* Starting in v9.5.0.49, all Chilkat classes can be unlocked at once at the beginning of a program
* by calling UnlockBundle.  It requires a Bundle unlock code.
* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.Global')
loChilkatGlob = CreateObject('Chilkat.Global')
lnSuccess = loChilkatGlob.UnlockBundle("Anything for 30-day trial.")
IF (lnSuccess <> 1) THEN
    ? loChilkatGlob.LastErrorText
    RELEASE loChilkatGlob
    CANCEL
ENDIF

* The Chilkat PEM class was introduced in v9.5.0.49.  
* It requires the bundle to be unlocked, as shown above.
* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.Pem')
loPem = CreateObject('Chilkat.Pem')

* Load the .p7b from a file.
lnSuccess = loPem.LoadP7bFile("../myCertFiles/myP7b.p7b")
IF (lnSuccess <> 1) THEN
    ? loPem.LastErrorText
    RELEASE loChilkatGlob
    RELEASE loPem
    CANCEL
ENDIF

* Note: If the app already has the p7b loaded in memory, the LoadP7b method
* may be called instead.  (see the online reference documentation)

* Iterate over the certificates.
