SHA-256 Generator
Compute SHA-256 hashes using the browser's Web Crypto API.
Input
SHA-256 (64 hex chars)
(hash appears here)About this tool
SHA-256 produces a 256-bit (64 hex character) hash. Industry-standard for file checksums, blockchain, and many security applications. The hash is computed by the browser's built-in Web Crypto - no third-party JS needed.
FAQs
Is SHA-256 a good choice for password hashing?
Plain SHA-256 is fast - too fast for passwords. Use bcrypt, scrypt or Argon2, which are intentionally slow and salted.
What's the difference between SHA-256 and SHA-2?
SHA-256 is one variant of the SHA-2 family. Other variants in the family include SHA-224, SHA-384, SHA-512.
Is the hash deterministic?
Yes - the same input always produces the same hash. That's the whole point.
