–––Generate SHA hashes online
Type any text to instantly generate its SHA-1, SHA-256 and SHA-512 hashes. Hashes are one-way checksums used to verify data integrity, store password fingerprints and compare files.
Secure and private
Hashing uses your browser's built-in Web Crypto API, so your text is processed locally and never sent to a server.
Why no MD5?
Browsers don't provide MD5 natively and it's considered cryptographically broken. Prefer SHA-256 for checksums and integrity checks. Need a random id instead? Try the UUID generator.
Frequently asked questions
Which hash algorithms are supported?
SHA-1, SHA-256 and SHA-512, generated with your browser’s built-in Web Crypto API.
Why is MD5 not included?
Browsers do not provide MD5 natively, and it is considered insecure. SHA-256 is recommended for checksums and integrity checks.
Is my text sent anywhere?
No. Hashing happens locally in your browser and nothing is uploaded.
