Set a PFX Safe-Bag Attribute

See more PFX/P12 Examples

Demonstrates Pfx.SetSafeBagAttr, which sets a safe-bag attribute on a private key or certificate inside 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 Long
success = 0

Dim pfx As New ChilkatPfx

'  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 = 0) Then
    Debug.Print pfx.LastErrorText
    Exit Sub
End If

'  Set a safe-bag attribute on an item inside the PFX.  Safe-bag attributes are metadata attached to
'  an item in the container; they do not change the certificate or key material itself.  The 1st
'  argument is 1 for a private key or 0 for a certificate, and the 2nd is the zero-based
'  index within that collection.
Dim bForPrivateKey As Long
bForPrivateKey = 1

'  friendlyName is a text-valued attribute, so the encoding argument is ignored (pass an empty
'  string).  For binary attributes such as localKeyId, the encoding names the value's representation.
success = pfx.SetSafeBagAttr(bForPrivateKey,0,"friendlyName","My Identity","")
If (success = 0) Then
    Debug.Print pfx.LastErrorText
    Exit Sub
End If

Debug.Print "Safe-bag attribute set."
