Thoughts on password encryption & database/website security


Recommended Posts

I am building a new site for my brother and was wondering what the users out here thought about the many options for password security in a MYSQL database.  Is using md5 &/or sha1 with some scheme of salting enough?  I am also curious about AES & BLOWFISH.  How are these implemented?  Also, are php code files on a server subject to the same security issues as an SQL database? (In other words, can hackers get at these files to view the code which might include schemes for salting?)

 

Thanks to all,

Newbie Tom

 

Edit (KP): No need to shout ;)

I thought this recorded webinar was extremely informative on the subject:

He talks about the different algorithms, the best way to encrypt a password, etc.
