About CRC32

CRC32 (Cyclic Redundancy Check) is a fast error-detecting code commonly used to detect accidental changes to raw data. It produces a 32-bit checksum that can verify data integrity but is not suitable for cryptographic purposes.

  • Used in ZIP files, PNG images, Ethernet, and many file formats
  • Detects all single-bit errors and most burst errors
  • Not collision-resistant - collisions can be easily crafted
  • Much faster than cryptographic hash functions
  • Use MD5 or SHA for security-sensitive checksums
