About this tool
A hash is a fixed-length output derived from any text, used to verify data integrity. A UUID is a unique random identifier that works as a database key.
The tool uses the browser Web Crypto API, and your text is never sent anywhere.
Frequently asked questions
Can SHA-256 be reversed?
No, hash functions are one-way.
Is a UUID unique?
