Hash de arquivo

O que é Hash de arquivo?

File hash generates checksums (MD5, SHA-256, etc.) to verify file integrity and identity. Detect tampering or duplicates.

Hashing is computed locally. Files never leave your device.

Quando usar?

  • Integrity check: Verify downloads match originals
  • Deduplication: Find duplicate files by hash
  • Security: Confirm file authenticity
  • Backup verification: Ensure backups are correct

Vantagens

  • Multiple algorithms: MD5, SHA-1, SHA-256, etc.
  • Fast: Quick local computation
  • Privacy: No upload
  • Batch: Hash multiple files

Perguntas frequentes

A unique fingerprint of file content. Same content = same hash.

SHA-256 is recommended. MD5 is quick but not cryptographically secure.

Como usar

  1. Upload: Add file(s) to hash
  2. Select algorithm: Choose MD5, SHA-256, etc.
  3. Compute: Generate hash values
  4. Copy: Use hash for verification

Dica: Use SHA-256 when security matters.
