💡 Choice Advice

            

        

          
Which version to choose?

          
SHA-256 is the industry standard for most needs. Use SHA-512 for maximum security.

        

      
        

          
Is SHA-1 still usable?

          
No. SHA-1 has known vulnerabilities. It is recommended to upgrade to the SHA-2 series.
