About this tool
SHA-256 Generator computes SHA-256 digests — the modern default for file checksums, data integrity, and fingerprinting. Developers hash API payloads, verify downloads against published digests, and fingerprint content with it daily.
Digests are computed with the browser's native Web Crypto implementation: fast, correct, and fully local. Output is lowercase hex, ready to copy or compare.
How to use
- Type text or drop a file into the uploader.
- The SHA-256 digest computes automatically.
- Copy the hex hash or compare it against a published checksum.
Frequently asked questions
File integrity verification, content fingerprinting, Git-like addressing, and as a building block in digital signatures and blockchains.
Plain SHA-256 is too fast for password storage — attackers can brute-force billions of guesses per second. Passwords need slow, salted hashes like bcrypt, scrypt, or Argon2.
Hash the downloaded file here and compare the result character-for-character with the checksum the publisher provides. Any difference means the file is corrupt or tampered with.
No — hashing happens entirely in your browser.
