Web20 sep. 2024 · The longest commonly used checksum is CRC-32, which has a 32 bit or 4 byte output. The shortest commonly used hashes are 128 bits or 16 bytes. There are almost 8e28 more potential values for a 128 bit value compared to 32 bits. Checksums are therefore far more prone to collisions than hashes. rcw window tinting
