Public Key Cryptography Standard (PKCS) Number 11 specifies an API for interfacing with cryptographic tokens.  These cryptographic tokens are usually seperate hardware devices that do not provide direct access to the keying materials under normal use -- instead they directly perform the cryptographic operations on the hardware module.  This provides additional security and can be used for off-loading CPU intensive operations to specialized hardware.

package require pki
package require pki::pkcs11

set handle [pki::pkcs11::loadmodule /usr/lib/pkcs11/libcackey.so]

pki::pkcs11::login $handle $slotId 123456

set slots [pki::pkcs11::listslots $handle]
set slotId [lindex $slots 0 0]

set certs [pki::pkcs11::listcerts $handle $slotId]
set cert [lindex $certs 0]
pki::pkcs11::login $handle $slotId 123456

set plain "TestMsg"

set cipher [pki::encrypt -binary -pub -- $plain $cert]
set check  [pki::decrypt -binary -priv -- $cipher $cert]

puts "Plain: $plain"
puts "Check: $check"
