Whether you're verifying a file's integrity, generating a fingerprint for comparison, or just need a quick checksum, this tool computes MD5, SHA-1, SHA-256, and SHA-512 hashes from any text instantly, all calculated locally in your browser.
How to use the hash generator tool
- 1
Type or paste text
Add the text you want to hash.
- 2
Read the hashes
MD5, SHA-1, SHA-256, and SHA-512 hashes are calculated instantly, side by side.
- 3
Copy the one you need
Each hash has its own copy button.
Common use cases
Verify file or text integrity
Compare a hash you generate against a published checksum to confirm content matches.
Generate a quick fingerprint
Create a short, unique fingerprint for a piece of text for comparison or deduplication.
Learn how hashing works
See how the same input always produces the same hash, and how different algorithms produce very different-looking output.
Frequently asked questions
SHA-256 is the modern standard for most integrity and security purposes. MD5 and SHA-1 are still common for legacy compatibility checks but are considered cryptographically broken for security-sensitive use.
