Hash Generator | MD5, SHA-1, SHA-256, SHA-384, SHA-512 Online

Generate MD5, SHA-1, SHA-256, SHA-384, and SHA-512 hashes for text or small files. Copy checksums, compare hashes, and keep everything client-side.

No uploads. Everything runs locally in your browser.

Generate hashes for text or small files using MD5, SHA-1, SHA-256, SHA-384, and SHA-512. Compare two inputs to see if their hashes match, and copy results instantly.

Compare mode (same algorithm)
File hash (≤5MB, client-side)

Large files may be slow in-browser; keep uploads small for best experience.

What is a hash?

A hash is a one-way fingerprint of data. Even tiny changes produce a different output, making hashes ideal for integrity checks, signatures, and cache keys.

Hashing vs encryption

Hashing is irreversible and used for verification. Encryption is reversible with a key and used to protect confidentiality. Don’t store passwords with reversible encryption—use salted hashes.

MD5 vs SHA-1 vs SHA-256 vs SHA-512

MD5 and SHA-1 are fast but collision-prone; use them only for non-security checksums. SHA-256 is the modern default for integrity. SHA-384 and SHA-512 offer stronger digests when required by policy or compliance.

How to use this generator

Pick an algorithm, paste text, and Generate. Copy the checksum or compare another input. For small files, select a file and we’ll hash it locally. Clear resets all fields, and Load sample gives you a quick start.

Benefits

  • Fast MD5/SHA hashing in-browser with no uploads.
  • Copy and compare hashes to verify integrity.
  • File hashing for quick checksum checks (≤5MB).
  • Clear guidance on when to use each algorithm.

Privacy-first

Hashing runs entirely in your browser. Text and files aren’t sent to any server, so your checksums stay private.

How to use Hash Generator

  1. Enter or paste text and pick a hashing algorithm.
  2. Click Generate to get the checksum; copy it or compare another input.
  3. Optionally hash a small file client-side and verify integrity.

FAQ

What is a hash?

A one-way fingerprint of data. Small changes produce a different hash, useful for integrity checks and signatures.

Is hashing the same as encryption?

No. Hashing is one-way and irreversible. Encryption is reversible with a key.

Which algorithm should I use?

Use SHA-256 or stronger for integrity. MD5/SHA-1 are fast but not collision-safe for security-critical tasks.

Can I hash files?

Yes, small files up to 5MB are hashed in your browser. Larger files aren’t recommended here.

Is my data sent to a server?

No. Hashing runs locally in your browser; nothing is uploaded.
