The original code is not mine, I'm simply making it 64-bit friendly and
removing some compiler warnings where possible.

dcpcrypt2.pas(660,9) Error: Array type required
You are the second person to recommend something like this and every
time I get compiler errors. I am using 64-bit FPC 2.4.0-rc1 under Linux.
But yes, your code is indeed more readable. :-)

I'm not using 32-bit processors. That's the whole reason for the
modifications to DCPCrypt code - getting it 64-bit compatible.
