Hi, recently I'm come across some checksum that I cant figure it out, so I used QuickBms crc scanner, and its give me the correct algorithm for it and it was:
Code:
0x01800063  "32 0 0 37 0 0"

its worked perfectly
but problem is I need to be able generate this checksum in my own program (because structure of the file I'm currently working on is a bit complex and quickbms cant handle importing for it)
I wonder how can I use the algorithm that quickbms give me in my own program..?
its possible to create a dll from quickBMS crc Engine? I think it can be very useful

@zigzag: You can check quickbms documentation for crc reference and using of QUICKBMS_CRC_TABLE for your needs. Also, 37 algorithm would be adler32 and you can find its implementation in src\libs\libbsc\adler32 of source code.

Ah, you need quickbms 0.11 for that QUICKBMS_CRC_TABLE feature and using -V at command-line to make it visible when using the command: print "%QUICKBMS_CRC_TABLE%"
