What Is the Hash Generator?
The Hash Generator turns text into a hexadecimal fingerprint using SHA-1, SHA-256, SHA-384, or SHA-512. Hashes update live for exactly the text in the box. Clearing the box clears the results.
Hashing runs in your browser. A hash is a one-way fingerprint, not an encrypted message you can decrypt later.
How to Use the Hash Generator
- Type or paste your text into Input text.
- Read the results for each supported algorithm as they update automatically.
- Copy the hash for the algorithm you need.
- Clear the box to remove the results and start again.
Spaces, punctuation, and line breaks all count, so keep the text unchanged when comparing two hashes.
Useful Ways to Compare Text
- Compare two versions of a short text using the same algorithm.
- Create sample checksums for documentation or test data.
- See how changing a single character changes the fingerprint.
- Compare the lengths of SHA-1, SHA-256, SHA-384, and SHA-512 results.
Use sample text when learning, rather than entering real passwords or other secrets.
Tips for Choosing and Comparing Hashes
- Use the same algorithm on both sides of a comparison.
- Preserve whitespace and line endings when an exact match matters.
- Prefer modern algorithms such as SHA-256 for new work. SHA-1 is unsuitable for new security designs.
- Use a dedicated password-hashing method for password storage, not plain SHA.
This tool hashes pasted text rather than uploaded files.

Frequently asked questions
Which algorithms can I use?
SHA-1, SHA-256, SHA-384, and SHA-512.
Do hashes update as I type?
Yes. Results update live for exactly the text in the box, and clearing the box clears the results.
Why does adding a space change the hash?
Every character counts, including spaces and line breaks. Even a small change produces a different fingerprint.
Is my text sent away for hashing?
No. Hashing runs in your browser.
