RSA Sign utf-8 Byte Representation of String

Demontstrates how to sign the utf-8 byte representation of a string. JavaScript

var success = false;

//  This example requires the Chilkat API to have been previously unlocked.
//  See Global Unlock Sample for sample code.

//  Load an RSA private key for signing.
var privKey = new CkPrivateKey();
success = privKey.LoadEncryptedPemFile("qa_data/pem/rsa_passwd.pem","passwd");
if (success == false) {
    console.log(privKey.LastErrorText);
    return;
}

var rsa = new CkRsa();
success = rsa.UsePrivateKey(privKey);
if (success == false) {
    console.log(rsa.LastErrorText);
    return;
}

var originalData = "This is the string to be hashed an RSA signed.";

//  Indicate that we want the utf-8 byte representation of the string to be signed
rsa.Charset = "utf-8";

//  We want the RSA signature in base64 format
rsa.EncodingMode = "base64";

var sigBase64 = rsa.SignStringENC(originalData,"sha256");
console.log(sigBase64);
