How to use
Enter any text and click Compute Hashes. All hashing runs locally in your browser using the native Web Crypto API — your text never leaves your device.
Note
SHA hashes are one-way. Use SHA-256 or stronger for integrity checks. These are not password-storage hashes.
Frequently asked questions
Which algorithm should I choose?
SHA-256 is the modern default. SHA-1 only for checking old legacy values.
Same text always gives same hash?
Yes, hashing is deterministic, so identical input always matches.
Can a hash be reversed?
No, hashes are one-way. That is why they are used for integrity checks.
