Hash Generator
SHA-1, SHA-256, SHA-384 and SHA-512 — computed in your browser.
What is a hash used for?
A hash is a fixed-length “fingerprint” of data. The same input always produces the same hash, and changing even one character produces a completely different result. That makes hashes ideal for checksums (verifying a download wasn’t corrupted), integrity checks, and as building blocks in security systems.
These hashes are computed with your browser’s built-in Web Crypto engine, so your text never leaves your device. Note that hashing is one-way: you cannot turn a hash back into the original text. For random secrets, use the password generator.
Hash FAQ
What is a hash?
A hash is a fixed-length fingerprint of some data. The same input always gives the same hash, and even a tiny change produces a completely different result.
Can a hash be reversed?
No. Cryptographic hashes are one-way, so you cannot recover the original text from the hash.
