What is Adler-32?

Adler-32 is a fast checksum algorithm that outputs a 32-bit value (usually 8 hexadecimal characters). It is designed for accidental error detection, not for cryptographic security.

Key points:

  • Fast and deterministic: The same input always returns the same output
  • Integrity check: Useful for transfer or storage corruption detection
  • Not cryptographic: Do not use for passwords, signatures, or anti-tampering

Common uses:

  • File transfer checks
  • Archive/package verification
  • Lightweight integrity checks
