LOCAL loSt
LOCAL i
LOCAL lnNumSans

* Note: Requires Chilkat v9.5.0.91 or greater.

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

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.Csr')
loCsr = CreateObject('Chilkat.Csr')

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