First of all, MD5 is not an encryption algorithm, but a signature algorithm. Hey, how many Chinese people have been poisoned?

In addition, as long as it is an encryption algorithm that can be implemented by software, js can be used. It is just a matter of efficiency.

General

asymmetric algorithm, use The resources are huge, so js is rarely available.

As for the symmetric encryption algorithm..., since js is visible to the user,... it is the same as no encryption.

This is why truly high-security websites will not choose to use js for encryption, but choose to use https protocol.

Once again, MD5 is not an encryption algorithm, so it is no longer within the above range
