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
E_INVALIDARG
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.
