CRL_INFO structure (wincrypt.h)
The CRL_INFO structure contains the information of a certificate revocation list (CRL).
Syntax
typedef struct _CRL_INFO {
DWORD dwVersion;
CRYPT_ALGORITHM_IDENTIFIER SignatureAlgorithm;
CERT_NAME_BLOB Issuer;
FILETIME ThisUpdate;
FILETIME NextUpdate;
DWORD cCRLEntry;
PCRL_ENTRY rgCRLEntry;
DWORD cExtension;
PCERT_EXTENSION rgExtension;
} CRL_INFO, *PCRL_INFO;
Members
dwVersion
Version number of the CRL. Currently defined version numbers are shown in the following table.
| Value | Meaning |
|---|---|
|
version 1 |
|
version 2 |
SignatureAlgorithm
CRYPT_ALGORITHM_IDENTIFIER structure that contains the object identifier (OID) of a signature algorithm and any associated additional parameters.
Issuer
A BLOB structure that contains an encoded certificate issuer's name.
ThisUpdate
Indication of the date and time of the CRL's published. If the time is after 1950 and before 2050, it is UTC-time encoded as an 8-byte date/time precise to seconds with a 2-digit year (that is, YYMMDDHHMMSS plus 2 bytes). Otherwise, it is generalized-time encoded as an 8-byte year precise to milliseconds with a 4-byte year.
NextUpdate
Indication of the date and time for the CRL's next available scheduled update. If the time is after 1950 and before 2050, it is UTC-time encoded as an 8-byte date/time precise to seconds with a 2-digit year (that is, YYMMDDHHMMSS plus 2 bytes). Otherwise, it is generalized-time encoded as an 8-byte date time precise to milliseconds with a 4-byte year.
cCRLEntry
Number of elements in the rgCRLEntry array.
rgCRLEntry
Array of pointers to CRL_ENTRY structures. Each of these structures represents a revoked certificate.
cExtension
Number of elements in the rgExtension array.
rgExtension
Array of pointers to CERT_EXTENSION structures, each holding information about the CRL.
