About Checksums

  • • Checksums verify file integrity and detect corruption or tampering
  • • MD5 is fast but not cryptographically secure
  • • SHA-256 is recommended for security-sensitive verification
  • • Always verify downloads from untrusted sources

File Checksums - Technische Details

Checksums are hash values used to verify file integrity. Compare the hash of a downloaded file with the expected value to ensure it wasn't corrupted or tampered with during transfer.
