Hash Generator
Hash pasted text with SHA-256, SHA-384, or SHA-512 in your browser.
Cryptographic hashes in your browser
A hash turns any input into a fixed-length fingerprint — useful for verifying file integrity, comparing values, and generating deterministic identifiers. This generator computes SHA-256, SHA-384, and SHA-512 hashes of pasted text instantly.
It uses the browser’s built-in Web Crypto (SubtleCrypto), so the hashing is real and standards-based, not a hand-rolled approximation. Paste text, pick the algorithm, and copy the digest — handy for checksums and debugging without any command-line tools.
Deterministic, kept local
The same input always produces the same hash, which is what makes it useful for integrity checks and comparisons. Hashing runs in your browser, so inputs stay private.
Frequently asked questions
Which hash algorithms can I use?
SHA-256, SHA-384, and SHA-512, calculated with your browser's built-in Web Crypto API.
Why is there no MD5?
Browsers' Web Crypto API does not offer MD5 because it is broken for security uses. See the MD5 checksum explainer.
Can I hash a password with this?
You can see the SHA hash, but plain SHA is not suitable for storing passwords. Use bcrypt, scrypt, or Argon2 in your application.
