In your case (as you can read in my second previous comment) you need to append the following four bytes:
ef, ‘)’, f3 and b1.
Obviously you should use the ASCII code of ‘)’ and the character represented by the hexadecimal notation ‘ef’.

Do i have to input sumtin in the document to make the CRC change.

if __name__ == ‘__main__’:
crc32 = Crc32Provider()
print “We take a message which has the hash 0xdeadbeaf”
# Thanks to path:

crc32._hash = crc32.xorOut ^ NumberFromHexadecimal(’deadbeaf’)
print “Required patch to make the hash 0×12345678:”
p = crc32.patch(NumberFromHexadecimal(’12345678′))
print p
print “Applying patch, resulting hash:”
crc32.update(p)
print NumberToHexadecimal(crc32.hash)
print “It works ^_^”

You replace the current CRC32 where it says deadbeaf in this column
crc32._hash = crc32.xorOut ^ NumberFromHexadecimal(’deadbeaf’)
and you replace desired CRC32 where it says 12345678 in this column
p = crc32.patch(NumberFromHexadecimal(’12345678′))

then you save it ..
then you run it and then what .. sorry that im noob .. ^^

At the bottom of the file you see the code that is run when you directly execute crc.py. I hope for you it’s a plain CRC hash. In that case replace deadbeaf with yours (2ca91a04). And replace the desired hash 12345678 with yours. (c8fd18cb).

Run the script via python crc.py and it should output the patching bytes. It looks a bit like a mess because it aren’t all printable ASCII characters. This are the repr-ered contents: '\xef)\xf3\xb1'. So, append the bytes ef, ‘)’, f3, b1 to your file and you should be fine.

But i just got into scripts and codes and i would like someone to explain how to change the CRC32 hash to the hash you desire ..

but could u plz explain it to me coz im a noobie and theres about 100 ppl counting on me to figure it out .. (and im not joking)

The method I describe works by calculating the four bytes that you need to append to any given file to change the hash to the one you desire. Just modify the Python or Java example to suit your needs.

I was just wondering if anyone could help me out here. As you all know when you edit your file the CRC32 changes and you can right click>properties>filehashes and see how its changed.

But what i want to know is; If i had a CRC32 value in my head and i wanted to change the CRC32 into this valuem, what would i have to do to edit it.

EG Tips.xml >right-click>properties>file hashes and it has

2CA91A04
but maybe i wanted to change it to
C8FD18CB

How would i do that .. please i am desperate i need to know.
