(Visual FoxPro) 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.

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.Pkcs11')
loPkcs11 = CreateObject('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.
loPkcs11.SharedLibPath = "C:/Program Files (x86)/Gemalto/IDGo 800 PKCS#11/IDPrimePKCS1164.dll"

* 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.
lcPin = "0000"
lnUserType = 1
lnSuccess = loPkcs11.QuickSession(lnUserType,lcPin)
IF (lnSuccess = 0) THEN
    ? loPkcs11.LastErrorText
    RELEASE loPkcs11
    CANCEL
ENDIF

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

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.JsonObject')
loJson = CreateObject('Chilkat.JsonObject')
loJson.EmitCompact = 0

lnSuccess = loPkcs11.FindAllKeys("public",loJson)
IF (lnSuccess = 0) THEN
    ? loPkcs11.LastErrorText
    RELEASE loPkcs11
    RELEASE loJson
    CANCEL
ENDIF
