Yahoo To Add PGP Encryption For Email
Bismillah (993337) writes Yahoo is working on an easy to use PGP interface for webmail, the company's chief information security officer Alex Stamos said at Black Hat 2014. This could lead to some interesting standoffs with governments and law enforcement wanting to read people's messages. From the article: "'We are working to design a key server architecture that allows for automatic discovery of public keys within Yahoo.com and other participating mail providers and to integrate encryption into the normal mail flow,' Stamos said."
"Metadata" is a media buzzword designed to make you feel good about having your data monitored. They're still monitoring your conversations. Stop buying into their talking points. The headers of your e-mail are as much your data as the body of the e-mail.
"Tell me doctor, with all of your defenses, are there any provisions for an attack by killer bees?"
Where is the private key stored? These are web mail services and if that's going to be easy to use, the key must travel with the user, and how is that going to work securely? Or are they going to store people's private keys on their own servers? If so, wouldn't that almost completely defy the purpose? If intelligence agencies or more usual evil does have access to the mail servers, or user accounts wouldn't they also have pretty much access to the key store servers too? Could someone with more knowledge into how this might work please sort this out for me.

Yahoo mail improved dramatically after Marissa Mayer became CEO. It seems to me that they are actually trying to be more like Gmail, and it shows in a positive way. They still fall short, but as a longtime Yahoo mail user I'll take what I can get. At least their recent improvements are much better than your characterization, for sure.
Now all I have to do is get my father, my mother, my sister, my half-sister, my grandmother, my wife, and my assorted friends to learn what PGP is and how to read the emails I send them.
This kind of functionality would be enough for me to switch mail providers.
Yes, yes, it can always be done manually, but I have a lot of friends that aren't as tech savvy as I am. Generating a key, keeping the private one somewhere safe, copying text from the PGP application, pasting it correctly, copying incoming text, pasting, decrypting, etc., etc., it's all a pain in the butt for the typical computer user.
If Yahoo can manage to implement this correctly so that it is safe AND easy to use that's a big deal.
Love sees no species.
Key management’s the thing here of course. If it’s on their server, NSA has it, etc. There are ways the key could be encrypted on server, decrypted only locally etc. Most of those have myriad ways the key could be mis-handled, leaked, etc.
That said, I’m kind of leaning towards this being a good thing, even if its implementation isn’t 100% paranoid geek approved secure. Ultimately if the NSA wants to read YOUR stuff, they’re going to (see: $5 wrench). If we assume Yahoo manages to implement this such that key retrieval is at least inconvenient (for $ufficiently large value$ of inconvenient) to anyone other than the account owner, then it should at least complicate NSA’s blanket “read all the things” approach. If it tips the balance back to the point that they actually have to expend more resources than your grandmother’s chocolate chip cookie recipe is really worth, then *maybe* they go back to only reading very interesting people’s emails without a warrant rather than reading everybody’s. I guess that’s worth half a point?
More importantly, if it manages to turn the seething mob of luddite Yahell users onto the fact that encryption is a thing, and explains to them why they want this thing, maybe the “winning hearts and minds” gambit is worth something to the world as a whole, even if the individuals’ email isn’t NSA-proof. Right now most mothers & grandmothers either have no clue what encryption is, or think it’s something only used by hackers, ter’ists, pr0n, criminals, etc. “Them” in other words. If Yahoo manages to convince a sizable portion of the voting public that privacy has worth, and encryption is a way to ensure that privacy, I think that’s a worthy outcome even if the encryption has flaws. Maybe that opens the door to conversations about the difference between effective and ineffective encryption. Maybe it even brings it closer to socially “normal” for someone who knows what effective encryption is to encourage others to use it without being assumed to be a nutcase or worse.
I hate to advocate selling snake oil, but there *are* an awful lot of squeaky snakes around. Maybe the right salesman can convince enough of the populace they need encryption, then we can worry about offering really good encryption for those adequately equipped to work with it.
It didn't but yahoo is a webmail provider and webmail kinda implies that the provider will either be storing the key or at the very least be able to access it by tweaking some javascript a litte.
The reason PGP is difficult for the plebs is that secure encryption requires you to take responsibility for your own key management and ensure to the best of your ability that the key does not leave devices you control (if you are really paranoid you don't even put it on an internet connected machine). If you leave key management up to a third party then your whole security becomes dependent on them.
note: i'm known as plugwash most places but i screwd up registering that here somehow in the past and now can't register
It's implied by the fact that it's webmail. Does your browser have an OpenPGP library? Does it check all the Javascript that it downloads and executes, against some repository's whitelist? You have to assume the key isn't handled safely, unless you can answer Yes to these questions. And a lot of webmail users expect the server to be able to search and that's obviously impossible unless the server can read, so it's not like the unsafeness stems just from potential trickery.
That said, the more interesting question is what social effect this might have. Even "bad" use of OpenPGP could start conditioning more people to being familiar with, tolerating, expecting PGP. Get into a better frame of mind, and better habits can come later. And with good habits, some security could eventually emerge. The security wouldn't be there for Yahoo webmail users, and yet some users might end up having Yahoo webmail to thank for it.
And let's face it, the barriers to secure communication are almost entirely social; we choose to have insecure communications. Anyone who is working on that problem is working on The Problem.
