Enumerate Private Keys in a PFX

See more PFX/P12 Examples

Demonstrates Pfx.PrivateKeyAt, which copies the private key at a zero-based index into a PrivateKey object. The example enumerates all private keys in the PFX.

The file path is relative to the application's current working directory. An absolute path may also be used. Supply the path appropriate to your own environment.

Dim success As Boolean
success = False

Dim pfx As New Chilkat.Pfx

//  The file path is relative to the application's current working directory.  An absolute path
//  may also be used.  Supply the path appropriate to your own environment.
//  The PFX password should come from a secure source rather than being hard-coded.
Dim password As String
password = "myPfxPassword"
success = pfx.LoadPfxFile("qa_data/identity.pfx",password)
If (success = False) Then
    System.DebugLog(pfx.LastErrorText)
    Return
End If

//  Enumerate the private keys in the PFX by zero-based index.  Valid indexes are less than
//  NumPrivateKeys.
Dim numKeys As Int32
numKeys = pfx.NumPrivateKeys
Dim privKey As New Chilkat.PrivateKey
Dim i As Int32
For i = 0 To numKeys - 1
    success = pfx.PrivateKeyAt(i,privKey)
    If (success = False) Then
        System.DebugLog(pfx.LastErrorText)
        Return
    End If

    System.DebugLog("Private key " + Str(i) + ": " + privKey.KeyType + " (" + Str(privKey.BitLength) + " bits)")
