I have a executable of C++ Qt project and I want to assign a checksum to it for documentation purpose so that I add can details like
Software Version : 1.5
Checksum : 0xBd3429A
The checksum should change whenever i update my project like add new code or remove bugs or add files or remove files.
I know about md5 and sha1 and other standard hash algorithms which i can run commands and calculate the checksum but what i am looking for is smaller hashes like 4 to 6 bytes at most. Any help would be deeply appreciated.
