_LANGUAGE_ sample code showing how to decrypt a .p7m using a .p12 / .pfx certificate w/ private key. JavaScript

var success = false;

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

var crypt = new CkCrypt2();

// Use a digital certificate and private key from a PFX file (.pfx or .p12).
var pfxPath = "myCertAndKey.pfx";
var pfxPassword = "test123";

success = crypt.AddPfxSourceFile(pfxPath,pfxPassword);
if (success !== true) {
    console.log(crypt.LastErrorText);
    return;
}

// Set the  outPath to whatever is appropriate.
// If you are decrypting a PDF, your output might be "out.pdf"...
var inPath = "smime.p7m";
var outPath = "original.txt";

// Indicate that we're doing public key decryption (i.e. PKCS7)
crypt.CryptAlgorithm = "pki";

success = crypt.CkDecryptFile(inPath,outPath);
if (success == false) {
    console.log(crypt.LastErrorText);
    return;
}

console.log("Success.");
