' Some tests using the FirmaSAT .NET interface.
' *
' * Requires `FirmaSAT` to be installed on your system: available from <https://www.cryptosys.net/firmasat/>.
' * Add a reference to `diFirmaSatNet.dll` installed in `C:\Program Files (x86)\FirmaSAT`.
' *
' * Test files are in `FirmaSATtestfiles.zip`. These must be in the CWD.
' *
' * This is a Console Application written for target .NET Framework 2.0 and above.
