Is this SHA-256 generator free?

Yes. Unlimited use in the browser.

No. Processing stays in the page.

Both are SHA-2. SHA-512 is larger and can be faster on 64-bit CPUs; SHA-256 is more common in protocols.

SHA-256 hash: online generator

SHA-256 is widely used for integrity checks, blockchain, and general hashing. Paste any string and copy the 64 character hex digest.

Input

SHA-256

Text is hashed as UTF-8 bytes. Output updates live.

SHA-256 outputs 256 bits, written as 64 hex characters.

SHA-256 is part of SHA-2. It is widely used and currently recommended for many uses outside password storage (file integrity, TLS, certificates).

Do not use plain SHA-256 for storing passwords. Use slow password hashes (Argon2, bcrypt, scrypt) with per-user salts.

Is this SHA-256 generator free?: Yes. Unlimited use in the browser.
Do you log my input?: No. Processing stays in the page.
Why 64 hex characters?: 256 bits equals 64 hex digits.
SHA-256 vs SHA-512?: Both are SHA-2. SHA-512 is larger and can be faster on 64-bit CPUs; SHA-256 is more common in protocols.
