What Is This Tool?

        
The Hash Generator computes a cryptographic or checksum digest of any text you type, using MD5, SHA-1, or SHA-256. Hashes are one-way fingerprints commonly used to verify data integrity, compare files, or generate deterministic identifiers. All computation happens locally in your browser — nothing you type is ever uploaded or stored.

      


      

        
How to Use

        

          
1
Type or paste the text you want to hash into the input box.

          
2
Choose an algorithm: MD5, SHA-1, or SHA-256.

          
3
The hash updates automatically, or click Generate to recompute.

          
4
Copy the resulting hash for use elsewhere.

Frequently Asked Questions

        
Is my text uploaded anywhere?
No. All hashing happens locally in your browser using JavaScript and the Web Crypto API. Nothing is sent to a server.

        
Is MD5 secure?
No. MD5 is considered cryptographically broken and should not be used for security purposes. It's included here for checksums, legacy compatibility, and learning purposes only.

        
Is SHA-1 secure?
SHA-1 is also considered weak against determined attackers and is deprecated for security-sensitive use. Prefer SHA-256 or stronger when security matters.

        
Which algorithm should I use?
For anything security-related, use SHA-256. Use MD5 or SHA-1 only when you need compatibility with an existing system that requires them.

        
Why does the hash change on every keystroke?
The tool recomputes the hash live as you type, with a short debounce, so you always see the hash of your current input.

        
Can I hash a file?
This tool only hashes text you type or paste. File uploads are intentionally not supported since JsonCherry tools never send your data anywhere.
