A while back I happened across this article Buy celebrex without prescription, on programming.reddit.com -- "Moving the 'C' in 'MVC'" -- about web applications whose logic is implemented primarily on the client-side, in javascript, as opposed to the server-side. Celebrex in uk, Interesting stuff, the sort of thing that'd bubbled around my head at one time or another.

That article mentioned clipperz.com and their concept of a "zero knowledge web app." The idea here is to implement client-side cryptography in javascript and store nothing on the serverside except wads of encrypted data, celebrex for order. Celebrex malaysia, Data that is encrypted on the client, that is, celebrex generic. Cheap celebrex no rx, So it never passes over the wire in the clear, and it's never decrypted on the other side of the wire.

That's pretty cool, celebrex online without a prescription. Buy celebrex no prescription required, In fact, clipperz.com hosts their own best shot at a zero-knowledge web app, cheap celebrex overnight delivery, Celebrex cheap, a password manager. A web-based password manager seems insanely insecure, but not so if you implement it as a zero-knowledge web app, buy celebrex without prescription. It's basically like keeping a local HTML with all your passwords and javascript which allows you to click on those passwords and have it launch the appropriate page and log in to the service in question (Google, buy celebrex, Real celebrex without prescription, Facebook, whatever) -- except that instead of keeping it locally you're keeping an encrypted version of it on clipperz.com's servers.

As far as usage goes, find celebrex without prescription, Cheapest celebrex price, it's pretty simple, but unusual, celebrex order. Find cheap celebrex, In a normal web app, you log in once, celebrex online sales, Celebrex pills, after which you are recognized by cookies until some timeout period. That's because you're logging in to an app running on the server, drug celebrex, Celebrex in us, and cookies help maintain the illusion of a persistent connection. In clipperz, celebrex online without prescription, Buy cheapest celebrex on line, the app is running in your browser. Buy celebrex without prescription, So if you close the page and come back to it, you have to log in again. But you can leave that page open forever and it never times out, order celebrex on internet, Celebrex purchase, because there's a real connection between you and the app (an open browser window) so there's no need for the whole cookie deal.

Adding logins to the app is an unusual process but easy once you get used to it. When you're on the login page to the service in question (myspace, cheap celebrex tablets, Buy celebrex low price, yahoo, whatever) with your username and password typed in the blanks, cheap celebrex, Order cheap celebrex, you can click on a bookmarklet you've previously saved from clipperz, and it will extract a chunk of JSON data from the page you're on, celebrex cheap drug, Find cheap celebrex online, representing the login form, your username, celebrex for sale, Celebrex alternative, and password. You cut and paste that into your running clipperz session in another tab or window, celebrex from canada, Low price celebrex, and it takes that JSON chunk and adds that to its data store, and now you have a clickable link on your clipperz page which will log you in to that service.

Knowing I've got an instant one-click login to a service makes it easier for me to make a habit of logging out of a service when I'm not using it.

It's also easy to maintain more than one login to the same service using clipperz, cheap celebrex on internet. Tablet celebrex, Each is just one click away.

Clipperz has a sometimes-friendly, sometimes not-so-friendly competitor named "PassPack, buy celebrex internet, Celebrex free sample, " whose authors consider Clipperz.com's zero-knowledge thing "fallacious" in some way, though reading through it I'm still not sure exactly what they think is wrong with Clipperz's way of doing things, buy celebrex online cheap. I guess the idea is that any privacy and security that Clipperz provides for you that PassPack doesn't is just silly and you shouldn't worry your pretty little head about it, for such worrying is a "fallacy." I don't know, buy celebrex without prescription. Celebrex overnight shipping, It sounds like PassPack might be easier to use, and harder to understand what they're doing, celebrex side effects. With clipperz you just have a username and passphrase; with PassPack you have a username and password and an additional crypto key. (UPDATE: see comments below, from Tara from PassPack for clarification of what they were getting at.)

In any case, PassPack and Clipperz have each posted a list of the pros and cons with their respective services. Overall I have to say that having actually used Clipperz for a while I don't see anything about PassPack that encourages me to explore it as an alternative.

Anyway, my review of Clipperz after a couple weeks of use -- thumbs up. It's unusual but worth getting to know.
