An Overview of Cryptography 1. INTRODUCTION Does increased security provide comfort to paranoid people? Or does security provide some very basic protections that we are naive to believe that we don't need? During this time when the Internet provides essential communication between tens of millions of people and is being increasingly used as a tool for commerce, security becomes a tremendously important issue to deal with. There are many aspects to security and many applications, ranging from secure commerce and payments to private communications and protecting passwords.

Reverse MD5 hash lookup This form uses several MD5 databases to look up an MD5 hash and return its original counterpart. You may use the second field to first generate an MD5 hash of a string to use in a reverse lookup. The results of the reversed hash will be displayed here.

Handbook of Applied Cryptography Alfred J. Menezes, CRC Press ISBN: 0-8493-8523-7 October 1996, 816 pages Fifth Printing (August 2001) The Handbook was reprinted (5th printing) in August 2001. The publisher made all the various minor changes and updates we submitted. Gmbh The Pound program is a reverse proxy, load balancer and HTTPS front-end for Web server(s). Pound was developed to enable distributing the load among several Web-servers and to allow for a convenient SSL wrapper for those Web servers that do not offer it natively. Pound is distributed under the GPL - no warranty, it's free to use, copy and give away. Pound is a very small program, easily audited for security problems. It can run as setuid/setgid and/or in a chroot jail. Pound does not access the hard-disk at all (except for reading the certificate file on start, if required) and should thus pose no security threat to any machine.
10 Search Engines to Explore the Invisible Web The Invisible Web refers to the part of the WWW that’s not indexed by the search engines. Most of us think that that search powerhouses like Google and Bing are like the Great Oracle”¦they see everything. Unfortunately, they can’t because they aren’t divine at all; they are just web spiders who index pages by following one hyperlink after the other. But there are some places where a spider cannot enter. Take library databases which need a password for access.
Visual Cryptography What is Visual Cryptography Visual Cryptography is a special encryption technique to hide information in images in such a way that it can be decrypted by the human vision if the correct key image is used. The technique was proposed by Naor and Shamir in 1994. Visual Cryptography uses two transparent images. One image contains random pixels and the other image contains the secret information.

How to Make Anything Signify Anything Detail from a photograph of World War I cryptographers trained by William and Elizebeth Friedman, Aurora, Illinois, early 1918. By facing either forward or sideways, the soldiers formed a coded phrase utilizing Francis Bacon’s biliteral cipher. The intended message was the Baconian motto “Knowledge is power,” but there were insufficient people to complete the r (and the w was compromised by one soldier looking the wrong way).Included as a pull-out poster in issue 40, Knowledge Is Powe is also available for purchase in an unfolded version suitable for framing.
PuTTY Download Page Home | Licence | FAQ | Docs | Download | Keys | LinksMirrors | Updates | Feedback | Changes | Wishlist | Team Here are the PuTTY files themselves: PuTTY (the Telnet and SSH client itself) PSCP (an SCP client, i.e. command-line secure file copy) PSFTP (an SFTP client, i.e. general file transfer sessions much like FTP) PuTTYtel (a Telnet-only client) Plink (a command-line interface to the PuTTY back ends) Pageant (an SSH authentication agent for PuTTY, PSCP, PSFTP, and Plink) PuTTYgen (an RSA and DSA key generation utility). LEGAL WARNING: Use of PuTTY, PSCP, PSFTP and Plink is illegal in countries where encryption is outlawed. I believe it is legal to use PuTTY, PSCP, PSFTP and Plink in England and Wales and in many other countries, but I am not a lawyer and so if in doubt you should seek legal advice before downloading it. You may find this site useful (it's a survey of cryptography laws in many countries) but I can't vouch for its correctness.
99 of the best Windows freeware programs you may not know of Because of the popularity of my previous article on Help Desk Geek entitled 99 ways to make your computer blazingly fast, I’ve decided to write another list post with 99 items, but this time on Windows freeware programs that you may have not heard of. If you search for “best freeware programs” or “top freeware apps”, you’ll get lots of lists, but mostly with programs everyone has already heard of: AVG anti-virus, 7-zip, Firefox, OpenOffice, etc, etc. That’s all nice and fine, but what about all those little gems programs that work great, but don’t get all the headlines? In this article, I will try my best to mention as many small name freeware programs as I can that can help make you more productive! As usual, I write for both Help Desk Geek and for Online Tech Tips, so I will be linking to old posts throughout if I’ve written about it or else I will link out to the main website for the program. These are written in no particular order!
