      Tip:
       Hash updates in realtime as you type. SHA-256 is recommended for most use cases. MD5 and SHA-1 are legacy and should not be used for security purposes.

Verify Checksum

        

          
Paste the expected checksum from the download page to verify file integrity.

          

            
            
          

          

        

      

    


    

      Tip:
       SHA-256 is the standard for file checksums (used by GitHub, Ubuntu, etc.). Paste the checksum from the download page into the verify field to confirm file integrity.

      Note:
       HMAC (Hash-based Message Authentication Code) verifies both the integrity and authenticity of a message. Unlike plain hashing, HMAC requires a secret key — only parties with the key can generate or verify the signature.
    

    

      Tip:
       HMAC updates in realtime. Keep your secret key confidential — if it leaks, anyone can forge signatures.
