Which mildly concerns me also, however it's in Beta so I suspect when 1.0 lands it'll be "additional disk space" plus additional features. Besides, the threat model is pretty transparent (content is invisible but senders/recipients/times all visible to server owner) and the client is open source and runs on a vetted crypto-scheme. The server is not open (yet?) but the documentation on the github makes the entire protocol very clear, so re-implementing would be time consuming but straightforward. Implementing a third-party server that federates, and extending the code to allow for cross-domain messages could make this a nice websocket-based standard replacement for email that's crypto-first, at last. In the mean-while, I'm happy to use Nadim's server and see where he takes it. On 14/01/15 15:10, Bill St. Clair wrote:

Has Cloudflare made any statements about whether they log traffic and/or hand over data to governments?
Well, anyone with a brain knows they do, and that statements from a US company are meaningless because nobody wants to go to jail over an NSL. What a top-level observer can see (AFAIK) is who's logged in, probably what their username/keyID is, and how much they're talking to the server. Because peerio uses miniLock formatted messages, the potential exists for minimal-knowledge service, but from the github docs it seems the server maintains an entry for which user is allowed to access which encrypted files, and therefore reveals to an observer who's the recipient. So, it's a metadata-rich service, little better in that regard than email.. although the encryption is pretty well designed and unless you set up a "PIN" there's no permanent storage of private keys even on your computer, so it's also quite secure when crossing borders. Also, there is a feature that clearly relies on compliant clients, where you can delete files from the server including copies sent to clients. Obviously if the attached files are downloaded from the system, this can't reach them, but it will destroy any "authenticated" copies of the messages from the server, if it works (you're trusting the server). OPSEC wise, this is a nice feature because it means you can clean up after yourself and keep the authenticated-data-at-rest on either end of a conversation to a minimum.

So it would be prudent to use pseudonyms, and to access via some mix of VPN(s), JonDonym and Tor (according to ones need for anonymity vs speed). And using devices with removable local storage, there would be no traces to be inspected by adversaries. Cool. But still, how is peerio more secure spideroak, for example?

Well, I use my real name in most places and communicate a lot with real-world friends and family by email, su using Peerio is therefore a step up in security for me even if I continue to go by my usual name and use my usual IPs. If you need hard anonymity, this is only a marginal gain over regular email because metadata (when, who, how, where) is a significant threat to anonymity. So yea, use a burner email when setting up a peerio account (no longer required after setup, probably a throwback to email-as-salt in miniLock plus contact discovery by known email address), then use through Tor (do research whether websockets are tor-safe?).
Cool. But still, how is peerio more secure spideroak, for example?
Spideroak appears to be more about file storage and sync, whereas Peerio seems to me to simply be a better approach to server:client email. It's down to the bone: message-passing with attachments, and a nice UI. As a crypto-app, it's targeted at the mainstream, and people who interact with the mainstream. People on this list will have better, more secure ways of communicating, but Nadim (to his credit) excels at making crypto-apps that can appeal to normal users while adding a significant privacy. It's an easier sell from "us" to "them". On 14/01/15 21:52, Mirimir wrote:

Since this is mostly for synchronous communication, you can inflict jabber+otr, which has all the benefits you mention above.
Who said synchronous? It's a chatlike, but this is server-hosted async message and file storage. Also, the failure of xmpp/jabber to attract the masses in the last decade is no accident. On 15 January 2015 12:12:26 GMT+00:00, Nikos Roussos <comzeradd@fsfe.org> wrote:

What a top-level observer can see (AFAIK) is who's logged in, probably what their username/keyID is, and how much they're talking to the server.
Because peerio uses miniLock formatted messages, the potential exists for minimal-knowledge service, but from the github docs it seems the server maintains an entry for which user is allowed to access which encrypted files, and therefore reveals to an observer who's the recipient.
So, it's a metadata-rich service, little better in that regard than email.. although the encryption is pretty well designed and unless you set up a "PIN" there's no permanent storage of private keys even on your computer, so it's also quite secure when crossing borders.
So it would be prudent to use pseudonyms, and to access via some mix of VPN(s), JonDonym and Tor (according to ones need for anonymity vs speed). And using devices with removable local storage, there would be no traces to be inspected by adversaries.
Cool. But still, how is peerio more secure spideroak, for example?
Also, there is a feature that clearly relies on compliant clients, where you can delete files from the server including copies sent to clients. Obviously if the attached files are downloaded from the system, this can't reach them, but it will destroy any "authenticated" copies of the messages from the server, if it works (you're trusting the server). OPSEC wise, this is a nice feature because it means you can clean up after yourself and keep the authenticated-data-at-rest on either end of a conversation to a minimum.
How about Pond as email replacement?
I've looked at Pond long enough to see that it calls upon Tor for most of the anonymity heavy-lifting, and that it is clearly targeted at technical users. Most of the people in my life who I speak privately to are not technical. I don't think trivial UX is near in Pond's development roadmap.

Keybase could have been a great way to encourage PGP uptake among normal people years ago when things were accepted to be difficult universally, but PGP's days are behind us. PGP makes a good way to sign code but remains a terrible way to communicate securely, because although it's "uncrackable" when used correctly, it's very easy to accidentally screw up using PGP on either end of the conversation. Also, the lack of PFS ignores parts of the modern threat model that were speculative when PGP was created. Suffice to say that, even ignoring the issues with Keybase encouraging key escrow by "allowing" or encouraging key upload (!!!), I don't think it helps. Perhaps as a basis on which to build a web-of-trust that can be transposed into newer cryptosystems, but the key escrow part makes falsification of trust a real possibility.

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 tl'dr Look... Cathal, I do like what you've done in the tiny realm of code ~ short, simple, and to the point, some examples being: Deadlock ~ dead simple encryption https://pypi.python.org/pypi/deadlock P2P, serverless microstatus system in 30 lines of pure python https://github.com/cathalgarvey/tinystatus (slooooowwwwww claaaaaaaappssssss) So with that out of the way, I have to say, though, your criticism which has appeared on my TL before of PGP is in my view, unwarranted, because, GnuPGP just aren't getting the funding need(ed) to get what should be done, done. It's been done essentially by one person. And frankly they could use a bit of help in getting out the word. Here's a thoughtful post from bytemark on this subject: (Please read it) https://blog.bytemark.co.uk/2014/12/31/gnupg-funding-drive (from Dec. 31, 2014) Then go on to read this thing: https://gnupg.org/donate/index.html As you see they accept all kinds of payment vehicles (and also bitcoin is one of them) And now here's the kicker: This two-person team which they are trying to get funded, IS NOT FUNDED! Take a look here: https://gnupg.org/index.html Again: NOT. FUNDED. And yes, interfaces like Keybase.io _are_ the future (I've been playing around with it and currently have it in my signature, though I use a different key block (not keybase) for people to use for to import in association with my e-mail), because they make it easier for a larger number of people to access keys either through something like keybase service where they host keys, or through a CLI where you hold all that closely. Merkle tree, blockchain, etc. But this begins in my view with a strong froundation, which we have from the work which was done from Gnupg. (In fact, Keybase.io, and any business like it in the future, relies on Gnupg.) If I was rolling in dough ($$) right now I would dump a giant fat amount of 86,000 € that they are missing so that they would be able to get going on the Gnupg second developer's work right away. So... enough of the rambling on, can someone who knows someone who has benefited from this economic ups and downs, please forward this e-mail on to them and ask them if they'd be willing to contribute to https://gnupg.org/donate/index.html I have absolutely zero financial interest in seeing this happen but I know it would help make a better world. - -O Cathal Garvey:

OK, I'll bite :) | 1. Downgrade Attack: The risk of using it wrong. ... | The mere existence of an e-mail address in the process is a problem. ... | 2. The OpenPGP Format: You might as well run around the city naked. ... | 3. Transaction Data: Mallory knows who you are talking to. Well, correspondents ought to: 1) always use pseudonyms if they care about attribution; 2) avoid meaningful subject lines; and 3) use VPNs, JonDonym and Tor to obscure network connectivity. Given that, why care that adversaries see OpenPGP? | 4. No Forward Secrecy: It makes sense to collect it all. So what? Just secure your shit properly! | 5. Cryptogeddon: Time to upgrade cryptography itself? Smart folk who care about attribution never put anything online that links their pseudonyms to their real names. Just sayin'. And they rotate their pseudonyms periodically. So stored messages go stale within a year or two, tops. | 6. Federation: Get off the inter-server super-highway. That's prudent for stuff that matters. But OpenPGP is still good within the transport layers. | 7. Discovery: A Web of Trust you can't trust. I've never used WoT, and tend to agree. WoT is especially impractical because I don't at all mix meatspace and online activity. I am starting to like Keybase, however. I don't worry very much about sharing publicly who my conversation partners are. I always use pseudonyms, and so do many of my conversation partners. Sometimes we all use multiple pseudonyms, just for fun :) | 8. PGP conflates non-repudiation and authentication. Again, use those pseudonyms! | 9. Statistical Analysis: Guessing on the size of messages. Having my pseudonyms profiled doesn't worry me greatly. | 10. Workflow: Group messaging with PGP is impractical. Why bother? Just set up a Tor hidden-service forum, or whatever. | 11. Complexity: Storing a draft in clear text on the server I use both IMAP and POP, and I've never seen plaintext drafts stored on the server. I believe that Enigmail's "convenient encryption settings" (in particular "auto send encrypted") prevent this, as long as you have the public key of the person whom you're drafting a message to. It's also prudent to switch to manual mode, and to set "confirm before sending" to "Always". | 12. Overhead: DNS and X.509 require so much work. Who's enslaved? One uses whatever tools are appropriate. | 13. Targeted attacks against PGP key ids are possible This is an advantage of Keybase. Then we're not depending on the KeyID, or even on the fingerprint, but rather on an identity that's multiply and independently authenticated. | 14. TL;DR: I don't care. I've got nothing to hide. I hide in many ways, and don't depend on message encryption ;) My "preferences, habits and political views" are fragmented among multiple unlinked personas. How to do that is one of my key soapbox topics ;) | 15. The Bootstrap Fallacy: But my friends already have e-mail! Again, it's a tool. But of course it's not the only tool.

1) third party broad spectrum surveillance from cromnibus.
Metadata wise this is a real problem with the system as currently envisaged, but would frankly apply to any hosted-ciphertext platform.
"Instead of dealing with key storage, Peerio generates a user’s private key from his passphrase every time he or she logs in." from: http://www.wired.com/2015/01/peerio-free-encryption-app/ That may or may not accurately describe the process, however.
This is correct; Peerio uses MiniLock under the hood for crypto, and private keys for minilock are generated deterministically; when you "log out" the key is not stored permanently (although JS can't wipe RAM so a closer-to-metal client would be nice).
3) Free, or not? Apparently there is a paid option, and a free option initially at launch, there is a open source repository on github. To the extent that the crypto is tied to a company (kind of assumed, if there is a paid option and there is an LLC or something like that), then the corporation is vulnerable to being shut down or at the very least "conditioned" ~ being told what to do when "crypto licenses" come
They're in free beta, my understanding is they'll charge for storage. There's not much that can be done to wind back the crypto as it's all client-side, and if their server were shut down, as I've mentioned before, the server behaviour is all documented on Github. One useful way to look at this: GPG is what most recommend for crypto, but it's metadata rich and requires usually closed platforms to distribute ciphertexts (you may not use Yahooglesoft but your recipients will usually). In recent discussions on this list, the use of a centralised key distribution *company*, keybase, has also been accepted to some extent (though I'm not too happy..). miniLock is designed as a spiritual descendent of PGP with many use-case improvements and a much simpler threat model. You can use miniLock instead of GPG across email, and it will leak less metadata than GPG by virtue of using ephemeral keys that don't directly link a message to its sender or recipients. Peerio is like Gmail plus Keybase for miniLock; it serves exactly those purposes. We would all (me emphatically included) rather if it ran on a store/forward PGP mixnet, provided it retained good UX to appeal to the masses, but right now, it's a centralised service that hides the content and format of communications while unavoidably having total access to the metadata of from who, to whom, and when. So yea, centralised and closed ain't good. They are the warts I'd like to see fixed with a federated and/or mixed backend. But the frontend is just as open as GPG is, and we already generally endorse the use of open front-ends to work around closed back-ends. I may be motivated soon to re-implement miniLock in Go as a learning excercise (still a Golang noob here), in which case it could be a short hop from there to a server/client implementation for Peerio, too. But, I'm not committed to that yet and have written not an `iota` of code yet, so by all means beat me to it. On 20/01/15 07:07, odinn wrote:

What a top-level observer can see (AFAIK) is who's logged in, probably what their username/keyID is, and how much they're talking to the server.
Because peerio uses miniLock formatted messages, the potential exists for minimal-knowledge service, but from the github docs it seems the server maintains an entry for which user is allowed to access which encrypted files, and therefore reveals to an observer who's the recipient.
So, it's a metadata-rich service, little better in that regard than email.. although the encryption is pretty well designed and unless you set up a "PIN" there's no permanent storage of private keys even on your computer, so it's also quite secure when crossing borders.
So it would be prudent to use pseudonyms, and to access via some mix of VPN(s), JonDonym and Tor (according to ones need for anonymity vs speed). And using devices with removable local storage, there would be no traces to be inspected by adversaries.
Cool. But still, how is peerio more secure spideroak, for example?
Also, there is a feature that clearly relies on compliant clients, where you can delete files from the server including copies sent to clients. Obviously if the attached files are downloaded from the system, this can't reach them, but it will destroy any "authenticated" copies of the messages from the server, if it works (you're trusting the server). OPSEC wise, this is a nice feature because it means you can clean up after yourself and keep the authenticated-data-at-rest on either end of a conversation to a minimum.
