Introduction

Due to the latest row of high profile websites being compromised and parts of the password hashes being published here's a quick crash course on storing passwords "securely", for those that want a quick heads up. In this case I'd define securely as "Offering a suitable time window of resistance against recovery after being compromised". I will keep this post short and sweet and use links where possible for those interested in more information.

Update:  After reading this blog post read the interview of Brian Krebs with Thomas H. Ptacek on the matter. 
Update: Wrong bcrypt link fixed, update the Year bcrypt was presented.

 

Details

Putting things into perspective, below are the most common forms of storing passwords (order from worse to best) :

• Storing credentials in clear text
• Storing credentials using a hash (MD5, SHA, SHA256) 
• Storing credentials using unique salt per entry and a hash (MD5, SHA, SHA256)
• Storing credentials using bit/key stretching mechanisms or being overall time expensive (PBKDF2, bcrypt, scrypt, phpass)
