Decrypt2

See more MIME Examples

Demonstrates how to decrypt MIME using a certificate and private key where the certificate and its corresponding private key are stored in separate files -- a .cer for the certificate, and a .pem for the private key. C++

#include <CkMime.h>
#include <CkCert.h>
#include <CkPrivateKey.h>

void ChilkatSample(void)
    {
    bool success = false;

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

    CkMime mime;

    // Load the certificate from a .cer file.
    CkCert cert;
    success = cert.LoadFromFile("aaworkarea/myCert.cer");
    if (success == false) {
        std::cout << cert.lastErrorText() << "\r\n";
        return;
    }

    // Load the private key from an encrypted PEM file.
    // (A private key can be loaded from other file formats also..)
    CkPrivateKey privKey;
    success = privKey.LoadEncryptedPemFile("aaworkarea/myPrivateKey.pem","myPassword");
    if (success == false) {
        std::cout << privKey.lastErrorText() << "\r\n";
        return;
    }

    success = mime.LoadMimeFile("aaworkarea/encryptedMime.txt");
    if (success == false) {
        std::cout << mime.lastErrorText() << "\r\n";
        return;
    }

    // Decrypt using the cert and associated private key
    success = mime.Decrypt2(cert,privKey);
    if (success == false) {
        std::cout << mime.lastErrorText() << "\r\n";
        return;
    }

    // Save the S/MIME to a file.
    success = mime.SaveMime("aaworkarea/decryptedMime.txt");
    if (success == false) {
        std::cout << mime.lastErrorText() << "\r\n";
        return;
    }

    std::cout << "success!" << "\r\n";
