Um, if i’m not mistaking, this book has been available for free online for years.
I agree that this book is great, though.

I think Bruce’s main reason was to announce it publicly. Indeed the book (as many of Menezes’ works) has been available online for quite a long time… but if you do not really plow in this field, you probably would not know.

Now it is out in the open. Good to have someone else — read Bruce — promoting this very good book. Rather heavy reading though 🙂

Not to forget that you blogged about this less then a month ago.

Well, OK, that was about an online course in which one of the first links was pointing at this book.

Any chance of seeing “Beyond Fear” made available under some kind of non-commercial Creative Commons license? It’s a royal pain to obtain in UK bookshops, and I can only afford so many hardback copies to lend and give to friends. I want all my friends, colleagues, political representatives etc. to read it!

I don’t understand why people feel the need to point out that a post is old news or whatnot; regardless of the validity of the re-post. Unless you just love the attention you draw to yourself, what does it matter? Perhaps some of us have a heavy work-load and don’t have time to follow every link of every post or read every security blog out there.

@Bryan: Bruce said that the book is “now available…legitimately.” This implies that those of us who were aware of this site years ago may not have gotten it legitimately. By pointing out that this is old news, we are clarifying that it’s been legitimate all along.

I second the nomination for Mr. Schneier to provide free on-line copies of all his books.

“is now available online — legitimately. ”

“legitimately” refers to the fact that this is the DHS-approved version.

There are some subtle edits to bring it in line with current national-security best practices.

For example, the section on unbreakable encryption now mentions ROT13 instead of OTP.

If you have downloaded a previous, unapproved version, then it is your patriotic duty to get the update.

hahahaha, oh Bruce…you get away with this one for free because of how useful this autographed picture of you is for wiping harddrives.

Good to see the book online. But I think it was online earlier…

Also, I saw an online version of “Applied Cryptography, Second Edition: Protocols, Algorthms, and Source Code in C” years before. It is still somewhere in my archieves.

World class books. both.
These are some rare peices of work which you will buy the original printed copy even though you have read some free(or pirated) online version.

Not to be confused with this handbook pertaining to Applied Cryptography, of course:

Yes. When I saw the news I thought “Well Good on you, Bruce!”

Bruce Schneier December 12, 2007 2:36 AM


“Applied Cryptography” is, basically, owned by my publisher: Wiley. I don’t get to decide if the text goes online or not.

That being said, the text was distributed electronically as part of a CD-ROM thingy some years ago, and there are almost always illicit electronic copies of the book floating around the internet. Google for it.

Bruce, your book, AC, great, got in paper. Ever going to be a AC2, like after NIST Hash contest?
Would be great to read about all the updates and new whatevers, especially trusted computing, and how much a PITA real world crypto is, OS issues, hard drives rememberance, etc… Nice to be able to show the suits a ‘legitimate’ source of reputable info….Otherwise its just the internet…
Enjoy your blog.

Here is part of the copyright notice — Permission is granted to retrieve, print and store a single copy of this chapter for personal use. This permission does not extend to binding multiple chapters of the book, … .

So do I get to copy only one chapter? Or do I apply the copyright sequentially to each? (Of course, being careful not to bind them.)
