Linux Driver support for the CoolKey and CAC products. CoolKeys are part of a complete PKI solution that provides smart card login, single sign-on, secure messaging, and secure email access. In the complete solution, users are issued CoolKeys by their employer, ISP, bank, or other parties. When the user plugs the keys in for the first time, the keys are automatically provisioned with certificates, keys, and a PIN, unique for that user by the Red Hat Certificate System. Once the CoolKey is provisioned, the user can take the key to any system and use it to login (authenticate), send and receive signed and encrypted email, or participate in secure messaging or IRC communication. CoolKeys are based on JavaCard 1.2.
