Load a Private Key from XML Text

Demonstrates the Chilkat PrivateKey.LoadXml method, which loads a private key from XML text. The only argument is the XML string. Supported roots include RSAKeyValue, DSAKeyValue, ECCKeyValue, and Ed25519KeyValue.

Background: XML key representations such as RSAKeyValue come from the .NET/XML-DSIG world, where keys are exchanged as XML elements. This loads that form — the inverse of GetXml — which is handy for interoperating with .NET code or systems built around XML signatures. It is a plaintext format, so protect the XML like any unencrypted key material.

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.

//  Demonstrates the PrivateKey.LoadXml method, which loads a private key from XML text.  The only
//  argument is the XML string.  Supported roots include RSAKeyValue, DSAKeyValue, ECCKeyValue,

var privKey = new CkPrivateKey();

//  The XML text of a private key (for example as produced by GetXml).
var xmlText = "<RSAKeyValue><Modulus>...</Modulus><Exponent>AQAB</Exponent>...</RSAKeyValue>";

success = privKey.LoadXml(xmlText);
if (success == false) {
    console.log(privKey.LastErrorText);
    return;
}

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