See more Certificates Examples

This example requires Chilkat v9.5.0.87 or greater. It uses a Windows-only function named LoadFromSmartcard.

This example loads a certificate specified by its subject common name (CN part of the Subject). The LoadFromSmartcard method will examine the connected smart cards and USB tokens and will find and load the certificate having the specified CN.

    // This example requires the Chilkat API to have been previously unlocked.

    Set ComSmartCardPin Of hoCert To "12345678"

    // To load the certificate specified by CN, pass the string "CN=<subjectCN>".  For example:

    Get ComSubjectDN Of hoCert To sTemp1
    Get ComSerialNumber Of hoCert To sTemp2
