OCSP_CRL_REFERENCE Struct Reference

Represents the CRL References extension for an OCSP response.

It holds one of three possible data items:

A URL where the CRL is available
A CRL number
The time at which the relevant CRL was created.

Because url, number, and time are mutually exclusive they are defined as a union in the this structure. The default criticality for this extension is NON_CRITICAL. An OCSP response can contain only one extension of this structure for each certificate for which status is being requested. This extension can be present only in an EXTENSIONS_OBJ of type OCSP_SINGLE_EXTENSIONS_OBJ. Use the OCSP_CRL_REFERENCE structure with C_AddExtensionValue() and C_GetExtensionValue().

#include <certext.h>

  OCSP_CRLREF_TYPE   type;

  union {
    ITEM             url;
    ITEM             number;
    GENERALIZED_TIME time;
  } info;
} OCSP_CRL_REFERENCE;
