Load a Private Key from a PKCS #1 File

Demonstrates the Chilkat PrivateKey.LoadPkcs1File method, which loads a private key from a file. The only argument is the file path. Despite the historical PKCS #1 name, it accepts any supported unencrypted private-key representation.

Note: The file path is relative to the application's current working directory. Absolute paths may also be used. Supply the path to your own key file.

Background: PKCS #1 is the older, RSA-specific key format — the BEGIN RSA PRIVATE KEY block still common from OpenSSL. This method reads it, and like the other content-inspecting loaders it also accepts other unencrypted representations, so it is forgiving of what is actually in the file. For unknown or mixed formats, prefer LoadAnyFormatFile.

Note

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.

var privKey = new CkPrivateKey();

success = privKey.LoadPkcs1File("qa_data/private_pkcs1.pem");
if (success == false) {
    console.log(privKey.LastErrorText);
    return;
}

console.log("Loaded a " + privKey.KeyType + " private key.");
