Who are our masters of surveillance today? Most are located at the National Security Agency, the giant “Crypto City” complex located off Interstate 95 between Washington and Baltimore. The agency vacuums up 650 million intercepts a day — called signals intelligence, or sigint — from satellites, ground stations, aircraft, ships and submarines around the world.

The NSA conducts broad-based surveillance indiscriminately over communications lines that few bad guys even use any longer. “Big Noddy,” as those in the know call the NSA’s vast “Ear in the Sky,” has capabilities that dwarf the Bletchley Park World War II enterprise, but it isn’t picking up much because the smartest terrorist groups have long since stopped talking about their plans over cell phones or land lines — or to the extent they do, it’s probably to plant disinformation. Today the challenge isn’t decoding an intercepted message from a known enemy; instead it’s figuring out what is and isn’t a message and who the enemy is.

Hidden behind tall earthen berms and thick forest trees halfway between Washington and Baltimore is a dark and mysterious place, virtually unknown to the outside world. Nicknamed Crypto City, it is protected from outsiders by a labyrinth of barbed wire fences, massive boulders placed close together, motion detectors, hydraulic anti-truck devices, and thick cement barriers. Should a threat be detected, commandos dressed in black paramilitary uniforms, wearing special headgear and brandishing an assortment of weapons including Colt 9mm submachine guns stand guard. They are known as the “Men-in-Black.” Telephoto surveillance cameras peer down, armed police patrol the boundaries, and bright yellow signs warn against taking any photographs or making so much as a note or a simple sketch, under the penalties of the Internal Security Act. What lies beyond is a city unlike any other place on earth, one that contains what is probably the largest body of secrets ever created. It is the home of America’s ultrasecret National Security Agency, responsible for eavesdropping on the world and breaking virtually impossible foreign code and cipher systems.

Made up of more than sixty office buildings, warehouses, factories, laboratories, and living quarters, it is a place where tens of thousands of people work in absolute secrecy. Most will live and die never having told their spouses exactly what they do. The secret community is also home to the largest collection of hyper-powerful computers, advanced mathematicians and skilled language experts on the planet. Within the city, time is measured in femtoseconds—one million billionth of a second, and scientists work in secret to develop computers capable of performing more than one septillion (1,000,000,000,000,000,000,000,000) operations every second.

The below article was something I wrote over a year ago for this site and a topic very much relative to todays world. Enjoy the article and I’m happy to hear any comments you may have regarding it.

Organization: International Alliance Privacy Services

This may become quite a large article, but it will cover many topics I have been meaning to write about for quite some time now. This article will focus on discerning the truth from lies, fact from fiction. Sit back and enjoy the article.

Looking around the internet, I see many websites in the “privacy” business making claims that are just flat out impossible to be true. I have seen claims of such high encryption levels, ultimate protection that not even Satan himself could penetrate. Yet as I see where the claims are coming from, most of them are United States based claims. As all who are internet wise, we know that the United States is pro-censorship and that the omni-present National Security Agency is ever present in as many places as possible. Many years ago the NSA had 17 acres of under-ground super computers to monitor national and international communications. Do you know how many super computers make up 17 acres of land? There must not be much soil left under Fort Meade, Maryland where the home of the NSA resides. Now what do you think they are doing nowadays with quadruple the amount of resources and black-ops funding? Lets also add non-congressional oversight.

Some of you might remember the press news articles and media attention received over U.S. President George Bush’s policy of illegal wire tapping. However, most of you didn’t hear that AT&T was one of the biggest data pushers of its clients data right into the hands of the NSA. (source # 1) (Mark Klein – Former AT&T Technician) (source # 2) Although this situation was brought to national and international attention, do you think it really stopped anything? Yes, all you SBC internet users who are now AT&T clients can rest assured that you have absolutely no internet privacy either now or in the future. But do you think it really ends there? Nope.

Now we are not only going to focus on insecurity in the United States. There are more countries than you might think engaged in this practice. We will hit on those countries soon enough. The next biggest lie we came across was the boasting of a 100% up time. Now looking at this situation a bit closer, we see how and why they can make such a claim: if you have 7 servers and 3 are down and 4 are up, then you can claim a 100% up time. Thats the basic philosophy of many in the privacy business. Now how is this an accurate or a fair assessment of their ability to keep their servers up? Its not and its an out right lie. A further analysis of these same providers is that most, if not all, of their servers are located in only one country such as the United States where privacy is non-existant and they, or their data centers can be made/forced to give up their client data or have their servers physically confiscated at any time. Our data also shows that many of these organizations do not have actual hard drive encryption on their servers which means if the law does come and take them, guess what? Your activities are going to be laid out on a silver platter for the NSA/FBI/DIA/DEA/ICE/NRA/IRS/CIA or any of the other 3 letter agencies (TLA) I may not thinking about at the moment.

But its not encryption alone that can save your hide. It is a well known fact that the NSA only makes contributions to the cryptographic world when they can crack the encryption before its released to the unsuspecting public. (source # 3) It is also a known fact that Microsoft and the NSA have collaborated and Microsoft has implanted NSA decryption keys in all its versions of the Microsoft Windows operating systems. (source # 4) (source # 5)With this knowledge in mind, how does the U.S. Government claim democracy when they have trap doors built into all Microsoft operating systems, most of the popular firewalls in use today, and they can crack your encryption keys with pretty much ease? (source # 6) This leaves the never answered question: why does the U.S. Government reserve the right to walk into the back doors of any computer it wishes world-wide? Who made them the gate keeper?

This brings me back on point here: for those of you on U.S. based “privacy servers” who are under the impression that you are completely safe and untouchable, think again. You can, and probably are, monitored all the time by the flow of data re-routed to the NSA or its affiliates. Simply put, U.S. networks are simply not safe. Bearing this in mind, you do not have to be a criminal to want your privacy while you are online. You may be a priest that likes a little porn now and then and want that secret kept a secret. Why should any government be allowed to take that privacy from you? Its my opinion that this is something that should not be allowed. Another example is if you are in a highly competitive and volatile business and have the edge on your product/service and the U.S. Government thinks they have the right to know whats on your computer even though you have not broken any laws. Again, how can you call yourselves a democratic government if your # 1 goal is to spy on every possible person you can?

Ok, getting back on topic here: another tactic used by so-called privacy organizations is through the use of “free” software. How do you know that the software they have you use is not already tainted before you get it? What if it contains a back door scripted in by either the software maker, or in cooperation with the government? If its proprietary software, you don’t know. So how do you really know what the software is actually doing? 99.9999% of all people that download ip changing programs have absolutely no clue how these programs work and where security vulnerabilities exist. Many of the “one click solution” people are happy if it just works. They don’t care how it works, as long as it does and as long as it’s not too complicated for them. So with this theory in mind, why bother? If you want to conceal your online identity, don’t you want to at least know how a program works or what you are installing on your computer? Surprisingly, most people don’t care which is just a sad example of how the world works.

The software utilized by us, International Alliance Privacy Services, is simply one program. This is an open source program released to the general public which is provided absolutely free of charge. It was not written or produced by any of our staff. Open source software is maintained by the general public that participates in the development of a project or design of a program. Open source means that the program is not proprietary and can be easily taken apart and looked at for whats under the hood and exactly how it works. This is the destiny we believe in and the methods we use to really protect your privacy are top notch. We despise the use of exploitable software based on java, which is why we simply will not use it. We believe in gaining the general public’s trust by showing you exactly how we secure your privacy. We write technical/security articles for your understanding and benefit. We owe our success to you, the reader, so why not further educate you all in the same process? Even if you choose not to use our services, at least you will be armed with the right knowledge and will know what to look for when choosing the right privacy organization to meet your needs.

Another unacceptable practice we have seen from other privacy organizations is that their servers are all marked with easily identifiable host names. Now if you are using the services of a privacy organization with servers that are shouting “I’m a proxy server and I belong to so & so” how is this protecting you? Any one who looks at the host name is automatically going to consider blocking/banning you right from the get go. International Alliance Privacy Services does not believe in this practice. All of our servers are only identifiable as code names and do not declare they are part of our networks or part of our family of domain names. We give all of our servers general names that do not call attention to themselves. We believe that if you choose to use our services, why would we put you on a server that screams “proxy!” and leads right back to us? Thats not how we operate.

One of the final topics that seem to lure potential clients in is through the usage of exotic places to have servers in. Just because a privacy organization may have servers in exotic locations or a few islands, how do you know if they are safe? Did you stop to think about the treaties those countries might have with other countries? What about data retention laws as specified by the governments of those exotic places? One particular place frequently mentioned among privacy organizations is the country of Panama. What these organizations fail to mention in their sales pitch is that Panama has treaties with the United States for sharing information. Basically put, hosting a server in Panama is no different than hosting it in the United States. Safe? Not likely.

In conclusion, we hope that you have learned something. If not much, at least something that you can use to help you make a better informed decision now or in the near future. We are always open to your questions or comments and critique of any documents/articles written by International Alliance Privacy Services. If you have questions, please ask instead of assuming! Its better to know and receive, then not to ask and just assume. When making the decision to use a privacy organization, I hope this small article helps you out. Thank you.

Folks, I wanted to hit on this topic again as it is very critical in these days and times. You do not have to carrying state secrets, be a criminal, or any other devious act to want private communications within your email account. You also don’t have to be a technical expert either. This blog post is intended to be a step by guide in setting up a FREE encrypted email account.

I always recommend purchasing your own domain name. I say this because its always preferred to run your own email services on a private server rather than using the services provided by Hotmail, Yahoo, or Gmail. For those of us in the technical security field, we know who’s in bed with the U.S. Government and who’s not. Let’s look at Gmail, provided by the good folks at Google. Who runs Google’s technical department? None other than ex-NSA (U.S. Government National Security Agency) Matt Cutts. Now why would an ex-NSA agent quit the National Security Agency to run the technical side of things for Google? Its the world’s largest database and guess what? Uncle Sam wants constant access to it! With their own man running the show, they have it. Even though he claims he got out, we all know there’s no official out for agents. Once Uncle Sam owns you, he always owns you.

There’s not much to say in regards to the Microsoft Hotmail brand. Again, this is another U.S. corporation well documented as being in bed with the U.S. Government. Yahoo doesn’t have a clean past either. The makers of Hushmail surely have just as bad a record as well, currently only offering 2048 bit encryption keys at best that reside on their own servers so that they can capture your passphrase when decrypting your emails which will then allow them instant access to all past and future emails that are encrypted with your key.

This step by step guide will show you how to use encrypted email that doesn’t require a key to remain on any server, uses the strongest encryption known to man (currently 4096-bit RSA), and uses a completely open-source application infrastructure. It is currently not known if the NSA can yet crack a 4096-bit key, but it is highly unlikely. Even the best super computers would have quite a difficult time at it. Some estimate it would take nearly 200 years to crack a 4096-bit encryption key while others think it may only be 20-30 years away. Either way, this is excellent news for the common folk that wish to have truly private email correspondences.

Ok, now on to the guide. You will need to obtain the following tools before we get started. These tools are based on the most common operating systems currently in use: Microsoft Windows XP and Vista (all versions). All these things are completely free of charge.

Mozilla Thunderbird
GTK+
Mozilla Enigmail
GNU Privacy Guard

The first thing we want to do after obtaining the above pieces of software is to install them one at a time. Start with GTK+ and GNU Privacy Guard. Once these are installed, move on to the Thunderbird installation and then finally the Enigmail add-on for Thunderbird.

Before we go any further its best to reboot your computer. This way all the pieces of the puzzle have a proper chance of being formally initialized. Once that’s done, we can proceed with the rest of the setup.

As I recommended above, it’s better to own your own domain name and operate your email services from your own server rather than a public one where you don’t know who has administrative access to it. While I understand that that is not always the ideal situation for every one, I’ll dab a little into what we can do with Gmail to make it compatible.

If you cannot obtain your own domain and a private server that hosts that domain, then you need to use a free email service that is POP3 (Post Office Protocol version 3) compatible. Gmail is just such a service. Yahoo wants you to pay for it so they will not be included in this article. At this time I’m not sure if Hotmail offers free POP3 services or not.

Once you’ve rebooted, open up the Thunderbird application. Add your POP3 compatible email accounts into Thunderbird. Once all your account(s) are loaded in there and you’ve properly tested them to make sure they are working, then we can proceed to the next step. You will see a tab for OpenPGP in the upper left hand tab. Click on that. Now scroll down to “Key Management” and click on that as well. A mini screen will appear. Click on “Generate” and then “New Key Pair.” Now a third box appears with a lot of options.

With this third box, we select one of our email addresses that we wish to generate an encryption key for. Once that’s selected, we assigned a passphrase for this encryption key. (This passphrase is like a password and will be needed to decrypt all future emails that are encrypted to your private key.) I wholly recommend a 10-15 character alpha-numeric passphrase. Anything less than that can be considered insecure. Do not use dictionary words, pet names, birthdays, pin numbers, your address or street name. Use something very unique. I highly recommend a 20 character alpha-numeric passphrase.

Now we choose when the key will expire. The default is 5 years. I’ve personally set mine to never expire and recommend all of you to do the same. Now we can click on the Advanced Tab. You’ll see “Key Size.” There are several options here and I highly recommend setting a 4096-bit key size. Directly below that is “Key Type.” There are 2 choices in this section. RSA and DSA El Gamal and I recommend going with the RSA key.

Now we click on the “Generate” button. It will take your computer some time to generate a random key based on your computers ability. Some computers are quick to do it and others take a few minutes and this is primarily based on your computers processing power. Once the key generation is complete, it will ask you if you want to back up these new keys so you can create revocation certificates if you ever lose control of your private keys. I highly suggest you take this option. Save the revocation certificates any where but your main hard drive. A pen drive, usb thumb drive, or an external hard drive are ideal places to keep these.

Once your revocation certificates are safely tucked away in an external location, we need to go back to the main screen of Thunderbird. On the left hand side of the screen you’ll see a pane for your email accounts. Click on the name of one of the email accounts. You’ll be taken to another screen where there are several options. Click on “View Settings For This Account.” A new mini screen will pop up. You’ll see an option for “OpenPGP Security.” Click on that.

Make sure the box is ticked for: Enable OpenPGP Support (Enigmail) For This Identity.” Directly below that, make sure the circle is tick for: “Use Specific OpenPGP Key ID.” Your specific encryption key should automatically be in the box already. Directly below that you’ll see 4 options. Make sure the first 2 boxes are always checked. This is just the signature part and is an integral part of letting others know that you have encryption ability. Since not every one uses encryption, don’t check the other boxes just yet.

Remember, you must exchange public keys with anyone that you plan on sending and receiving encrypted emails to and from. You cannot decrypt email in a normal free email account and this email must reside on a POP3 compatible email service. Using this particular method, emails can only be decrypted and encrypted from within Thunderbird. There is no server interaction here in the actual encryption or decryption as that resides on your individual computer only. This is the most absolute secure way to use encryption.

I will write another article later this week regarding the transport of your email and how TLSv1 (Transport Layer Security version1) can provide much better security than the traditional SSLv3 (Secure Socket Layer version 3) could ever do and how we can integrate SSHv2 (Secure Shell version 2) to help us achieve this effect. (SSHv2, besides providing transport security under an immense amount of encryption can also be used to completely hide the origin of where the email actually originated.)
