PKCS11 Discover Readers and Smart Cards / Tokens

Example showing how to discover the readers (slots) and smart cards and tokens available through a vendor's PKCS11 Cryptoki module.Chilkat Lua Downloads

-- See Global Unlock Sample for sample code.
-- Note: Chilkat's PKCS11 implementation runs on Windows, Linux, Mac OS X, and other supported operating systems.

end
-- Call Discover to discover what's available.
-- Indicate that we only want to return slots (readers) where tokens (smart cards) are present.
-- (If the device is a USB token, such as an ePass300Auto, then by definition it has a "token" present.)
