Find a certificate in the database with the given issuer and serial number.
Syntax
#include <cert.h>
CERTCertificate *CERT_FindCertByIssuerAndSN (
CERTCertDBHandle *handle,
CERTIssuerAndSN *issuerAndSN );
Parameters
handle | in pointer to a CERTCertDBHandle representing the certificate database to look in |
issuerAndSN | in pointer to a CERTIssuerAndSN that must be properly formed to contain the issuer name and the serial number (see [Example]) |
Description
This function creates a certificate key using the issuerAndSN and it then
uses the key to find the matching certificate in the database.
Returns
A pointer to a CERTCertificate representing the certificate in the database that matched the issuer and serial number, or NULL if none was found. The certificate is a shallow copy, use CERT_DestroyCertificate to decrement the reference count on the certificate instance.
Example
CERTIssuerAndSN issuerSN;
issuerSN.derIssuer.data = caName->data;
issuerSN.derIssuer.len = caName->len;
issuerSN.serialNumber.data = authorityKeyID->authCertSerialNumber.data;
issuerSN.serialNumber.len = authorityKeyID->authCertSerialNumber.len;
issuerCert = CERT_FindCertByIssuerAndSN(cert->dbhandle, &issuerSN);
if ( issuerCert == NULL ) {
PORT_SetError (SEC_ERROR_UNKNOWN_ISSUER);
}
