' This example 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.Http")
set http = CreateObject("Chilkat.Http")

' Check the revocation status of the SSL server certificate for chilkatsoft.com
status = http.OcspCheck("chilkatsoft.com",443)

outFile.WriteLine("chilkatsoft.com status = " & status)

' The status can have 4 values:
' -1: Unable to check because of an error.
'  0: Good
'  1: Revoked
'  2: Unknown

If (status < 0) Then
    outFile.WriteLine(http.LastErrorText)
End If

' Now check the status for a revoked server certificate.
status = http.OcspCheck("revoked.badssl.com",443)

outFile.WriteLine("revoked.badssl.com status = " & status)

outFile.Close
