Demonstrates how to load a Certificate Signing Request (CSR) and examine the contents.

Note: This example requires Chilkat v9.5.0.65 or greater.

C#

bool success = false;

//  Note: Requires Chilkat v9.5.0.65 or greater.

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

Chilkat.Csr csr = new Chilkat.Csr();

//  Load a CSR PEM file.  The file should contain content that looks like this:
