Department of Defense Common Access Card PKCS#11 Provider

CACKey is a PKCS#11 compliant library that provides access to the cryptographic and certificate functions US Goverment Smartcards (cards that comply to Government Smart Card Interoperability Specification v2.1). It supports all versions of the Department of Defense Common Access Card (CAC) and US Government Personal Identity Verification (PIV) cards (starting with release 0.7.0).

It requires a PC/SC interface to the smartcard. This can be provided by PCSC-Lite, the SunRay PCSC-Lite, or the Microsoft Windows Native PC/SC Driver.
