How PGP Works The Basics of cryptography. When Julius Caesar sent messages to hisgenerals, he didn t trust his messengers. What is cryptography? http://www.pgpi.org/doc/pgpintro/
Extractions: The following text is taken from chapter 1 of the document Introduction to Cryptography http://access.adobe.com/ and then manually edited by hand. When Julius Caesar sent messages to his generals, he didn't trust his messengers. So he replaced every A in his messages with a D, every B with an E, and so on through the alphabet. Only someone who knew the "shift by 3" rule could decipher his messages. And so we begin. Data that can be read and understood without any special measures is called plaintext or cleartext. The method of disguising plaintext in such a way as to hide its substance is called encryption. Encrypting plaintext results in unreadable gibberish called ciphertext. You use encryption to ensure that information is hidden from anyone for whom it is not intended, even those who can see the encrypted data. The process of reverting ciphertext to its original plaintext is called decryption Figure 1-1 illustrates this process.

CyberLaw (tm) -- CRYPTOGRAPHY & SPEECH cryptography SPEECH. Dr. Daniel Bernstein has some ideas about cryptography,the art and science of keeping messages secure, that he wants to share. http://www.cyberlaw.com/cylw1095.html
Extractions: by Jonathan Rosenoer "Without cryptography, what people send via computers is the electronic equivalent of a postcards, open to view by many people while the message is in transit. With cryptography, people can put both messages and money into electronic 'envelopes,' secure in the knowledge that what they send is not accessible to anyone except the intended recipient. ... Continued development of cryptography promises to make it possible for the worldwide computer Internet to offer private, secure and protected communication among billions of people worldwide." While a Ph.D. candidate in Mathematics at the University of California at Berkeley, Daniel Bernstein worked in the field of cryptography and developed an "encryption algorithm or recipe which he calls 'Snuffle.'" He described Snuffle in English and in mathematical equations, as well as in the "C" computer programming language (Snuffle.c and Unsnuffle.c). Bernstein wants to publish his cryptographic ideas and research results "as part of the normal process of academic, scientific and political exchange of ideas and information," and, in particular, in "text journals as well as in an online discussion group about the science of cryptography, called sci.crypt. According to Bernstein, "[a]ware of the [Government's] civil and criminal restrictions on cryptography export, [he] asked the Office of Defense Trade Controls ("OTDC"), an arm of the State Department, to find out whether he could publish his ideas." He told OTDC that he wanted to export the document "The Snuffle Encryption System," and the Snuffle.c and Unsnuffle.c source files.

Cryptography And Steganography cryptography and Steganography. Codegroup. Utility which encodes and allthis. JavaScrypt BrowserBased cryptography. A collection http://www.fourmilab.ch/nav/topics/crypto.html
Extractions: Utility which encodes and decodes binary files into five-letter code groups just like secret agents use. Handy for sending small binary messages by telephone, radio, or telegraph. Quantum mechanics teaches us that, at the deepest level, uncertainty rules the universe: there are things we cannot predict, even in principle. HotBits harnesses this fundamental uncertainty of nature to generate truly random bits, unlike the pseudorandom sequences created by an algorithm on a computer. Along the way, you'll find a discussion of the hardware and software used to generate the random bytes comprehensive enough to build your own, and peek under the hood of quantum mechanics to see why the data are genuinely random, and some of the implications of all this. A collection of Web pages and programs in the JavaScript language perform military-grade encryption (256 bit secret key AES entirely within your Web browser you needn't download nor install any software, and nothing is sent to any Web site when you encrypt or decrypt a message. You can download the page source and JavaScript programs to your own computer and use them even when not connected to the Internet.

Bondi Richard Bondi. Subtitled A Programmer's Guide to the Microsoft CryptoAPI which describes what the book is about. http://www.cryptovb.com/books/bondi/bondi.html
Extractions: Bruce Schneier, author of Applied Cryptography and CTO of Counterpane Internet Security, Inc See authors description below. Publisher Author Richard Bondi Pub. Date September 2000 ISBN Format Purchase I wrote this book in order to make strong cryptography available to as many Visual Basic programmers as possible. The best way to do that was to write some very intuitive VB COM wrappers, and release them to the world with an Open Source license. That kind of license both permits and encourages programmers to make the source code available to other programmers, and to modify it for their own use, free of charge. (You can read more about Open Source licenses here Unfortunately, cryptography is complicated. That means that there can be no such thing as simple COM cryptography objects per se. In order to program with cryptography, a programmer must first have a good grasp of the basics of modern cryptography. Therefore my approach was to write a book that does that, and then write my COM objects so that they would be intuitive and simple for someone who understands cryptography. So my book has three main goals: Explain modern cryptography to Visual Basic programmers (Chapter 1).
Honors Seminar In Cryptography Honors Seminar in cryptography. Spring Semester, 2002. University of Illinoisat Chicago. Seminar Outline. Part I. cryptography before 1960. http://raphael.math.uic.edu/~jeremy/crypt/crypt.html
Extractions: Honors Seminar in Cryptography The Honors Seminar in Cryptography is a one-hour-a-week course for members of the Honors College at UIC on the basics of Cryptography, the science of secret communication. Once pursued unscientifically by diplomats, spies, and puzzlers, Cryptography has developed into a highly mathematical science. In this seminar, we will discuss the basic elements of this science. In addition, we will review how the Allied efforts to break German and Japanese codes contributed both to better cryptographic techniques and to other developments in computers and mathematics. We will learn about modern techniques of public key cryptography, and and we will discuss the many important implications that Cryptographic science and policy has for civil liberties, commerce, and law enforcement. While not a technical course in mathematical cryptography, participants in the seminar will need to be willing to learn some basic probability and number theory, and to use computers for some projects. They will also be expected to actively participate in the discussions. This Web Page is still under development! Send comments to

Alt.security.keydist Resources Instructions for distributing public keys on Usenet. Also features information and links of interest to those interested in cryptography rights. http://www.alt-security-keydist.info/
Extractions: This site is a collection of resources about and relating to alt.security.keydist , a newsgroup used to distribute public encryption keys (such as those used by PGP and GPG ) through the UUCP NNTP netnews system. The FAQ was created in 1997. After a few years of inactivity, it's now being posted to the group every 30 days. The FAQ was last updated 1 January 2004. The alt.security.keydist FAQ is a "news.answers-approved" FAQ , and therefore archived at most major FAQ archives on the Internet, including the rtfm.mit.edu FTP server and FAQS.org Since alt.security.keydist is intended for people who use both Usenet and public key encryption, I've decided to add a quick list of software that helps people use public key encryption on Usenet. A list of other cryptography-related newsgroups is also available.

Extractions: Security and privacy have long been important issues forming the basis of numerous democracies around the world. In the digital age, securing personal information and ensuring privacy pose to be issues of paramount concern. At first glance, one might find it gratifying that an online website greets the person by their first name, sends them emails when goods of their taste are added, or recommends goods services based on their demographic profile, previous visits, etc. An astute surfer though will also see the privacy drawbacks in such services. Who else is being provided this information? Is there a way to ensure the security of this information? What happens with the information if the company meets financial diffuculties and has to liquidate its assets? Where does all that "private information" go? Many studies over the last few years have suggested that a majority of consumers are concerned about when, what and how their personal information is being collected, how this information is being used and whether it is being protected. They want to know whether the information is being sold or shared with others, and if so with whom and for what purposes. They also want to have control over their privacy in today's digital age where strides in telecommunicaiton, storage and software technologies have made monitoring a person's activities effortless.
