Enumerate Private Keys in a PFX

See more PFX/P12 Examples

Demonstrates Pfx.PrivateKeyAt, which copies the private key at a zero-based index into a PrivateKey object. The example enumerates all private keys in the 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.

#include <CkPfxW.h>
#include <CkPrivateKeyW.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;
    }

    //  Enumerate the private keys in the PFX by zero-based index.  Valid indexes are less than
    //  NumPrivateKeys.
    int numKeys = pfx.get_NumPrivateKeys();
    CkPrivateKeyW privKey;
    int i;
    for (i = 0; i <= numKeys - 1; i++) {
        success = pfx.PrivateKeyAt(i,privKey);
        if (success == false) {
            wprintf(L"%s\n",pfx.lastErrorText());
            return;
        }

        wprintf(L"Private key %d: %s (%d bits)\n",i,privKey.keyType(),privKey.get_BitLength());
    }
