Is there a risk of leakage if the website saves MD5 or other methods of encrypting the password?

The original password only the user knows, the website also does not know.

And this encryption algorithm plus the site's own password string, so even if the database is compromised, the password is actually useless, neither can be used to log in, nor can be used for multiple sites of the general, even if the user each site used to be the same user name and password.

If the salt is strong enough and there is no leakage. It should be okay.

I mean if some of the key data, in the upload time has been encrypted, not to mention the hacker, is the site itself does not know the customer's information, because the public encryption algorithm, and users never upload their own password, always only users know. Brute force crack in the case of public encryption algorithm, it is very difficult to crack, in addition to the user to set a very simple password this situation is no solution, if others can guess the password, any security technology is powerless.

The user name, and some of the text classes need to be displayed in the browser content, is not encrypted, because these things need to be public ...

Your understanding is right, individual MD5 is not safe (you can search "online MD5"), this also look at the complexity of user's password. If your site saves the user's original password, then the company's programmers can see the password, and the general user is accustomed to all sites with the same user name and password. Do not say that the data is exported, is a perverted programmer, take the site's user name and password to the large site to try, an estimated 10 must have 7 can log in.
Again despise csdn! I changed all the registered websites.
