Acknowledgments

Creating this book has been quite the journey. Ever since we embarked on the project and started putting the outline together, we had a feeling it was going to take a lot more sweat than we could have ever been prepared for. We were more right than we realized at the time, and it’s with great pleasure that we are finally able to write this part, thanking the many people who helped make it happen. We can’t possibly name you all here, so accept our humble thanks even if your name isn’t listed here explicitly.

First off, this book would have never happened without the input and encouragement of the OAuth Working Group in the IETF and the larger OAuth and open standards communities. In particular, John Bradley and Hannes Tschofenig each provided invaluable input to the text at various points. Ian Glazer, William Dennis, Brian Campbell, Dick Hardt, Eve Maler, Mike Jones, and many others in the community encouraged us to create the book and helped provide important information to the internet. Aaron Parecki provided us space on oauth.net to not only talk about the book but also publish topical articles, including an early form of what became chapter 13. And special thanks to Ian for contributing the foreword and endorsing our work.

This book would literally not exist without the help and input from the team from Manning Publications. Our fantastic team of editors and support staff included Michael Stephens, Erin Twohey, Nicole Butterfield, Candace Gillhoolley, Karen Miller, Rebecca Rinehart, Ana Romac, and especially our amazing editor Jennifer Stout. Thanks to Ivan Kirkpatrick, Dennis Sellinger, and David Fombella Pombal for making sure the technical bits made sense. A big thanks to everyone who took a chance and preordered the book as a MEAP; the early feedback we got from you was vital in making this the best book we could make it.

We would also like to thank our peer reviewers who read the manuscript at various stages of its development and provided invaluable feedback along the way: Alessandro Campeis, Darko Bozhinovski, Gianluigi Spagnuolo, Gregor Zurowski, John Guthrie, Jorge Bo, Richard Meinsen, Thomas O’Rourke, and Travis Nelson.

Incomparable thanks are due to my coauthor, Antonio Sanso. His security and cryptographic expertise far outstrips anything I could dream of achieving, and it’s been an honor to work with him. Starting the book was his idea in the first place, and the whole project has been a collaborative effort.

Thanks to my friends Mark Sherman and Dave Shepherd, both of whom successfully published tech books before I first set words to the page. Their existence served to remind me that there was a light at the end of the tunnel, and their experience in navigating the publishing world was a great help. Thanks to John Brooks, Tristan Lewis, and Steve Moore, whom I was able to bounce ideas and phrases off of, even if they didn’t always realize I was doing it at the time.

Many thanks to my clients over the last year for putting up with me disappearing at random times to go off and write. Thanks are especially due to Debbie Bucci and Paul Grassi, as their fantastic work programs have helped give me the direct experience needed to ground this book in the real world.

I can’t possibly express enough thanks to my friend and colleague, Sarah Squire. She originally turned me on to the Node.js frameworks used in the exercises throughout the book, and I believe that, thanks to a trip to an office store, she has the distinction of owning the first printed version of this book. Overall, her encouragement, support, critique, and enthusiasm for this project has been without compare, and I doubt that the book would have really happened without her.

Finally, but perhaps most importantly, a sincere and deep thank you to my entire family. The patience of my wife, Debbie, and my kids, Lucien, Genevieve, and Xavier, has been incredible. Between late nights and seemingly endless weekends with me locked up in my office, just out of reach, I’m sure they started to wonder if I’d ever come out, but now I’m glad to say there should be a whole lot more time to play Legos.

Working on this book has been quite a ride, and it’s with great delight and satisfaction that I write this part. In the end, as with everything, it’s the journey and not the destination that matters. My contribution to this book could not be possible without the help of many people surrounding me.

I would like to thank my employer, Adobe Systems, and my managers Michael Marth and Philipp Suter for giving me the green light to work on this book.

OAuth is a widespread protocol written in a collaborative way by many people under the IETF umbrella. Some of those people are the brightest minds in the security community. We had the privilege to have some extremely useful comments on the work-in-progress draft by John Bradley, Hannes Tschofenig and William Denniss.

It is incredible how friendship can have an influence on someone’s life. For this reason, I’d like to thank, in no particular order: Elia Florio for being a constant source of inspiration; Damien Antipa for being so patient while explaining the most arcane part of Javascript and CSS; Francesco Mari, who introduced me to the beautiful world of Node.js and tirelessly listened my endless complains; Joel Richard for helping me with the magic of Apache Cordova; Alexis Tessier, the most talented designer I ever met; and Ian Boston for proofreading.

And last but not least, Justin Richer, who has been the best coauthor I could ever hope for. You rock, Justin!

But I can’t finish without a special thank you to the people I love.

To my parents. They always encouraged me to pursue studying, without putting any pressure on me, even if they didn’t study themselves. Their support was unique. To my brother and sister who also encouraged me, especially in the early stage of my university time.

And of course, the biggest thank you goes to my fiancée (soon wife) Yolanda, who supports and continuously encourages me on everything I do. Finally, to Santiago, my son, who helps me remember every single day how beautiful life is. I love you.
