This is old cryptography. This book should not be quite as bad for its readers as Schneier's Applied Cryptography (which includes many ciphers which were known to be broken at the time, with little hint of that fact in the text), but it's still old-fashioned. E.g. - Chapter 7 "block ciphers" doesn't even mention CTR mode, but does mention CFB and OFB. Modern cryptosystems all use CTR mode, and no new system I'm aware of uses CFB or OFB. -…

I'm an aspiring cryptographer and this book is hands-down one of the best references for applied cryptography out there today. Don't let the date fool you; cryptography is an area where maturity is well appreciated. It's also fantastic that the whole thing is available online, but believe me when I say that the text is well worth the price if you ever find yourself needing a good cryptography reference. Some other good references are Introduction to Modern Cryptography by Katz…
