Security a€“ Should I delete my ‘wp-config.php’

I am not agree about security in wp-config.php.
In wp-config.php, our passwords are always visible for the admins and, for example, if an error about Apache/PHP configuration occurs, code of php pages can be visible for visitors. It’s very dangerous.

I think There should be a solution for that, right?

“In wp-config.php, our passwords are always visible for the admins “

Which admins ?
If you mean domain admins then their power to disrupt your site is much wider than a password.

Apache/PHP error – possibly I suppose. But in the two years I’ve been hanging around here and the two years in which tens of thousands of WP blogs have been used I have not yet seen it reported.

‘very dangerous’ ? I’d say it’s a risk but a very very tiny one. Having a poor/weak password is worse.

Yes, I know that an Apache/PHP error is not very probable but it’s possible, no?

I’m searching the way to connect with mysql passing a md5 password but I don’t know if it’s possible.

Maybe, I am a little crazy (xD) but I think the password (and protect it) is the most important thing is a website. The other things in a website or blog are public and I can do a backup.
