* See Global Unlock Sample for sample code.
* This example will generate a secp256r1 ECDSA key for the CSR.

loCsr = CreateObject('Chilkat.Csr')
* Add common CSR fields:
loCsr.CommonName = "mysubdomain.mydomain.com"
loCsr.Country = "GB"
loCsr.State = "Yorks"
loCsr.Locality = "York"
loCsr.Company = "Internet Widgits Pty Ltd"
loCsr.EmailAddress = "support@mydomain.com"
* Add the following 1.2.840.113549.1.9.14 extensionRequest
* Note: The easiest way to know the content and format of the XML to be added is to examine
* a pre-existing CSR with the same desired extensionRequest. You can use Chilkat to
* get the extensionRequest from an existing CSR.
* Here is a sample extension request:
* <?xml version="1.0" encoding="utf-8"?>
* <set>
* <sequence>
* <sequence>
* <oid>1.3.6.1.4.1.311.20.2</oid>
* <asnOctets>
* <printable>ZATCA-Code-Signing</printable>
* </asnOctets>
* </sequence>
* <sequence>
* <oid>2.5.29.17</oid>
* <asnOctets>
* <sequence>
* <contextSpecific tag="4" constructed="1">
* <sequence>
* <set>
* <sequence>

* </sequence>
* </set>
* </sequence>
* </contextSpecific>
* </sequence>
* </asnOctets>
* </sequence>
