Save a Private Key as a Traditional PEM File

Demonstrates the Chilkat PrivateKey.SavePemFile method, which saves the key as unencrypted PEM, preferring a traditional algorithm-specific representation (for example RSA PRIVATE KEY). The only argument is the destination path.

Note: The file paths are relative to the application's current working directory. Absolute paths may also be used. Supply the paths appropriate to your own environment.

Background: The file-writing form of GetPkcs1Pem, producing the legacy per-algorithm PEM that some older software requires. Prefer SavePkcs8PemFile for modern interoperability; use this when a consumer specifically needs the traditional layout. The PEM is unencrypted.

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.

JavaScript

var success = false;

//  Load a private key to export.
var privKey = new CkPrivateKey();
success = privKey.LoadPemFile("qa_data/private.pem");
if (success == false) {
    console.log(privKey.LastErrorText);
    return;
}

//  Save as unencrypted PEM, preferring the traditional algorithm-specific representation (for
//  example "RSA PRIVATE KEY" for RSA).
success = privKey.SavePemFile("qa_output/private.pem");
if (success == false) {
    console.log(privKey.LastErrorText);
    return;
}

console.log("Saved.");
