Figure … WebFeb 22, 2016 · CRC32 is a checksum that derives a 32 bit long digest, that is used, for instance, to check if a compressed file was damaged while being transferred. However, the fact that it generates a 32 bit long digest led to the believe that it can be used as a cryptographic hash for integrity control.
