Generally yes, but Hushmail offered two methods of encrypting emails: on their servers and in a Java applet that did it locally. What came out during the earlier revelations was the company handed over email that they decrypted on their servers, but couldn't do so for the applet based encryption. They said up front that the applet was far more secure.

Encryption + web-based don't mix well (Score:5, Insightful)
Anytime your private encryption key is "over there" you are at risk. If your private key is stored on *their* servers in such a manner that *they* can get to it, your privacy is at risk.
As a software developer, I'm in a pilot program to use encryption for digital signatures. Despite the relative simplicity of using openSSL functionality, it's been surprisingly painstaking and laborious to put everything together.
See, real security requires outright paranoia. How do you prevent your CA key from being compromised, in such a way that you can all-but guarantee that it hasn't been? To do this, you have to make it not only unlikely, but impossible to be compromised in every conceivable way. How do you prevent your client's private key from being compromised, in such a way that you can all but guarantee it? How do you prevent a malicious client from obtaining a signed certificate? How do you prevent 3rd parties from MITM attacks? How do you provide high-level security for all the above, while still providing redundancy for disaster recovery? How do you prevent compromises stemming from a social engineering attack?
Not including implementation and ongoing maintenance of these procedures, the cost of just proving that you have all these measures in place runs to many thousands of dollars!
A solution that answers all these and every conceivable related question is surprisingly difficult, and many, if not most, of the problems are not technical, but social.

From my own admittedly anecdotal experience, I'd say Hushmail is just a way to make money. Not only do they constantly bombard you with pleas to upgrade to their paid service, but they are supposed to delete your account if you don't check it every 3 weeks. But my account was deleted under this claim when it had been only 1 week since I checked it. Yes, I'm sure. Not only that, but when I tried to create an account with the same name, whenever I pressed okay I got an error message that I couldn't use that name without upgrading. After that I'd started using GPG with Gmail. Both are free.

It's also NOT necessarily true that for every brilliant person in the government, there's another who works elsewhere, at least specifically on cryptography. In particular, the NSA is one the largest employers of mathematicians on earth. Most other employers who hire mathematicians have other jobs for them to do, so most of their time is occupied with other problems. By contrast, the NSA can (apparently) afford to hire quite a few who are allowed to concentrate entirely on cryptology.
Given the secrecy of the NSA in general, it's essentially impossible to come up with numbers that are either exact or concrete, but it certainly seems possible and reasonable that government agencies (in general) could have considerably more time and effort to devote to this subject than the entire rest of the world.
My feeling, however, is that the gap has been narrowing for quite a while now. From the design of DES, it appears that the NSA was aware of differential cryptanalysis (but not linear cryptanalysis) at that time; it became publicly known quite a bit later. As for AES, however, the rest of the world has caught up to the point that AES can be used on DOD Secret data, and the variants with 192- and 256-bit keys are cartified for DOD Top Secret data.

Strong encryption was a commercial necessity, so the attempts to control the industry had to be dropped. The export restrictions disappeared, and because DES was now too weak to be useful, the new AES standard was introduced.

Encryption is well understood and researched by academics working in public. Sure, governments have their own secret research, but a lot of very clever people all around the world have been testing AES and Twofish for weaknesses for years and so far have found none. Governments don't have any magical ability to find flaws in encryption that ordinary academics don't.
Having said that, perhaps if you are Osama Bin Laden you might want to be a little bit paranoid. In theory, with a few billion dollars you could build a machine capable of cracking AES in months. So far there is no evidence such a machine exists, but... Most people don't have to worry about that though, even if they are doing something that could get them in serious trouble - certainly the national police, Interpol or even secret services (MI6/CIA) don't have any chance of breaking AES by brute force. Of course they could torture you now but even that isn't much of a threat to anyone not labelled a terrorist by the US.

By the same principle, don't fuck around, don't trespass, don't steal, and don't be a crook. Learn the law VERY carefully, keep a copy of Black's Law Dictionary (I think 6th edition is out now) in several different versions. Look up innocent looking terms and verbs in forms. DO NOT consent to anything period. Sign nothing. Be sure you know what is "your name" and what is what someone may call you. Practice your rights. Yes... all of them. A right practiced doesn't need to be infringed, because you already don't have it.
Be very suspicious not of your neighbors but of men in "special" uniforms or funny hats that supposedly give them power over you. Don't let strangers into the house.

Several languages and a good grasp of self defense, tactics and strategy are also quite important. Those with kids who choose to be politically active are extra vulnerable, since kids are the ultimate Achilles Heel.
Never ever trust strangers. Trust people in uniforms even less. Never ever get into a stranger's car, despite what you see in the movies. If they want to talk to you, they can get into yours. If you are confronted by a "friend from high school" and like most average people you can't remember who you met yesterday, nevermind back then, look behind you, you're probably about to get cattle prodded in the back and shoved into a van.
These were simple coping strategies for those who were not average plebeians and who survived the cullings of communism. I lost relatives who were educated, men I could've learned much from. I never met them because they were taught that self defense was for cops and soldiers. And when the king's men were gone, and the cops were coopted to communism... there was nobody to protect the smart, educated, "civilized" (i.e. willingly helpless) men from the cleansings. The ones who weren't "lifted" and sent off to Siberia, were enrolled into a front line regiment and given crap gear and no real training. Very few returned, most scarred for life. All I saw of them while growing up were pictures over mantelpieces. Grandmothers mourning long lost brothers or maimed cousins. That is the fate of the helpless of those who depend on others for their protection...

Standard symmetric and asymmetric ciphers are more or less immune to these problems (#1: swapping passwords securely is a lot easier than swapping large amounts of binary data securely; #2: you can keep the password in your head instead of stuffing a keychain drive under your mattress; #3: no such issue).

You insert the rod under the end of the envelope flap, where there's no seal. You catch the letter where it's folded, with one side of the fold on each side of the split, then twist the rod to roll the letter up, and remove it back out the end. When you're finished reading it, you reverse the process to re-insert the letter into the envelope.
