@ indomit :

Lot's of tedious equation solving and a bit of number theory. Good one ! :)

I found the key that satisfies all conditions but you program reports an OVERFLOW error !!

Sent you a PM.

The key file should be written as BINARY not TEXT.

That's where I was wrong. Corrected now and got the good-boy !!

Will post solution soon.
