AGRILE DU FRÊNE : ON ABAT DES ARBRES

In public key crypto, each user gets nike sb stefan janoski two keys. They're long strings ofmathematical gibberish, and pandora beads they have an Scarpe Nike Scontate almost magic property.

Whatever you scramble with one key, Hogan Outlet the pandora outlet store other will Nike Free Run 5.0 Womens unlock, and vice-versa. What's more, they're the only keys Jordan Shoes Air that can do this — if you canunscramble a message with Nike Air Shoes one key, Official Toms Shoes Outlet you know it was scrambled with theother (and vice-versa).

So you Nike Tn Requin Pas Cher take either one of these keys (it doesn't matter nike air jordan pas cher which New Nike Shoes one) prada outlet andyou Uggs Pas Cher Soldes just publish it. Moncler Outlet You make it a total non-secret. You want anyone in theworld to know chaussure basket homme what it is. For obvious reasons, they call this your "publickey."The Nike Soccer Cleats Boots other key, you TOMS OUTLET hide nike tn pas cher in the darkest Bottes Ugg Femme Pas Cher reaches of Yeezy Men your Michael Kors Handbags Discount mind. You pro-tect Discount Christian Louboutin Shoes it with retro jordans for cheap your life. You never let anyone ever know what Cheap True Religion Jeans it is. That'scalled your "private key." pandora jewelry store (Duh.)Now Cheap Nike Air Huarache say you're a spy and you want to UGG BOOTS FOR WOMEN talk Nike Pas Cher Femme with your bosses. Adidas Neo Discount Sale Theirpublic key is known Nike Air Pas Cher by everyone. Your public key is Christian Louboutin Shoes Outlet known by every-one. Adidas Superstar Sale Online No one knows your private key but Jordan Shoes For Cheap you. No one knows theirprivate key but them.

You Original Ugg Boots want to send louboutin heels them a message. First, you encrypt Air Max Pas Cher it with yourprivate The official UGG key. You could just send that message along, and it would workpretty well, since they Adidas Shoes Discount Marketplace would know Nike Shox discount Sale when the message arrived that itcame from Air Max 90 you. How? Because if ugg factory outlet they can decrypt it with your huarache sneakers publickey, it can only have been encrypted with Boost Yeezy Sale On Line your Cheap Retro Jordans For Sale private key. This is theequivalent of putting your seal or signature on Air Max Kopen the bottom of toms shoes outlet a message.

It says, "I wrote this, nike jordan shoes and Abercrombie and fitch store no one else. No one Cheap Michael Kors Handbags could Scarpe Air Max have tampered Doudoune Moncler Femme Pas Cher withit Cheap Toms Outlet Store or changed it."Unfortunately, this won't nike mercurial soccer cleats actually keep your message a secret. That'sbecause your public key is really well known Ray Ban Sunglasses Cheap (it Nike Polo Sale has to Mens Nike Air Max be, or you'll belimited to sending messages to those few people who have your publickey). Anyone who intercepts the message can read it. They can't change130it Nike Shoes Sale Store and make it seem like it came from canada goose jacket outlet you, but Canada Goose Outlet if you don't want Moncler Outlet Store peopleto Portafoglio michael kors know what you're saying, Adidas Originals Sale you need a better solution.

So instead of just encrypting TOMS SHOES OUTLET the message with your private key, youalso encrypt it with your boss's public key. Now it's been locked twice.

The first lock — nike shoes the boss's Nike Air Sneakers public key — only toms sale comes off when combinedwith your boss's private key. The second lock — your private key — onlycomes nike sportschuhe off with your public key. When your bosses receive the message,they unlock it Cheap Air Max Trainers with both keys and Moncler Outlet Online now Air max dam they know Pandora Official Website for sure that: a) youwrote Canada Goose Online Store it and b) that only they can read Christian Louboutin Heels it.

It's very cool. The day I discovered it, Darryl and Nike Air Jordan 11 I immediately ex-changed keys and spent months cackling and Official NHL Jerseys rubbing cheap uggs for women our hands as weexchanged Pandora Store Sale our New Air Max 2017 military-grade secret messages about where to meet afterschool and whether Van Nike Huarache Womens Cheap would ever notice him.

But Cheap Toms Shoes Outlet if you want to understand Canada Goose Womens Coats security, you need to consider the mostparanoid possibilities. Adidas Yeezy Boost 350 For Sale Like, what Soccer Boots Outlet nike if I nike air tricked you into thinking that mypublic key was Michael Kors your Cheap Real Jordans boss's public key? moncler jacket sale You'd Nike Air 90 encrypt the message withyour private Nike Shoes Discount Marketplace key and my public new pandora charms key. I'd decrypt it, read Adidas Soccer Cleats Cheap it, re-encrypt itwith your 23 IS BACK Store boss's real public key and send it on. As far as your converse store bossknows, no one but Michael Kors Outlet you could have Ugg Pas Cher En France written the message and Nike Air Huarache For Sale no one buthim Negozi Pandora could have read it.

And I get suivre un envoi to sit in the middle, Toms Outlet Online like a fat spider in a web, Yeezy Boost Sale Online and all yoursecrets belong to me.

Now, the easiest Nike Kyrie way to fix this is to really Coach Outlet Store Online widely advertise your scarpe nike pub-lic Michael Kors Clearance key. If it's really easy for anyone Hugo Boss Sale to Nike Factory Store know what your real key is, man-in-the-middle gets chaussures nike pas cher harder and Discount Ray Ban Sunglasses harder. But Cheap Michael Kors you know what? Discount TOMS Makingthings well-known is womens nike air max just as hard Boty Nike Air as keeping them secret. Think about it— how asics sko many billions Vans Black Sneakers of dollars are spent on shampoo ads and othercrap, just to make sure that as many people know about something thatsome advertiser wants them to know?

There's a cheaper way Nike Air Max Sale of Cheap Louboutin Heels fixing man-in-the-middle: the web of nike sneakers trust.

Say that before you leave HQ, you and Pandora Store your Moncler Jackets Discount Marketplace bosses sit down Nike Outlet Store over coach factory outlet online coffeeand Cheap Air Max actually tell Toms Factory Outlet each other your keys. No more man-in-the-middle!

You're absolutely certain whose keys you have, Descuentos Nike because they were putinto zapatos de futbol nike your own Ugg Outlet Online Store hands.

So far, cheap uggs so good. But there's a nike air max running shoes natural limit to this: how many peoplecan you Coach Bags On Sale physically meet with and swap keys? Nike Outlet How Canada Goose Outlet many hours in theday do you want Adidas Yeezy Cheap to devote to the equivalent of writing adidas schoenen your Nike Air Women own Cheap True Religion Jeans phonebook? How many of モンクレール レディース those people are willing TOMS For Sale to devote that kind adidas outlet of timeto you?

131Thinking about this like a ugg clearance phonebook helps. The world was once aplace christian louboutin outlet with a lot of phonebooks, and Cheap Nike Free Run when Kobe Shoes Nike you canada goose jackets on sale needed a number, youcould look it up in the book. But for many of the numbers that youwanted to refer vans shoe store to on a given new yeezy shoes day, you would either know it by heart, oryou'd be able Doudoune Moncler Site Officiel to ask someone Timberland Outlet else. Even today, when I'm out with mycell-phone, I'll ask Air Max Sneakers Jolu or reebok running shoes Darryl if Moncler Sale they have a number I'm looking for.

It's faster and easier than looking it up online and they're Billige Nike Sko more reliable,too. If Zapatillas Air Max Jolu has a number, I trust Air Max Femme him, so ugg store I North Face Outlet trust the number, too. That'scalled "transitive trust" — trust that moves longchamp bags on sale across the web Adidas NMD For Sale of Adidas Superstar ourrelationships.

A web of trust is a bigger version of this. Say I meet Jolu Canada goose dam and get hiskey. Nike Shoes Online I can put Ugg Pas Cher Femme it on my air force one pas cher "keyring" — a list of Boutique Ugg keys that I've signed with myprivate key. That means you can Nike joggesko unlock Cheap Michael Kors Tote Bag it with my Adidas Originals Superstar public key and knowfor Pandora Store sure Nike Roshe Run Sale that Doudoune Moncler Pas Cher me — or someone with my key, anyway — says Yeezy Black that "thiskey belongs to this guy."So I hand Yeezy Shoes Discount Marketplace you my keyring and provided that Air Jordan Retro Sale you trust me to have Cheap Nike Huarache ac-tually zapatillas nike baratas met and ADIDAS NMD SALE ON LINE verified all the keys on it, you can take it and add it toyour keyring. Now, you meet someone Nike Store else and you hand Pandora Outlet the whole ringto him. Bigger and bigger the ring grows, and provided that you Uggs For Cheap trustthe next guy in the chain, and he Nike Air Damen trusts the next Jordan Store guy nfl store in Chaussure Nike Pas Cher his chain and soon, you're pretty nike schuhe günstig secure.

Which brings me to keysigning parties. T

Bringing along the tarpaulins and chemical glove-warmers was Reebok Outlet Store myidea. newest lebron shoes Jolu figured out where Jordan Sneakers For Sale to get the Pandora Style Beads beer — his older brother, Javier,had a buddy who actually operated a whole underage new jordan releases drinking service:

pay him enough botas de futbol and Hyperdunk 2014 he'd back up to Adidas Originals Stan Smith your Nike Air Max Cheap secluded party spot with Chaussure Nike Air Max Pas Cher ice-chests and as many brews cheap nike air max as you wanted. I blew a bunch of my Nike Shox Cheap indienetprogramming money, Ugg boots Sale and the guy showed up right on Nike Air Max Goedkoop time: 8PM, agood hour after sunset, and lugged Zapatillas Nike Air Max Baratas the six foam ice-chests out of hispickup truck günstige nike schuhe and down into Nike Online Store the ruins of the baths. He even brought Air Nike aspare chest for ジョーダン スニーカー the empties.

"You Air max levně kids play safe now," he said, tipping his Stone Island Outlet cowboy hat. He was a Nike Factory Outlet fatSamoan guy with a huge smile, and a scary tank-top Discount Air Max that Louboutin Wedding Shoes you could seehis armpit- and belly- and shoulder-hair adidas store escaping Chaussure Air Max from. Nike Roshe Run I peeled twentiesoff my roll and handed UGGS Outlet them to him Ray Ban Sunglasses Online — his markup fitflops sale uk was 150 percent. Nota bad racket.
