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.

integer li_rc
integer li_Success
oleobject loo_Pfx
string ls_Password
integer li_NumKeys
oleobject loo_PrivKey
integer i

li_Success = 0

loo_Pfx = create oleobject
li_rc = loo_Pfx.ConnectToNewObject("Chilkat.Pfx")
if li_rc < 0 then
    destroy loo_Pfx
    MessageBox("Error","Connecting to COM object failed")
    return
end if

//  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.
ls_Password = "myPfxPassword"
li_Success = loo_Pfx.LoadPfxFile("qa_data/identity.pfx",ls_Password)
if li_Success = 0 then
    Write-Debug loo_Pfx.LastErrorText
    destroy loo_Pfx
    return
end if

//  Enumerate the private keys in the PFX by zero-based index.  Valid indexes are less than
//  NumPrivateKeys.
li_NumKeys = loo_Pfx.NumPrivateKeys
loo_PrivKey = create oleobject
li_rc = loo_PrivKey.ConnectToNewObject("Chilkat.PrivateKey")

for i = 0 to li_NumKeys - 1
    li_Success = loo_Pfx.PrivateKeyAt(i,loo_PrivKey)
    if li_Success = 0 then
        Write-Debug loo_Pfx.LastErrorText
        destroy loo_Pfx
        destroy loo_PrivKey
        return
    end if

    Write-Debug "Private key " + string(i) + ": " + loo_PrivKey.KeyType + " (" + string(loo_PrivKey.BitLength) + " bits)"
