ProtonMail Adds Tor Onion Site To Fight Risk Of State Censorship (techcrunch.com)

ProtonMail now has a home on the dark web. The encrypted email provider announced Thursday it will allow its users to access the site through the Tor anonymity service. From a report: Swiss-based PGP end-to-end encrypted email provider, ProtonMail, now has an onion address, allowing users to access its service via a direct connection to the Tor anonymizing network -- in what it describes as an active measure aimed at defending against state-sponsored censorship. The startup, which has amassed more than two million users for its e2e encrypted email service so far, launching out of beta just over a year ago, says it's worried about an increased risk of state-level blocking of pro-privacy tools -- pointing to recent moves such as encryption messaging app Signal being blocked in Egypt, and the UK passing expansive surveillance legislation that mandates tracking of web activity and can also require companies to eschew e2e encryption and backdoor products. The service also saw a bump in sign ups after the election of Donald Trump as US president, last fall -- with web users apparently seeking a non-US based secure email provider in light of the incoming commander-in-chief's expansive digital surveillance powers.

    I've been a user since their beta days, and I can say the service generally works well with a few exceptions in the UI. Most notably it's slow, very slow, and the TOR interface seems to be even slower. Combine that with lack of features (like mailbox purge) and mandatory space constraints it makes the service very hard to use for day to day messaging needs. That all said, I really do like the service and find the entire concept of browser based encrypted UI, with encryption handler happing within the browser itself very interesting and a neat way forward (possibly for larger sites like gmail in the future).

      Why not use PGP with a real e-mail client? ProtonMail doesn't support keyservers or downloading pubkeys to a keyring which adds a few annoyances to the process of sending/recieving ProtonMail with someone using PGP on a real client.

      Also if your pubkey is newer than this one:

      pub   1024D/C9E6D134 1999-09-26

      PGP with a normal email client does nothing to protect your "metadata", i.e. who you are, who you communicate with, the subject line, date, etc. All you can do is use TLS/SSL and hope that the email servers communicate with each other encrypted without NSA backdoors (i.e. they have a copy of the TLS/SSL private key).

    There are two main reasons why Subject lines in ProtonMail messages are not end-to-end encrypted.

    Not Standards Compliant â" ProtonMail adheres to the OpenPGP standard which largely respects the SMTP protocol. In PGP, the subject line is part of the header packet which is not end-to-end encrypted.

    That only applies to ProtonMail e-mail messages. As far as I can tell, their special "ProtonMail messages" between ProtonMail users have their metadata protected.

    Besides, while metadata does show IP addresses, subject and whatnot it still isn't as important as the message body. For example you could have something like this:

    Header
    From: CommodoreChimichanga@pipedash.com
    To: BuckarooNeville@pipedash.com
    Subject: Cat videos

    Message body:

    -----BEGIN PGP MESSAGE-----
    Version: GnuPG v2

    owE9jTEOwjAQBKnp+ME+ILJEQ0+DEiFEB7QXcyQWts/yGVBKPsYH+BRGQnRbzOy8

    -----END PGP MESSAGE-----

    That's encoded with gpg2 -a --store so it's not really encrypted, it says:

    I really don't like combining my encryption layer with the transport layer. Too easy for stuff to get compromised. Even if the company has good intentions, an agency like Interpol leaning on them with the choice of putting in a backdoor or everyone in the company going to jail for conspiracy/collusion charges can cause issues.

    My recommendation: Use a PGP reader and a secure transport mechanism. PGP applications are pretty easy to obtain on all platforms. Then, use a trustworthy transport link. The closest analog to this would be sending critical stuff via registered mail. The Post Office uses two keys and signatures every place the message goes, and even then, only the receiver and the sender have/had access to what is inside the envelope.

    Well yes if you are living in an oppressive regime and want to have total deniability you DO have to use something like ProtonMail over Tor. And even then they are still vulnerable to the Swiss government requesting what info they have. Not only that, but a US government agency invented Tor in the first place.

    But...even the puissant 3-letter agencies of the US with all their resources are not omnipotent/omniscient. We still have mobsters, fraudsters, drug dealers, car theft rings, etc etc. There's too much metadata to go through. What you'd want to do in most circumstances is not stick out from the pack.

    In the Revolutionary example you linked to, one of the reasons Revere was able to be singled out as a "bridge" was the small membership of the various organizations and the fact it was easy to find out WHO was a member. Part of that was due to class stratification and lack of literacy.

    One thing we can do now is be one of those people who connects to EVERYONE. Be one of those people spamming game invites on Facebook, friending everyone and their cat, joining every social network.

    Also we can vary our communication methods and use unconventional networks.

    For example the virtual world Second Life has in-world items called "Notecards" they can contain any text and you can copy/paste to and from them. One can also script objects to give out Notecards, even to specific people, meaning I don't actually have to directly contact you in Second Life to communicate with you. I can set up a "dead drop"

    Or we could SSH into sdf.org and communicate there. In fact we could e-mail each other using SDF's own pine or mutt clients between SDF.org addresses and not have our e-mails transit to any other mailserver.

    Or one could self host a temporay IRC server with SSL no less.

    People could say, head to a library or starbucks, turn on bluetooth, and send encrypted messages/data to each other. They wouldn't even have to talk to each other or sit near each other.

    Or using the above example they could do the same thing but use steganography to disguise their messages as cat pictures.
