How to use Hash Generator
- Select a SHA algorithm.
- Enter the text to hash.
- Run the tool and copy the hexadecimal digest.
Example and important notes
Hashing the same UTF-8 text with the same algorithm always produces the same digest.
- A hash is one-way, but weak passwords can still be guessed.
- Use a dedicated password-hashing function for stored passwords.
Frequently asked questions
Which algorithm should I use?
SHA-256 is a common general-purpose choice. Avoid SHA-1 for security-sensitive integrity checks.
Is the text uploaded?
No. The browser Web Crypto API calculates the digest locally.
