This is the PKCS#11 library v188.8.131.52 for the IDPrime .NET cards for 32 and 64 bits versions of all the Windows OS (XP, Vista, W7, W8 & associated Servers). The default smart card crypto architecture in Windows OS is the Base CSP / Minidriver, and the .NET card is supported natively. However several applications don't use Base CSP and use PKCS#11 instead. It is the case of Mozilla Firefox and Thunderbird, Open Office, among others. Release Notes and User's Guide are included in the zip file.
