Pourquoi c'est le Meilleur Générateur de Hash en Ligne

Plusieurs Algorithmes

Generate MD5, SHA-1, SHA-256 and SHA-512 hashes simultaneously with a single input, no need to run separately.

Hachage de Fichiers

Upload any file and compute its checksum to verify file integrity — useful for downloads, backups and security audits.

Comparaison de Hash

Paste two hashes side by side to instantly verify if they match — useful for confirming download integrity.

Traitement Côté Client

All hashing runs in your browser using the Web Crypto API. Files and text are never uploaded to a server.

Questions Fréquentes

What is the difference between MD5 and SHA-256?

MD5 produces a 128-bit hash and is fast but cryptographically broken — use it only for checksums, not security. SHA-256 is part of the SHA-2 family, produces a 256-bit hash, and is considered secure for most purposes.

Can I use this to hash passwords?

No. MD5 and SHA-256 are fast hashes not suitable for passwords. Use a slow password hashing algorithm like bcrypt, scrypt, or Argon2 for password storage.

How do I verify a file download with a hash?

Hash the downloaded file using the same algorithm (usually SHA-256 or MD5) and compare the result to the checksum provided by the source. They must match exactly.
