CertCreateCRLContext function (wincrypt.h)
The CertCreateCRLContext function creates a certificate revocation list (CRL) context from an encoded CRL. The created context is not persisted to a certificate store. It makes a copy of the encoded CRL within the created context.
Syntax
PCCRL_CONTEXT CertCreateCRLContext(
[in] DWORD dwCertEncodingType,
[in] const BYTE *pbCrlEncoded,
[in] DWORD cbCrlEncoded
);
Parameters
[in] dwCertEncodingType
Specifies the type of encoding used. It is always acceptable to specify both the certificate and message encoding types by combining them with a bitwise-OR operation as shown in the following example:
X509_ASN_ENCODING | PKCS_7_ASN_ENCODING Currently defined encoding types are:
- X509_ASN_ENCODING
- PKCS_7_ASN_ENCODING
[in] pbCrlEncoded
A pointer to a buffer containing the encoded CRL from which the context is to be created.
[in] cbCrlEncoded
The size, in bytes, of the pbCrlEncoded buffer.
Return value
If the function succeeds, the return value is a pointer to a read-only CRL_CONTEXT.
If the function fails and is unable to decode and create the CRL_CONTEXT, the return value is NULL. For extended error information, call GetLastError. The following table shows a possible error code.
Return code | Description |
---|---|
|
Invalid certificate encoding type. Currently, only the encoding type X509_ASN_ENCODING is supported. |
If the function fails, GetLastError may return an Abstract Syntax Notation One (ASN.1) encoding/decoding error. For information about these errors, see ASN.1 Encoding/Decoding Return Values.
Remarks
The CRL_CONTEXT must be freed by calling CertFreeCRLContext. CertDuplicateCRLContext can be called to make a duplicate. CertSetCRLContextProperty and CertGetCRLContextProperty can be called to store and read properties for the CRL.
