Load P7B and Iterate Certificates

See more PEM Examples

Demonstrates how to load a .p7b containing one or more certificates access each of them. B4X

Dim success As Boolean = False

'  This example assumes the Chilkat API to have been previously unlocked.
'  See Global Unlock Sample for sample code.

success = False

'  The Chilkat PEM class was introduced in v9.5.0.49.  
'  It requires the bundle to be unlocked, as shown above.
Dim pem As ChilkatPem
pem.Initialize

'  Load the .p7b from a file.
success = pem.LoadP7bFile("../myCertFiles/myP7b.p7b")
If success <> True Then
    Log(pem.LastErrorText)
    Return
End If


'  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.
Dim numCerts As Int = pem.NumCerts
Dim i As Int = 0

Do While i < numCerts

    Dim cert As ChilkatCert = pem.GetCert(i)
