Export a Public Key as XML

Demonstrates the Chilkat PublicKey.GetXml method, which returns the public key in Chilkat XML format. It takes no arguments; the exact representation (for example an RSAPublicKey element) depends on the key type.

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 XML key format comes from the .NET/XML-DSIG world; exporting to it lets you hand a public key to .NET code or a system built around XML signatures. It is the inverse of LoadXml-style loading. Because a public key is not secret, this XML can be shared freely.

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 public key to export.  LoadFromFile inspects the content, so it accepts DER, PEM, XML,
//  JWK, and other supported representations.
var pubKey = new CkPublicKey();
success = pubKey.LoadFromFile("qa_data/public.pem");
if (success == false) {
    console.log(pubKey.LastErrorText);
    return;
}

//  Export the public key in Chilkat XML format.  The representation depends on the key type (for
//  example an RSAPublicKey element for RSA).
var xml = pubKey.GetXml();
if (pubKey.LastMethodSuccess == false) {
    console.log(pubKey.LastErrorText);
    return;
}

console.log(xml);
