CkPython Requires Chilkat v11.0.0+

PKCS11 Export Public Key from HSM

See more PKCS11 Examples

Demonstrates how to export a public key from a smartcard or token. CkPython

import chilkat

success = False

#  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.

pkcs11 = chilkat.CkPkcs11()

#  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.
pkcs11.put_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 working with public keys)
#  Use your actual PIN here, or an empty string to skip login.
pin = "0000"
userType = 1
success = pkcs11.QuickSession(userType,pin)
if (success == False):
    print(pkcs11.lastErrorText())
    sys.exit()

#  Get the handle of the public key we wish to export.
#  You can find public keys in many different ways.
#  This example will search for a public key by label.

#  Provide a template to find a PKCS11 object.
jsonTemplate = chilkat.CkJsonObject()

#  Find the public key with the label "Belgium eHealth".
jsonTemplate.UpdateString("class","public_key")
jsonTemplate.UpdateString("label","Belgium eHealth")

pubKeyHandle = pkcs11.FindObject(jsonTemplate)
if (pubKeyHandle == 0):
    print(pkcs11.lastErrorText())
    sys.exit()

#  Export to a Chilkat public key object.
pubKey = chilkat.CkPublicKey()
success = pkcs11.ExportPublicKey(pubKeyHandle,pubKey)
if (success == False):
    print(pkcs11.lastErrorText())
    sys.exit()

#  Get the public key as PKCS8 PEM.
print(pubKey.getPem(False))
