Using Bcrypt with Spring Security

Password security is a popular topic. The most basic tenant of password security is to have no password at all. Wait, what? That’s right, no password should be stored in your database, ever. Instead, store it as a hash, along with the salt, and throw the original password away. Ask 10 different developers, and I’ll bet that MD5 would be offered as the most popular solution for this problem. Though, if you’ve explored the linked content, you’ll have undoubtedly noticed that Bcrypt is mentioned more than a few times.

“Bcrypt is a cross platform file encryption utility. Encrypted files are portable across all supported operating systems and processors. Passphrases must be between 8 and 56 characters and are hashed internally to a 448 bit key. However, all characters supplied are significant. The stronger your passphrase, the more secure your data.”

For us Java developers, there’s jBCrypt. It is an “implementation of OpenBSD’s Blowfish password hashing code” and offers a rather simple API. A quick web search yields a bit of information on using jBCrypt itself, but nothing on integrating it with the Spring Framework. Given that this is a topic of interest to me, I’ve put together a simple, yet comprehensive example web application to demonstrate an integration of jBCrypt, Spring MVC, Spring Security and Hibernate for hashing user passwords. There are three areas I’ve focused on in this example, user creation, user authentication and changing the user’s password. Read More »

Red5 + Hibernate Revisited

It’s hard to believe that I wrote the first version of this tutorial almost a year and a half ago. That’s too long to wait for an update in my opinion and is much needed in this case. My apologies for not tending to the garden sooner. While the original article illustrated a simple method for integrating Red5[1] and Hibernate[2], by today’s standards it’s design is overly verbose and somewhat out of fashion. Not to mention the 3 major components used in this tutorial have all gone through major revisions. The primary goal for this iteration was simplification of the code as well as the XML configuration elements and results in a smaller code footprint. This is a big win in my book. Read More »

This tutorial has been updated. Please check out the new post.

Having followed the growth of the Red5 Media Server[1] from it’s fledgling 0.3 days, I’ve become fairly familiar with its offerings. One of the most frequently asked questions on the Red5 mailing list pertains to database connectivity for user authentication and application security. I’ll attempt to tackle one solution here using Hibernate[2], an object/relational persistence framework. Read More »
