Author here. Happy to answer any questions :)

Good project. Why aren't you using Kickstarter or Indiegogo?

geertj17• 13 years ago

Kickstarter is US/UK/Canada only. Being Dutch and resident in Italy it would not work.

I hadn't really looked at Indiegogo before I was too far along doing my own site. In the end it was relatively simple. I'll open source it at some point.

I have a KeePassX db in a git repo I clone on all my hosts plus two backup remotes.

Why would Bluepass be any better than my current setup? I already have P2P secure synchronization (via git+ssh), full control over my data and everything is based on portable FOSS.

geertj17• 13 years ago

A few things:

* Bluepass does push synchronization. So you wouldn't need to manually sync.

* It would work on smartphones / tables too.

* Are the remote git repos under your physical control? If not then your setup is vulnerable to a dictionary attack on your password / passphrase.

* The Bluepass database is set up such that it can resolve conflicts due to concurrent updates (actually it's an append-only graph of parent->child nodes with a algorithm that selects the most likely lineage in case of conflict).

[Edit: some clarifications]

Any plans to support Yubikey for authentication? That alone would earn my backing.

geertj17• 13 years ago

Yubikey could be interesting for protecting the local vault. I haven't looked into it yet on how easy it is to do, but it is interesting and I will look into it. I cannot make any guarantees yet though.

MartinMond• 13 years ago

Have you considered supporting cloud sync? It should be possible to make it secure and it would be a huge convenience.

geertj17• 13 years ago

I did consider it, and the Bluepass sync protocol has an option for a node type without an encryption key. Such a node is merely "reflector" of traffic, which can be useful in case you have two disjoint sets of devices that are never on the same LAN.

This could be later addition. However it does decrease the security slightly because now you have to assume that others now have access to your encrypted data. It is still a lot better than the alternatives because still no dictionary attack is possible, you'd have to break RSA to get to it.

I've never understood why password managers use browser plugins. It should be an application agnostic overlay that pastes selected passwords into the currently selected textbox.

I'm working around that at the moment with a combination of Emacs, the Mac keychain and Alfred.app - it's not beautiful though.

What are your plans for this?

bigiain3• 13 years ago

FWIW, I think the browser plugins that 1Password implements are the "killer feature" - it notices you registering/logging-in to most websites, and prompts you to save the password. This reduces enormously the temptation to "just use an easy-to-remember reused-everywhere" password - I can randomly mash keys and have it automatically remember 25+ char passwords for me.

That _rocks_.

geertj17• 13 years ago

My plans regarding browser plugins was to have a small icon inside a <input type="password"> that can generate a new password, or would allow you to select the password if you already stored it and it's not clear which one to use. Otherwise the field should be automatically filled in.

How do you activate the paste in your setup? Is there some kind of global key combo for this?

Zecc• 13 years ago

Not a question, but a pet peeve. You have a typo on your homepage. Search for 'synchronziation'.

Also, please don't have text that looks like a hyperlink if it's not (even if it is a placeholder), specially if you then have hyperlinks that look the same.

Other than that, good luck on the project. It seems promising.

reedlaw5• 13 years ago

I'm very excited to see this. I've been using KeePass2 on Linux and it's a pain to sync with my Android phone. I tried setting up OwnCloud to share the key file but even using that causes too much friction for me to be willing to frequently sync.

In your FAQ you say:

"What do I get when I fund you? Once the software is ready, you will get unlock codes for the mobile versions for the amount you funded. As a special appreciation for being an early customer, these codes not expire and will unlock the mobile versions for life."

But you don't specify a price for the mobile versions. Also, will the mobile versions be GPL'ed?

Very happy to see you take Bitcoin as a funding option.

geertj17• 13 years ago

Hi, it's mentioned in the FAQ, little bit further down.

The mobile versions will be somewhere between $5 and $10. As a perk for funding Bluepass, whatever the price turns out to be, your version will include unlimited free upgrades.

The source of the mobile versions will be available, but for the success of a project, a recurring revenue stream is required to maintain them. The mobile platforms change a lot, and there are not many examples of open source projects that can successfully provide productized versions for these mass market consumer platforms. That is why I cannot commit at this point that the license will allow redistribution on an app store. This means it would not be an OSI style license.

m0nty2• 13 years ago

I use keepass on PC and Android, and sychronise using bittorrent sync. No issues.

pampa2• 13 years ago

Does it support the keepass db format?

geertj17• 13 years ago

At this point it does not. But a feature to import a keepass DB into the Bluepass native format is in the plan.

As someone who is a big supporter of Firefox Sync [0]:

What will this provide me over Firefox Sync, which has a built in encryption layer on their (admittedly cloud) service? I can pull their code and host my own Firefox sync server, and someone has written a special PHP-based version for inclusion into OwnCloud. So, what is so special here except the use of buzzword P2P? (See next question below.)

How will you do to P2P without some kind of centralized bootstrapping service with the prevalence of NAT and people who do not know how to port-forward? (I just saw the Github repos, so I will examine this myself in a bit.)

UPDATE: It would appear you are using mDNS and/or Zeroconf [1] to handle this? I am still not sure how this will ease the NAT and/or syncing over public Internet.

Why should I trust you? What have you done other than this project? Not to be increasingly blunt, but you are not the Mozilla Foundation and your Github repos do not show much other than work on co-routines and AD service wrappers. That is useful to me, but I would like to see more security work and knowledge of crypto libraries if I trust you with password manager code. What else do you work on? Your blog does not show me too much, and I cannot find much mention of you to warrant 60,000 USD for such a project. I am correct in seeing you a Marketing/Product Manager? Sorry to be harsh, but honestly I think most of HN would be worried about these points.

UPDATE: Ok, maybe I was a little too harsh; you do seem to have some more experience than I had previously estimated, given some Googling and your Linkedin profile, if legit. [2]

reedlaw5• 13 years ago

I'm a big fan of Mozilla as well, but can Firefox Sync handle credentials other than for web? I use KeePass2 to store a lot more than just web username/passwords. Also, I like to keep my password database separate from my browser for security reasons.

As far as trusting this project, it is GPL and you are free to inspect it. I don't think being part of the Mozilla Foundation somehow guarantees secure code. If the author wants $60,000, he is free to ask for it.

geertj17• 13 years ago

Heh, well thanks for the honesty :)

How will you do to P2P without some kind of centralized bootstrapping service with the prevalence of NAT and people who do not know how to port-forward? (I just saw the Github repos, so I will examine this myself in a bit.)

The P2P is done over local networks only. It uses multicast DNS for service discovery. Bluepass syncs between your own devices only. As long as the devices occasionally share a (W)LAN, it will work.

Why should I trust you? What have you done other than this project? Not to be increasingly blunt, but you are not the Mozilla Foundation and your Github repos do not show much other than work on co-routines and AD service wrappers. That is useful to me, but I would like to see more security work and knowledge of crypto libraries if I trust you with password manager code.

Well, everybody has to start somewhere. I do believe that I have enough experience with crypto to be qualified here. I've got a physics degree and did a lot of maths. And I read Schneier and Wenbo Mao's book cover to cover. Also note that I'm not using any proprietary algorithms. This is all OpenSSL wrapped algo's that I'm using from Python.

But in the end, what should give this the right credibility is that the source code is up on Github, together with my intention to grow a community that can review the crypto. If there is something not right, which can always happen of course, then it will get out sooner or later.

What else do you work on? Your blog does not show me too much, and I cannot find much mention of you to warrant 60,000 USD for such a project. I am correct in seeing you a Marketing/Product Manager? Sorry to be harsh, but honestly I think most of HN would be worried about these points.

This is not related to my day job. I would say have a look at the code, and decide for yourself if you like the code. I don't think being a product marketing manager in the day is mutually exclusive with being able to write good code.

The calculation of the funds is rather straightforward: $10k for each of the platforms that need work: iOS, Android, Chrome, FF, Mac and Windows.

geertj17• 13 years ago

Regarding the question around Firefox sync: even if you use your own server, you are sending senstive data that is encrypted with a password or passphrase over the Internet. This opens you up to dictionary attacks now, and if the communications are intercepted, far into the future.

geertj17• 13 years ago

I confirm that [2] is my legitimate Linkedin profile :)

tigerweeds• 13 years ago

this is exactly what I've been looking for. I was thinking of using a small truecrypt container with btsync but it wouldn't work well due to container size being always the same, sync being possible only after unmounting the TC container and so on.

antirez• 13 years ago

I'm currently using a truecrypt tiny volume inside Dropbox, works but it is not really ideal. Conflicts resolution and a very long password to remember for the volume, that's the only way I can protect the data when it is synched on the Dropbox servers.

geertj17• 13 years ago

Exactly. By default Bluepass uses a long password as well to protect the local database. However, you can opt to choose a shorter password, or no password at all. In this case you are still protected by:

* The physical security of your device. Unless someone gets access to your device, you are safe.

* The fact that the sync traffic goes over your local network only.

* Even if someone managed to sniff your local traffic, all synchronization requests are encrypted by each node's unique 2048-bit RSA key. No dictionary attack is possible - you'd have to break RSA.

bigiain3• 13 years ago

I've got EncFS encrypted filesystems on Dropbox, BTSync, GoogleDrive, and Jottacloud (a non-US based cloud storage provider). It's been working fine over the last month or so of testing. In MacOSX, I've got both EncFS over FUSE and the commercial BoxCryptor packaged version happly working together. I've got Ubuntu 9 & 12.04LTS, ARCH Linux on a RaspberryPi, and iOS on my phone and iPad all syncing some or all of those EncFS containers and successfully reading/writing them. I haven't tried, but I have no reason to doubt BoxCryptor will happily read/write those filesystems on Windows and Android.

One thing I particularly like about this setup, is that I can have encrypted data synced to a machine that doesn't have the decryption key (or even software) on it – my media server and a machine at work are "backing up" all that data without it being "exposed" even if a machine and disks get stolen/confiscated.

This is different to a truecrypt volume, in that the files are still discrete:

  [Bigs-MacBook-Pro:~/Dropbox/BoxCryptor-DB.bc] bigiain% ls -l
  total 7544
  -rw-r--r--@  1 bigiain  admin      625 12 Jun 10:59   !IMPORTANT BoxCryptor Information.txt
  -rw-r--r--@  1 bigiain  admin        0 12 Jun 11:07 Hmz6h72bplJbH1
  drwxr-xr-x@  3 bigiain  admin      102 12 Jul 18:01 QY7,wBj6mQwGV7OyD3Qbll8
  drwxr-xr-x  50 bigiain  admin     1700 23 Jul 22:21 WoVrJB-gyKVMm0
  -rw-r--r--@  1 bigiain  admin  3840262  6 Aug 09:40 Z8,UY5cp7Ux491OckZ9yXM2
  -rw-r--r--@  1 bigiain  admin    15364  7 Aug 21:25 nMrARYb-KDbdDj2

individual files can get synced as the change, without needing to re-sync the entire volume. On the downside, that means I leak some metadata, file sizes and modification dates, but not names or contents. I also lose the tryecrypt option of hidden volumes, but perhaps that's a plus in that they wont hit me with the $5 wrench insisting that there's _another_ password - even if there isn't…

Rygu• 13 years ago

I use 1Password with Dropbox. Can someone tell me whether I'm at risk, and should donate to this project?

geertj17• 13 years ago

You are at risk of a dictionary attack on your password / passphrase. You need protect it with a long, computer generated passphrase to be secure. I would say at least 128 bits of entropy. By being stored on Dropbox, you have to assume that the the "agencies" have access to your database. At some point, computing will advance enough to either brute force the encryption or find a weakness in it.

The safest option is to prevent 3rd parties from having access to your encrypted data in the first place. This is the approach Bluepass is taking.

jpalomaki2• 13 years ago

The entropy problem you can go around with by encrypting the data with a combination of pass phrase and a token file. For example KeePass supports these kind of combinations.

Obviously the token file would be something you don't put into cloud but instead store on each physical device.

mseebach• 13 years ago

Remember what you're protecting here: the keys to your data, not the data itself.

You're at risk from the US government, but it's unclear that a government that can compel Dropbox to hand over your database and then crack some pretty heavy encryption can't access the accounts you're protecting with those passwords in some other way.

The main adversaries, IMO, you're protecting against are non-government actors, and your setup should be completely adequate for those.

FWIW, I have the same setup, but with Keepass.

falk• 13 years ago

It's been reported that Dropbox is "coming soon" to PRISM.

DanBC2• 13 years ago

What are you protecting, and who are you protecting it against?

alan_cx• 13 years ago

How about:

"What are you protecting,"

Freedom

"and who are you protecting it against?"

The US(UK) government.

jpalomaki2• 13 years ago

One interesting option would be to bring this kind of P2P syncing to KeePass. This would benefit from all the features that are already build into KeePass.

geertj17• 13 years ago

Why not improve something existing is a valid question, and I did look into it.

The difficulty is that a P2P sync requires a completely difference design. Keepass is pretty much a frontend to an embedded database. A P2P node need to have its own network facing component that acts independently of the frontend, to relay messages, respond to pairing requests, etc. This is why Bluepass has a frontend/backend architecture. It is a lot easier to create such a different architecture from scratch.

reedlaw5• 13 years ago

IMHO KeePass is in need of a reboot. First, it's very confusing which version to use. KeePass 1.x (Classic), KeePass 2.x (Professional), or KeePassX (originally KeePass/L for Linux?). When I first tried them out, I settled on KeePass2 because it supported filling out browser forms in Linux. But it's a mono app with an ugly interface. With no built-in syncing support and no good syncing plugins either.

I hope this project can become a suitable replacement.

leke• 13 years ago

It combines broad platform support, peer-to-peer synchronization over local networks (never using the cloud)...

My god, the NSA has managed to turn "The Cloud" into a dirty word.

ams6110• 13 years ago

They really just exposed its inherent flaws.

reedlaw5• 13 years ago

Then I owe the NSA gratitude because I've been long wishing that there was more focus in the hacker community on building distributed systems as alternatives to data silos like Facebook and Google.
