Sample code showing how to open a PKCS11 session and then later close it.

Note: This example requires Chilkat v9.5.0.88 or later.

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 = chilkat2.Pkcs11()

# Set your shared lib path -- either a full path to the DLL, .so, or .dylib,
# or just the filename if the driver is in a location that can be automatically found. (Such as in C:\Windows\System32)
pkcs11.SharedLibPath = "ShuttleCsp11_3003.dll"

# Starting in Chilkat v9.5.0.96, there is a shorter way to establish
# a PKCS11 session with login.
# The QuickSession method was added in v9.5.0.96 and is the equivalent of 
# calling Initialize, OpenSession, and Login.  

success = pkcs11.Initialize()
if (success == False):
    print(pkcs11.LastErrorText)
    sys.exit()

# Pass -1 for the slotID to open a session on the first non-empty slot.
slotID = -1

# Open a read/write session.
readWrite = True
success = pkcs11.OpenSession(slotID,readWrite)
if (success == False):
    print(pkcs11.LastErrorText)
    sys.exit()

# Do whatever is needed...
# ...
# ...

# When finished, close the session.
# It is important to close the session (memory leaks will occur if the session is not properly closed).

success = pkcs11.CloseSession()
if (success == False):
    print(pkcs11.LastErrorText)
    sys.exit()

print("PKCS11 session successfully opened and closed.")
