Shows how to get the SHA256 hash of a certificate.

LOCAL lnSuccess
LOCAL loBdDer

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

* 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..
lnSuccess = loCert.LoadFromFile("qa_data/certs/cert_test123.cer")
IF (lnSuccess <> 1) THEN
    ? loCert.LastErrorText
    RELEASE loCert
    CANCEL
ENDIF

* Get the binary DER of the certificae, and compute the SHA256 hash:
* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.BinData')
loBdDer = CreateObject('Chilkat.BinData')
loCert.ExportCertDerBd(loBdDer)

* Get the base64 representation of the SHA256 hash.
lcCertHash = loBdDer.GetHash("sha256","base64")

? "Certificate hash in base64 = " + lcCertHash
