hash generator

How to generate a hash online

A hash maps input to a fixed-size digest. Same input → same hash. Useful for checksums and integrity.

Which algorithm

Prefer SHA-256. SHA-1 and MD5 are legacy: fine for non-critical checksums, not modern security.

Pick an algorithm, paste text, copy hex. Runs locally via Web Crypto (+ local MD5).

Don’t store passwords as plain SHA-256. Use Argon2/bcrypt/scrypt with salt server-side.

Compare vendor-published digests to verify downloads. One different bit changes the hash.

HMAC adds a key. A bare hash doesn’t authenticate origin without a shared secret.

Which algorithm?

Prefer SHA-256. MD5/SHA-1 are legacy.

Is hashing local?

Yes. Text is not uploaded.

For passwords?

Don’t store passwords as plain hashes; use Argon2/bcrypt server-side.
