File Verification Tool

Verify file integrity and authenticity using cryptographic checksums. Choose specific algorithms or calculate all supported hashes for comprehensive verification.

Choose Operation Mode

Maximum file size: 50MB. Files are never stored on our servers.
SHA-256 is recommended for general use. Select "All" for comprehensive verification.

How It Works

  • Calculate Mode: Generate checksums using selected algorithms
  • Verify Mode: Compare file against expected checksum
  • Auto-detect: Automatically identifies hash algorithm by length
  • Secure: Files processed in memory, never stored
  • Private: All processing happens locally on our servers

Recommended Algorithms

SHA-256

Most widely used, perfect for general purposes

SHA-512

Higher security, ideal for sensitive files

BLAKE2b

Fastest modern algorithm with high security

SHA3-256/512

Latest standard, maximum future-proofing
