Hashes are one-way; output cannot be reversed.

What a hash is

          
A hash is a one-way fingerprint of data. Small input changes produce very different outputs.

                  
When to use it

          
Use hashes to verify file integrity, create checksums, or compare data quickly.

                  
Hashing vs encryption

          
Hashing is one-way. Encryption is reversible with a key.

              

    
          

        
How to generate a hash

                  
Paste text, choose an algorithm, and copy the hash.

                          
    
                          
  1. Paste your text into the input box.
    2. 
                          
  2. Choose MD5, SHA-1, SHA-256, or SHA-512.
    3. 
                          
  3. Copy the generated hash.

FAQ

                  

            Does this tool upload my data?
            
No. Everything runs locally in your browser.

          

                  

            Which hash should I use?
            
SHA-256 or SHA-512 are recommended for modern use cases.

          

                  

            Is MD5 secure?
            
MD5 is fast but not collision-resistant; avoid it for security.
