If you're curious about how my diagrams and animations evolved over time, a brief summary of the previous versions can be seen here. I'm very pleased at all the support and advice I was given as I crafted and revised these images. If you are still using any of these old versions in your own presentations, while I applaud your dedication and early adoption of this style of diagram, I would request that you not use the old versions anymore. Please visit the main page for the current versions. Thanks!   - Deviant

 

Version One

The first diagrams I ever made were based more or less directly on the images in the MIT Guide to Lockpicking. They contained no colored fill and lacked detail elements in many respects. These images were never used publicly in any presentation.

 

Version Two

My initial presentations at ShmooCon and DEFCON were based around these images. They incorporated color and were the start of my use of GIF animation in order to depict how lockpicking is performed. Diagrams based on these images were later featured at events such as HackCon, HackInTheBox, ToorCon, ShakaCon, SecTor, and many others.

 

Version Three

In April of 2009 i began using revised diagrams. These incorporated greater color depth and shading in order to convey three dimensional pieces and the individual elements were re-shaped to better reflect exactly where the pieces of a lock contact one another, how the key rides in, variations in key pin height, etc. While this was a marked improvement, the pieces were still not to scale in many respects.

 

Version Four

In the Spring of 2010 i began work on my first book, to be published by Syngress. In the process, i began fully developing new images that i had been tinkering with since March of that year. Based around detailed caliper measurements made on a Kwikset-style lock, these diagrams properly reflected essentially all elements of pins, plug, housing, keys, etc. Everything was 100% to scale, and even greater attention was paid to factors of color, shading, and crisp lines. These images started being seen in my presentations in late May of 2010 and have been used ever since.
