This function creates a certificate context from an encoded certificate. The created context is not persisted to a certificate store. The function makes a copy of the encoded certificate within the created context.
PCCERT_CONTEXT WINAPI CertCreateCertificateContext( DWORD dwCertEncodingType, const BYTE *pbCertEncoded, DWORD cbCertEncoded );
- [in] Specifies the type of encoding used. Currently, only X509_ASN_ENCODING is used; however, additional encoding types may be added in the future.
- [in] Pointer to a buffer containing the encoded certificate from which the context is to be created.
- [in] Size, in bytes, of the pbCertEncoded buffer.
If the function succeeds, the return value is a pointer to a read-only CERT_CONTEXT structure.
If the function is unable to decode and create the certificate context, the return value is NULL.
For extended error information, call the GetLastError function. The following table lists a possible error code.
|E_INVALIDARG||An invalid certificate encoding type was specified. Currently, only the X509_ASN_ENCODING type is supported.|
The CERT_CONTEXT structure must be freed by calling the CertFreeCertificateContext function. The CertDuplicateCertificateContext function can be called to make a duplicate. The CertSetCertificateContextProperty and CertGetCertificateContextProperty functions can be called to store and read properties for the certificate.
The desktop platform supports the PKCS_7_ASN_ENCODING flag, but Windows CE does not. Windows CE ignores the flag when it is specified.
