What is MD5?

            
MD5 (Message-Digest Algorithm 5) is a widely used cryptographic hash function that produces a 128-bit hash value, used for ensuring information integrity.

  • The result is generated in real-time; click copy to use it.

            


            

              
Security Note

              

        

          
Is MD5 secure?

          
For highly sensitive data like passwords, MD5 is no longer secure. It is recommended to use SHA-256 or stronger algorithms, combined with 'salting'.
