FAQ
Is CRC32 a hash like MD5?
CRC32 is a checksum for accidental-error detection, not a cryptographic hash. It is trivially forgeable — use SHA-256 for integrity against attackers.
What is CRC32C used for?
CRC32C (Castagnoli) has hardware acceleration and is used by ext4, iSCSI, LevelDB and cloud storage.
