...ary. This will give you an offset and you used it to update the addresses. > [I'm always curious as to how these type of designs cope with someone modifying the checksumming code itself, but that's another problem - or is this one of these things where the checksum is stored in special hardwareprotected memory?]. For now, I store it into an special place. My first solution for my problem was to used some temporary file but this is highly impractical. Maybe I can create a temporary section into the binary but I didn’t find a lot of information about it. Thanks, Johan > -- > Mats > &...

I will try to explain better what I do. The main goal behind this is to verify that a part of code is not modified by someone else (it is an integrity check). To do this, I create in IR a function who take 2 parameters, a begin and an end value. This function perform an hash over the code area (from begin to end) and return it. At first, I don’t know the addresses and the hash value so I put
