For anyone wondering, or teaching about DES, or interested in perverse
uses for spreadsheets, I have created an "Illustrated DES spreadsheet".
This is a vanilla spreadsheet (no VB or anything exotic) and should
work on many excel and excel workalikes.

Acknowledgements for this work goes to J. Orlin Grabbe for his The DES
Algorithm Illustrated which can be found at
http://www.aci.net/kalliste/des.htm
I have also stole many tricks including how to do XOR in generic excel
which I can not find again to give proper credit. I haven't run this
through the FIPS 140-2 level 1 test suite (but this could easily be
certified :-)
Anyone interested in making one for MD-5?
Enjoy
jim
