Find a PFX Certificate by localKeyId

See more PFX/P12 Examples

Demonstrates Pfx.CertByLocalKeyId, which searches for a certificate whose certificate-bag localKeyId attribute matches a given value and copies it into a Cert object.

The file path is relative to the application's current working directory. An absolute path may also be used. Supply the path appropriate to your own environment.

#include <CkPfxW.h>
#include <CkCertW.h>

void ChilkatSample(void)
    {
    bool success = false;

    CkPfxW pfx;

    //  The file path is relative to the application's current working directory.  An absolute path
    //  may also be used.  Supply the path appropriate to your own environment.
    //  The PFX password should come from a secure source rather than being hard-coded.
    const wchar_t *password = L"myPfxPassword";
    success = pfx.LoadPfxFile(L"qa_data/identity.pfx",password);
    if (success == false) {
        wprintf(L"%s\n",pfx.lastErrorText());
        return;
    }

    //  Find a certificate whose certificate-bag localKeyId attribute matches the given value.  The 2nd
    //  argument names the binary representation of the id, such as decimal, base64, or hex.
    CkCertW cert;
    success = pfx.CertByLocalKeyId(L"01",L"hex",cert);
    if (success == false) {
        wprintf(L"%s\n",pfx.lastErrorText());
        return;
    }

    wprintf(L"Found certificate: %s\n",cert.subjectCN());
    }
