PKCS11 Find all Public Keys

See more PKCS11 Examples

Demonstrates how to list all public keys on an HSM.

Note: This example requires Chilkat v9.5.0.96 or later.

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

; Note: Chilkat's PKCS11 implementation runs on Windows, Linux, Mac OS X, and other supported operating systems.

$oPkcs11 = ObjCreate("Chilkat.Pkcs11")

; Use the PKCS11 driver (.dll, .so, .dylib) for your particular HSM.
; (The format of the path will change with the operating system.  Obviously, "C:/" is not used on non-Windows systems.

; Establish a logged-on session. (We can typically skip the login by passing an empty PIN if only needing to list public keys)
; Use your actual PIN here, or an empty string to skip login.

$bSuccess = $oPkcs11.QuickSession($iUserType,$sPin)

; Note: To find public keys, we need a session, but it doesn't necessarily need to be logged-on.
