Possible to change the CRC of a file with autoit?

Topic. "Possible to change the CRC of a file with autoit?"

I am curios if there is any possible way to change the CRC of a file with auto it.

EDIT:

May I add the file I want to change a CRC of is a .DLL , and even 1byte changed in the DLL would make it different CRC. (If it was possible to hex edit a line with auto it this would do the trick, but I am not sure how to do it.)

EDIT2:

To be more clear, I want to search the hex string in a "DLL" (like you would in a hex editor) "3333" , I then want to replace that "3333", with "4444". Hence, I hex edited the DLL, giving it a different CRC.

Not natively. You would need to call a DLL written in another language (such as C++).

Sorry.

I highly doubt that. I've seen and herd of Hex edits by Lary but can't seem to find them. I am fairly sure it is possible to hex edit a file in auto it, I am just not sure how to do it.

EDIT:

Updated first post..

Why are you trying to change the checksum?

To have a different CRC?... Hence the hex editing that needs to take place..

Search for +FileWrite +Binary

Maybe add +FileOpen

Should get you places...:)

I already did a lot of searching for things, and was unable to find the info I needed, and what I did find I could not understand. Thats why I am posting for help and possible some example code...

I have yet to find any non-malicious reason for editing the CRC of a .dll file. Especially by someone who doesn't understand binary files... what exactly are trying to use AutoIt to do?
