(JavaScript) Load Signed and/or Encrypted Email and Unwrap Security Layers
The LoadEml method loads an email (.eml file containing the MIME of an email) and automatically unwraps the digital signature and encryption security layers. A program can then examine the properties of the email object to see what was unwrapped.
var success = false;
var email = new CkEmail();
// Provide PFX/.p12 files for any certs+keys needed for decryption.
// Signature verification does not need anything extra.
// (Also, Chilkat will automatically find and use pre-installed certs + private keys needed for decryption
// on a Windows system.)
success = email.AddPfxSourceFile("/pfxFiles/certs_and_keys_1.pfx","pfxPassword1");
if (success !== true) {
console.log(email.LastErrorText);
return;
}
success = email.AddPfxSourceFile("/pfxFiles/certs_and_keys_2.pfx","pfxPassword2");
if (success !== true) {
console.log(email.LastErrorText);
return;
}
// ...
// Load a potentially signed and/or encrypted email.
success = email.LoadEml("someDir/someEmail.eml");
// If the email was signed and/or encrypted, it was "unwrapped", i.e.
// the email is already decrypted and in a state as if it were never signed or encrypted.
// You may check to see if the email was received encrypted or signed, and if so,
// whether it was successfully unwrapped and who signed or encrypted it:
if (email.ReceivedEncrypted == true) {
console.log("This email was encrypted.");
if (email.Decrypted == true) {
console.log("This email was successfully decrypted. It was encrypted by:");
console.log(email.EncryptedBy);
}
else {
console.log("This email was not decrypted.");
}
}
if (email.ReceivedSigned == true) {
console.log("This email was signed.");
if (email.SignaturesValid == true) {
console.log("The signature was verified. It was signed by:");
console.log(email.SignedBy);
}
else {
console.log("The signature verification failed.");
}
}
// At this point, the contents of the email, including attachments, can be accessed normally..
