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

# Chilkat recommends the following free tool for interactively examining the contents of your smart card
# through the ScMinidriver interface:  MGTEK Tool for Minidriver enabled Smart Cards

# Let's first look at our smart card..
# Here's the view of the card we happen to be using: a Gemalto (Thales) IDPrime MD T=0 smart card.



set scmd [new_CkScMinidriver]

# First we need to acquire a context to the smart card in the reader where it is inserted.
# Reader names (smart card readers or USB tokens) can be discovered
# via List Readers or Find Smart Cards
set readerName "Alcor Micro USB Smart Card Reader 0"
set success [CkScMinidriver_AcquireContext $scmd $readerName]
if {$success == 0} then {
    puts [CkScMinidriver_lastErrorText $scmd]
    delete_CkScMinidriver $scmd
    exit
}

# If successful, the name of the currently inserted smart card is available:
puts "Card name: [CkScMinidriver_cardName $scmd]"

# To delete the contents of a key container, we'll need to be PIN authenticated..

# For more details about smart card PIN authentication, see the Smart Card PIN Authentication Example
set pinId "user"
set retval [CkScMinidriver_PinAuthenticate $scmd $pinId "0000"]
if {$retval != 0} then {
    puts "PIN Authentication failed."
    CkScMinidriver_DeleteContext $scmd
    delete_CkScMinidriver $scmd
    exit
}

# Let's delete the contents of key container #7
# This deletes both keys (signature key and "key exchange" key) that might be present in the key container.
# (It is not possible to delete just one or the other.)
set success [CkScMinidriver_DeleteKeyContainer $scmd 7]
if {$success == 0} then {
    puts [CkScMinidriver_lastErrorText $scmd]
    CkScMinidriver_DeleteContext $scmd
    delete_CkScMinidriver $scmd
    exit
}
