Re: Re: Retrieving public key from x and y

I've put a 7z archive with all file I've used into the repository. On the 
CTL I switched the working directory to the extracted one. Then I ran the 
following commands:

nmake /f cryptest.nmake 

cl.exe /nologo /W4 /wd4231 /wd4511 /wd4156 /D_MBCS /Zi /TP /GR /EHsc 
/DNDEBUG /D_NDEBUG /Oi /Oy /O2 /MT /FI sdkddkver.h /FI winapifamily.h /c 
test_Pem.cpp /out:test_pem.obj 

link.exe /nologo /SUBSYSTEM:CONSOLE /DEBUG /DEBUG /OPT:REF /MACHINE:X86 
test_pem.obj cryptlib.lib kernel32.lib /out:test_pem.exe 

After executing test_pem.exe, a .pem file appears with the known result. 

I will try the same again when I'm at home on a different machine, just to 
be sure, nothing is screwed up on my working machine.
