PKCS7 Decrypt MIME

See more MIME Examples

Loads a PKCS7 encrypted MIME file and decrypts. The cert and private key used for decryption is loaded from a PFX file. C++

#include <CkMime.h>

    bool success = false;

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

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

    //  The AddPfxSourceFile and/or AddPfxSourceData
    //  methods may be called one or more times (one per PFX)
    //  to add sources from which the MIME component will
    //  search for certificates and private keys when decrypting.
    const char *pfxPassword = "myPassword";
    success = mime.AddPfxSourceFile("myCertAndPrivateKey.pfx",pfxPassword);

    //  Display the decrypted MIME:
