Storing Passwords

Yes, it's that minefield again. I'm building an AJAX database interface which uses maria/mysql logins instead of keeping a bunch of its own private logins, to try and keep it simple.

The thorny bit is, of course, the passwords. Doing this requires it to remember passwords between sessions, not merely hashes but reversibly-encrypted passwords. I think I've built something like "ssh-agent" for databases, which keeps a key without leaving it wide-open to the world, but I want your feedback on it.

When the PHP session begins, the server generates a pair of 16-digit strings. One is kept in the server-side PHP session and never given to the user, the other is kept in a client-side cookie and never stored on the server. The concatenation of both strings is used to ENCODE() the password before storing it. It also records and validates your session ID and IP address, so someone can't steal the cookie and pretend to be you. Only the conjunction of a valid cookie with a valid login decrypts a valid password.

It sounds strong enough to me but encryption is not my forte. Are there any giant holes in this scheme?

PASSWORD-GORILLA(1)					      General Commands Manual					       PASSWORD-GORILLA(1)

NAME

       password-gorilla -- a password manager

SYNOPSIS

       password-gorilla

DESCRIPTION

       The  Password  Gorilla  helps  you  manage your logins. It stores all your user names and passwords, along with login information and other
       notes, in a securely encrypted file. A single "master password" is used to protect the file. This way, you only need to remember the single
       master password, instead of the many logins that you use.

       If  you	want to log in to a service or Web site, the Password Gorilla copies your user name and password to the clipboard, so that you can
       easily paste it into your Web browser or other application. Because the password does not appear on the screen, Password Gorilla is safe to
       use in the presence of others.

       The convenience of Password Gorilla allows you to choose different, non-intuitive passwords for each service. An integrated random password
       generator can provide one-time passwords, tunable to various services' policies.

FILES

       The program creates a configuration file .gorillarc in the homedirectory of the user.
