I have a CD with an encrypted database (DBF) in which the data of some columns appears as strange characters and cannot be read by any DBF viewer or in Excel. The only program that show this dB correctly is
the EXE files that comes with the CD. But the searching mechanism of this EXE is poor and I cannot filter the data as I would like.

I got a decompiler that shows me the line codes of this EXE (created in Fox Pro 6) but as I am not good in programming, I don't know what I can do to begin decrypting the database, that's why I am asking you for help.

Can I decrypt the DBF with the line codes in my hand? If yes, how? What should I look for?

Can the line codes contain the algorithm? I identify a code as being a password in the file start.fxp... but I do not know if it would help ( password = 'XXXXX')

What would be the better (and easier) option? Try do decrypt the database or modify the searching mecanism on the exe file?

Thank you very much beforehand for your help.
