load ./chilkat.dll

# 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.

set pkcs11 [new_CkPkcs11]

# 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)
CkPkcs11_put_SharedLibPath $pkcs11 "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.  

set success [CkPkcs11_Initialize $pkcs11]
if {$success == 0} then {
    puts [CkPkcs11_lastErrorText $pkcs11]
    delete_CkPkcs11 $pkcs11
    exit
}

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

# Open a read/write session.
set readWrite 1
set success [CkPkcs11_OpenSession $pkcs11 $slotID $readWrite]
if {$success == 0} then {
    puts [CkPkcs11_lastErrorText $pkcs11]
    delete_CkPkcs11 $pkcs11
    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).

set success [CkPkcs11_CloseSession $pkcs11]
if {$success == 0} then {
    puts [CkPkcs11_lastErrorText $pkcs11]
    delete_CkPkcs11 $pkcs11
    exit
}

puts "PKCS11 session successfully opened and closed."

delete_CkPkcs11 $pkcs11
