// Load a certificate object with a certificate.
// The certificate object could have come from any source,
// or perhaps was obtained from another Chilkat function.
// The source does not matter.  What matters is that we have
// a cert object loaded with the certificate..

// Get the binary DER of the certificae, and compute the SHA256 hash:

loCert.ExportCertDerBd(loBdDer)

// Get the base64 representation of the SHA256 hash.

? "Certificate hash in base64 = " + lcCertHash
