Fill in the fields to see the result
The processed output appears here after you run the tool.
Generated output
Web Crypto
The browser calculates SHA-256 and SHA-512 through the Web Crypto API.
Local operation
The input text does not need to leave the page to generate a hash.
Security note
Hashes are useful fingerprints, but they are not a substitute for encryption or password hashing systems.
Common use cases
- Create test checksums.
- Compare text values.
- Document expected hashes in examples.
Limitations
- This version hashes text, not files.
- Hashing is not encryption.
- Do not use a raw hash as a password storage system.
Frequently asked questions
Is the text uploaded?
No. Hashing runs locally in your browser.
Does it generate MD5?
No. This tool focuses on SHA-256 and SHA-512.
Can I recover the original text from a hash?
No. A hash is one-way for practical use.
