  • Many encryption algorithms rely on the assumption that the factorizations of numbers in prime numbers has an exponential cost and not a polynomial cost (I.e. is a NP problem and not P, and we don’t know if P != NP although many would bet on it). Whether there are infinite prime numbers or not is really irrelevant in the context you are mentioning, because encryption relies on factorizing finite numbers of relatively fixed sizes.

    The problem is that for big numbers like n=p*q (where p and q are both prime) it’s expensive to recover p and q given n.

    Note that actually more modern ciphers don’t rely on this (like elliptic curve crypto).

    Encrypted DNS doesn’t solve everything. Handshake for TLS sessions is still in clear, you can usually see the SNI, and since we are talking about Wireless, usually this data is available to anybody who is in the vicinity, not just the network owner. This already means that you can see what sites someone is visiting, more or less. TLS 1.3 can mitigate some of this (for those who implement ESNI, but you don’t know that beforehand). Also TLS works until the user is not accepting invalid certificates prompts (HSTS doesn’t work for everything) and there are still tons of HTTP-based redirect (check mailing newsletters and see how many first send you to an HTTP site, for example) that can be used for MiTM attacks.

    A VPN moves the trust to a single provider that you can choose, which is much better than trusting every single WiFi network you can attach to and the people connected to it, I would say.

    Also if you pay for the VPN (I pay Proton), it’s not true that the company business is based on user data, they are based on subscriptions.




  • I read the post, hence my points. I am not really looking for answers, because I don’t have questions, I had observations. You on the other hand seem to have your whole opinion formed on this inaccurate post, and I would expect someone in your position to look for more perspectives, when you clearly are not. You seem instead on a crusade against the company (good for you), and even if all the post was true, because they spent too much on t-shirts, invested too much in AI products (that I repeat, are opt-in)? Because they don’t comply with a technicality of GDPR? Lol Ok, more power to you.

    Also, what I mean by a subscription is that I cancel it and I am done. I didn’t invest in it in any shape or form, what I paid I consumed already, there is no feeling of wasting previous investment in a running subscription.

    Judging from your attitude, your lack of content, your very annoying “homie”, your inability to address any point against the content of the article, I am guessing either you are the author and you are butthurt that is not taken as gospel, or you just have ulterior motives and you are here just to stir shit (instead of “spreading awareness”). Either way, I have already invested too much time writing responses to your silly comments. I will show you how good I am in avoiding the sunk cost fallacy and block you, despite the time invested in the conversation.

    Cya


  • I answered with more stuff in other comments, but you didn’t address any of that anyway.

    I personally have no brand faith, I am a happy customer and the moment the company doesn’t adhere to my principles I will dump it. There is no sunk cost as it’s a running subscription (you keep mentioning this, so I though I will say it).

    That said, if I see someone claiming they have a “blase” approach to privacy or they don’t care about it, I will point out that this is complete bullshit. Using the missing “download my data” feature to support this claim is outright pathetic.

    To be even more precise, as a socialist I don’t like many of Vlad’s ideas that tend towards libertarianism. That said, the company has a good amount of worker ownership, it operates on principles I currently respect and that are miles higher than the standard tech company. I am absolutely in favour of supporting positive business in a field where companies are disgusting on average, and in cases evil.

    Now, if you have anything else than childish arguments I am happy to discuss them. I have pointed to a number of inaccuracies in the article, there are outdated data (like the number of employees) and subjective views from the author. You are posting this article everywhere like it’s some kind of holy grail of gotchas, when it’s not. There are some good points (financial reporting exists, is not 100% transparent - which is not due, the amount spent for the t-shirts was IMHO not a great idea, etc.), but the fundamental points against the company are shacky at best. As I said elsewhere, all the shpiel about AI etc. is fully addressed in kagi own site where they clearly explain what they mean, for example. The features are actually pretty nice, even for someone like me who is not a fan of LLMs, and the results are quite accurate (the post author claims they are almost always wrong) from my experience.

    BTW my searches are unlimited :)




  • That article is quite dense with inaccurate information (e.g. they own a T-shirt factory), and a lot of guesses. There is no need to listen to a random guy idea about kagi’s AI approach when they have that documented on their site.

    Also, the “blase attitude to privacy” is because of a technicality of GDPR? (Not having the ability to download a file with your email address) I am a big fan of GDPR, and their privacy policy is the best I have seen (I read the pp of every product I use and I often choose products also based on it), so really I don’t care about the technical compliance to GDPR (I am not an auditor), but the substantial compliance.

    All-in-all, the article raises some good points, but it is a very random opinion from a random person without any particular competencies in the matter. I would take it for what it is tbh

    EDIT: To add a few more:

    • They achieved profitability (BTW, 2 years of operation and being profitable with 30k users, they really don’t know what they are doing /s)
    • Their price changed twice. It was raised once, and the change was reverted later on, with unlimited searches. For me that is a great sign, especially considering the transparency of telling exactly how much each search costs for them.

  • Agree on the versioning issue. In fact I mentioned that the issue is convenience here. It is also data corruption, but you probably are aware of that if you setup something like this. Manually merging changes is extremely annoying and eventually you end up forgetting it to do it, and you will discover it when you need to login sometime in the future (I used keepass for years in the past, this was constantly an issue for me). With any natively sync’d application this is not a problem at all. Hence +1 for convenience to bitwarden.

    However KeePassXC’s sync feature does sync the vault.

    How does it work though? From this I see you need to store the database in a cloud storage basically.

    For mobile I just give syncthing full permission to run in the background and have never had issues with the syncing on the folders I designate.

    I use this method for my notes (logseq). Never had synchronization problem, but a lot of battery drain if I let syncthing running in the background.

    Nothing else passes through it unless you opt into using relaying in case you have NAT issues.

    I guess this can be very common or even always the case for people using some ISPs. In general though, you are right. There is of course still the overall risk of compromise/CVEs etc. that can lead to your (encrypted) data being sent elsewhere, but if all your devices can establish direct connections between each other, your (encrypted) data is less exposed than using a fixed server.

    If you are paranoid, the software is open source and you can host your own relays privately,

    This would also defeat basically all the advantages of using keepass (and family) vs bitwarden. You would still have your data in an external server, you still need to manage a service (comparable to vaultwarden), and you don’t get all the extra benefits on bitwarden (like multi-user support etc.).

    To be honest I don’t personally think that the disclosure of a password manager encrypted data is a big deal. As long as a proper password is used, and modern ciphers are used, even offline decryption is not going to be feasible, especially for the kind of people going after my passwords. Besides, for most people the risk of their client device(s) being compromised and their vault being accessible (encrypted) is in my opinion way higher than -say- Bitwarden cloud being compromised (the managed one). This means that for me there are no serious reasons to use something like keepass (anymore) and lose all the convenience that bitwarden gives. However, risk perception is personal ultimately.


  • Few reasons, with the most important being convenience. Syncthing is going to see just a binary blob as the password storage is encrypted. This means it is impossible for syncthing to do proper synchronization of items inside the vault. Generally this is not a problem, but it is if you happen to edit the vault on multiple devices and somehow syncthing didn’t sync yet the changes (this is quite common for me on android, where syncthing would drain the battery quite quickly if it’s always actively working). For bitwarden on the other hand the sync happens within the context of the application, so you can have easy n-way merge of changes because its change is part of a change set with time etc.

    Besides that, the moment you use syncthing from a threat model point of view, you are essentially in the same situation: you have a server (in case of syncthing - servers) that sees your encrypted password data. That’s exactly what bitwarden clients do, as the server only has access to encrypted data, the clients do the heavy lifting. If the bitwarden server is too much of a risk, then you should worry also of the (random, public, owned by anybody) servers for syncthing that see your traffic.

    Keeshare from my understanding does use hosting, it uses cloud storage as a cloud backend for stateful data (Gdrive, Dropbox etc.), so it’s not very different. The only difference would be if you use your private storage (say, Synology Drive), but then you could use the same device to run the bit/vaultwarden server, so that’s the same once again.

    The thing is, from a higher level point of view the security model can only be one of a handful of cases:

    • the password data only remains local
    • the password data is sync’d with device-to-device (e.g. ssh) connections
    • the password data is sync’d using an external connection that acts as a bridge or as a stateful storage, where all the clients connect to.

    The more you go down in the list, the more you get convenience but you introduce a bit of risk. Tl;Dr keepass with keyshare/syncthing has the same risks (or more) than a Bitwarden setup with bitwarden server.

    In addition to all the above, bitwarden UX is I would say more developed, it has a better browser plugin, nice additional tools and other convenience features that are nice bonuses. It also allows me to have all my family using a password manager (including my tech illiterate mom), without them having to figure out anything, with the ability to share items, perform emergency accesses etc.


  • I can’t really make an exhaustive comparison. I think k3s was a little too opinionated for my taste, with lots of rancher logic in it (paths, ingress, etc.). K0s was a little more “bare”, and I had some trouble in the past with k3s with upgrading (encountered some error), while with k0s so far (about 2 years) I never had issues. k0s also has some ansible role that eases operations, I don’t know if now also k3s does. Either way, they are quite similar overall so if one is working for you, rest assured you are not missing out.
