Create .p7s Compliant with ICP-Brazil Digital Signature Standard

See more CAdES Examples

Demonstrates how to create a .p7s signature that contains a data file, which in this case is a PDF. The .p7s will be compliant with the ICP-Brazil Digital Signature Standard.

Important: This example requires Chilkat v9.5.0.92 or later.

    // This example requires the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    CkCrypt2 crypt;

    // Any type of file can be signed.  It doesn't have to be a PDF.
    const char *inFile = "qa_data/pdf/helloWorld.pdf";

    CkBinData bd;
    success = bd.LoadFile(inFile);
    if (success == false) {
        std::cout << "Failed to load " << inFile << "\r\n";
        return;
    }

    // Get the certificate we'll be using to sign.
    CkCert cert;

    success = cert.LoadPfxFile("qa_data/pfx/cert_test123.pfx","test123");
    if (success == false) {
        std::cout << cert.lastErrorText() << "\r\n";
        return;
    }

    success = crypt.SetSigningCert(cert);
    if (success == false) {
        std::cout << crypt.lastErrorText() << "\r\n";
        return;
