Hash Generator
Compute SHA-1, SHA-256, SHA-384, and SHA-512 hashes of any text.
Your hashes appear here
Type any text and its SHA-1, SHA-256, SHA-384, and SHA-512 digests are computed live — each with a one-click copy button, all in your browser.
Runs entirely in your browserGenerate SHA hashes, locally
Type or paste any text and get its SHA-1, SHA-256, SHA-384, and SHA-512 digests as hexadecimal, updated live. Hashing is one-way: the same input always produces the same fixed-length output, and the output cannot be reversed back to the input — useful for checksums, fingerprints, and integrity checks. All four digests are computed with the browser's built-in Web Crypto, so your text never leaves your device.
Common questions
Which hash algorithms are supported?
SHA-1, SHA-256, SHA-384, and SHA-512 — the algorithms the browser's native Web Crypto (SubtleCrypto) provides. MD5 is intentionally omitted: it is not offered by Web Crypto and is cryptographically broken, so a trustworthy in-browser MD5 would need a bundled library.
What is a hash used for?
Hashes create a fixed-length fingerprint of data. They are used to verify file integrity (checksums), detect changes, index content, and store fingerprints. They are one-way — you cannot recover the original text from the hash.
Is text encoded as UTF-8?
Yes. Your text is encoded as UTF-8 bytes before hashing, so multibyte characters and emoji hash consistently with other UTF-8 based tools.
Should I hash passwords with this?
For storing passwords, a raw SHA hash is not enough — use a slow, salted password hash (bcrypt, scrypt, Argon2) on your server. This tool is for checksums, fingerprints, and general-purpose hashing, not password storage.
Is my text uploaded anywhere?
No. Hashing runs entirely in your browser with the native Web Crypto API. What you type is never sent to a server or stored anywhere.
