What is the difference between Protection Kit MPI and Smarx OS Protection Kit? Which one should I use?
Both are libraries to access the CRYPTO-BOX. Besides automatic implementation via AutoCrypt (for Windows) both libraries support implementation into sourcecode via API calls in all common development environments. MPI is a Windows-library, which supports all CRYPTO-BOX types (CRYPTO-BOX USB, Parallel and Serial) over common API calls. SmarxOS supports the CRYPTO-BOX USB only, thereby utilizing the full capabilities of the CRYPTO-BOX USB (protecting different applications with only one CRYPTO-BOX, protect up to 10 applications in networks with only one CRYPTO-BOX, Multi-Platform-Support: Windows32/64, Linux32/64, Mac OS*). MPI is recommended if you want to implement the CRYPTO-BOX Parallel (either in conjunction with a USB or by itself). If you want to use the CRYPTO-BOX USB only, and/or you need support for Linux and Mac OS*, SmarxOS is the best choice.
