What is SHA-256?

SHA-256 is part of the SHA-2 family and produces a 256-bit (64 hex character) hash. It is collision-resistant and widely trusted — used in TLS certificates, blockchains, file integrity checks, and digital signatures. It's the recommended choice for general-purpose secure hashing.

Frequently Asked Questions

Is SHA-256 secure?

Yes — SHA-256 is a current, trusted standard with no practical collision attacks, suitable for integrity checks and signatures.

Can I hash a password with it directly?

For passwords, use a slow, salted password hash (bcrypt, scrypt, or Argon2) rather than a raw SHA-256, which is too fast for that purpose.

Is it free and private?

Yes — it's 100% free with no signup, and everything runs locally in your browser, so your data is never uploaded to a server.
