BalfBlog is making a big change today that will change a lot of installations. Luckily there is a new plugin included by default with all installations that fixes this.
The fix I speak of is moving from using MD5 in any hashing algorithms at all. I was interested in finding out whether or not MD5 was a preferred choice to SHA1 for a short URL and came across a page in which the write manages to produce two images which are distinctly different yet the manage to produce the same MD5 value causing a collision. Not good.
As a result I have decided to change from MD5 being used to generate hashed URLs to SHA which has a much lower chance of a collision than MD5 does. For more information on creating collisions (and it's a very interesting article) look to here:
