The ImportCertificate method imports a certificate into the CA database.

 HRESULT ImportCertificate(
   [in, string, unique] wchar_t const* pwszAuthority,
   [in, ref] CERTTRANSBLOB* pctbCertificate,
   [in] LONG dwFlags,
   [out] LONG* pdwRequestId
 );

pwszAuthority: See the pwszAuthority definition in section 3.1.4.1.1.

pctbCertificate: A CERTTRANSBLOB that contains an ASN.1 DER–encoded (as specified in [X660] and [X690]) certificate that is inserted into the CA database.

dwFlags: A LONG value that MUST take one of the following values.

Value	Meaning
0	If this value is set, the CA server does not allow certificates that are not issued by it to be imported into its database.
FLAG_ALLOW_IMPORT_FOREIGN 0x00010000	A request to the CA server to allow certificates that are not issued by it to be imported into its database.
ICF_EXISTINGROW 0x00020000	A request to the CA to associate the imported certificates with an existing request row.

Value

Meaning

If this value is set, the CA server does not allow certificates that are not issued by it to be imported into its database.

FLAG_ALLOW_IMPORT_FOREIGN

0x00010000

A request to the CA server to allow certificates that are not issued by it to be imported into its database.

ICF_EXISTINGROW

0x00020000

A request to the CA to associate the imported certificates with an existing request row.

pdwRequestId: Returns the request ID for the imported certificate. This is used to refer to the certificate after it is imported into the database.

ImportCertificate imports a certificate into the CA database Request table.

The CA server MUST apply the following processing rules:

The CA server MUST enforce that the pctbCertificate parameter value represents an ASN.1 DER–encoded certificate (as specified in [X660]). If not, it MUST fail with the error ERROR_INVALID_DATA (0x8007000D).
The CA server MUST validate the signature on the certificate by using the public key that is associated with the CA's signing certificates.
If the ICF_EXISTINGROW flag is not passed as the value of dwFlags, if the signature validation succeeds (at step 2), and if the certificate does not already exist in the Request table (this is checked by searching on the Serial_Number in the certificate in the database), the certificate MUST be added to the Request table as a new row and the CA MUST return the resulting Request_Request_ID to the client. For processing rules for each data element in the Request table, see the ImportCertificate data element in the following table.
If the ICF_EXISTINGROW flag is not passed as the value of dwFlags, if the signature validation succeeds (at step 2), and if the certificate is already present in the Request table, the CA MUST fail with the error ERROR_OBJECT_EXISTS.
If the ICF_EXISTINGROW flag is passed as the value of dwFlags, if the signature validation succeeds (at step 2), and if the certificate does not already exist in the Request table (this is checked by searching on the Serial_Number in the certificate in the database):

The CA MUST locate an entry in the Request table whose Request_Disposition is "request pending" and whose Request_ID has an entry in the Extensions table with a Subject Key Identifier equal to the SubjectKeyIdentifier extension of the certificate that is passed as pctbCertificate.
1. If the entry is found in the Request Table, the CA MUST update the fields from the information in the certificate. For processing rules for each data element in the Request table, see the ImportCertificate processing rules in the following table. The CA MUST return the Request_Request_ID of the updated Request table row as the pdwRequestId parameter.
2. If the entry is not found in the Request table, the CA MUST fail with the error 0x80092009 (CRYPT_E_NO_MATCH).
If the signature validation fails (at step 2) and FLAG_ALLOW_IMPORT_FOREIGN is not passed as a value of dwFlags, the CA MUST fail with the error 0x800b0107, according to the ImportCertificate data element processing rules in the following table.
If the signature validation fails (at step 2) and FLAG_ALLOW_IMPORT_FOREIGN is passed as value of dwFlags and the certificate is already present in the Request table, the CA SHOULD return the resulting Request_Request_ID to the client. For processing rules for each data element in the Request table, see the ImportCertificate processing rules in the following table.<61>
If the signature validation fails (at step 2), if FLAG_ALLOW_IMPORT_FOREIGN is passed as the value of dwFlags, and if the certificate is not already present in the Request table, the certificate SHOULD be added to the Request table as a new row and the CA SHOULD return the resulting Request_Request_ID to the client. For processing rules for each data element in the Request table, see the ImportCertificate data element in the following table.<62>

The certificate fields and extensions SHOULD be processed and stored in individual Request table fields according to the rules in the following table.
