Load a Private Key from PEM Text

Demonstrates the Chilkat PrivateKey.LoadPem method, which loads a private key from PEM text. The only argument is the PEM string. It has no password argument, so it cannot load an encrypted PEM — use LoadEncryptedPem for that.

Background: PEM is the Base64 text format (delimited by -----BEGIN----- lines) that most tooling uses for keys. This method is for the plain, unencrypted case where the key material sits in the clear inside the PEM — convenient, but it means the file itself is the only thing protecting the key. When the PEM is password-protected (a BEGIN ENCRYPTED PRIVATE KEY block or a legacy encrypted header), reach for the Encrypted loader instead.

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();

//  The PEM text of an unencrypted private key.
var pemText = "-----BEGIN PRIVATE KEY-----\nMIIEvAIBADANBgkq...\n-----END PRIVATE KEY-----";

success = privKey.LoadPem(pemText);
if (success == false) {
    console.log(privKey.LastErrorText);
    return;
}

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