Shows how to get the SHA256 hash of a certificate. PowerBuilder

integer li_rc
integer li_Success

// 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..
li_Success = loo_Cert.LoadFromFile("qa_data/certs/cert_test123.cer")
if li_Success <> 1 then
    Write-Debug loo_Cert.LastErrorText

// Get the binary DER of the certificae, and compute the SHA256 hash:
loo_BdDer = create oleobject
li_rc = loo_BdDer.ConnectToNewObject("Chilkat.BinData")

loo_Cert.ExportCertDerBd(loo_BdDer)

// Get the base64 representation of the SHA256 hash.

Write-Debug "Certificate hash in base64 = " + ls_CertHash
