (Inherited from Object.) |
 | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
| Format |
Returns a formatted version of the Abstract Syntax Notation One (ASN.1)-encoded data as a string.
(Overrides AsnEncodedDataFormat(Boolean).) |
| GetHashCode | Serves as the default hash function. (Inherited from Object.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
Extension Methods| Name | Description | |
|---|---|---|
 | Encode |
Encodes current extension to ASN.1-encoded byte array.
(Defined by X509ExtensionExtensions.) |
Remarks
An OCSP responder MAY choose to retain revocation information beyond a certificate's expiration.
The date obtained by subtracting this retention interval value from the producedAt time in a response is
defined as the certificate's "archive cutoff" date. OCSP-enabled applications would use an OCSP
archive cutoff date to contribute to a proof that a digital signature was (or was not) reliable on
the date it was produced even if the certificate needed to validate the signature has long since expired.
To illustrate, if a server is operated with a 7-year retention interval policy and status was produced at time t1 then the value for ArchiveCutoff in the response would be (t1 - 7 years).
