LinuxForums.org is a free help and support forum for Linux distribution software and computer hardware. It currently has more than 200,000 registered members. The site was established in 2001 and changed ownership in 2008 and is now owned by MAS Media Inc.

Using salted MD5 password hashes is a bad idea because…well, MD5 is very fast, so an attacker can try billions of password combinations per second.
