-* Why use self-signed certificates?
292
-Almost everywhere on the web you will read that self-signed certificates are worthless. They bring up /scary-scary looking/ browser warnings and gurus will advise you not to use them. Self-signed certificates are quite useful though. What the scary warnings mean - and it would be good if they explained this more clearly - is that you have an encrypted connection established but there is /no certainty about who that connection is with/. They probably will protect the content of your communications from passive bulk interception - such as the tapping of under-sea cables.
293
-
294
-The current strategy on this system is to typically create self-signed certificates during the initial installation but also to have the ability to easily convert those to LetsEncrypt certificates via the security settings on the administrator control panel.
295
-
296
-You might say, /"but surely LetsEncrypt is a single point of failure!"/, and you'd be right. Maybe at some point in future LetsEncrypt is no longer a thing, or no longer considered sufficiently secure. That's why building in total dependence upon one organisation is a bad idea, and it's still possible to have self-signed certs as a fallback option.

 [[https://cryptostorm.org/viewtopic.php?f=63&t=2954&sid=7de2d1e699cfde2f574e6a7f6ea5a173][That pledge]] is utterly worthless. Years ago people trusted Google in the same sort of way, because they promised not be be evil and because a lot of the engineers working for them seemed like honest types who were "/on our side/". Post-[[https://en.wikipedia.org/wiki/Nymwars][nymwars]] and post-[[https://en.wikipedia.org/wiki/PRISM_%28surveillance_program%29][PRISM]] we know exactly how much Google cared about the privacy and security of its users. But Google is only one particular example. In general don't trust pledges made by companies, even if the people running them seem really sincere.

 Yes. The minimum requirements are to have some hardware that you can install Debian onto and also that you have administrator access to your internet router so that you can forward ports to the system which has Freedombone installed.

 When the project began in late 2013 the FreedomBox project seemed to be going nowhere, and was only designed to work with the DreamPlug hardware. There was some new hardware out - the Beaglebone Black - which could run Debian and was also a free hardware design so seemed more appropriate. Hence the name "Freedombone", being like FreedomBox but on a Beaglebone. There are some similarities and differences between the two projects:

 The FreedomBox project supports Raspberry Pi builds, and the image build system for Freedombone is based on the same system. However, although the Raspberry Pi can run a version of Debian it requires a closed proprietary blob in order to boot the hardware. Who knows what that blob might contain or what exploits it could facilitate. From an adversarial point of view if you were trying to deliver "bulk equipment interference" then it doesn't get any better than piggybacking on something which has control of the boot process, and hence all subsequently run processes.

 Before you run screaming for the hills based upon whatever scare story you may have just read in the mainstream media there are a few things worthy of consideration. Tor is installed by default on Freedombone, <i>but not as a relay or exit node</i>. It's only used to provide onion addresses so that this gives you or the viewers of your sites some choice about how they access the information. It also allows you to subscribe to and read RSS feeds privately.

 Github is paradoxically a centralized, closed and proprietary system which happens to mostly host free and open source projects. Up until now it has been relatively benign, but at some point in the name of "growth" it will likely start becoming more evil, or just become like SourceForge - which was also once much loved by FOSS developers, but turned into a den of malvertizing.

 Probably you need to add the site to the NoScript whitelist. Typically click/press on the noscript icon (or select from the menu on mobile) then select <i>whitelist</i> and add the site URL. You may also need to disable HTTPS Everywhere when using onion addresses, which don't use https.

 It was originally designed to run on the Beaglebone Black, but that should be regarded as the most minimal system, because it's single core and has by today's standards a small amount of memory. Obviously the more powerful the hardware is the faster things like web pages (blog, social networking, etc) will be served but the more electricity such a system will require if you're running it 24/7. A good compromise between performance and energy consumption is something like an old netbook. The battery of an old netbook or laptop even gives you <a href="https://en.wikipedia.org/wiki/Uninterruptible_power_supply">UPS capability</a> to keep the system going during brief power outages or cable re-arrangements, and that means using full disk encryption on the server also becomes more practical.

 Yes. Freedombone can support a small number of users, for a "<i>friends and family</i>" type of home installation. This gives them access to an email account, XMPP, SIP phone and the blog (depending on whether the variant which you installed includes those).

 On mobile there are various options. The apps which are likely to be most secure are ones which have end-to-end encryption enabled by default and which can also be onion routed via Orbot. End-to-end encryption secures the content of the message and onion routing obscures the metadata, making it hard for a passive adversary to know who is communicating with who.

 If you're making profits out of the logs by running large server warehouses and then data mining what users click on - as is the business model of well known internet companies - then logging everything makes total sense. However, if you're running a home server then logging really only makes sense if you're trying to diagnose some specific problem with the system, and outside of that context logging everything becomes more of a liability than an asset.

 Normally certificates will be automatically renewed once per month, so you don't need to be concerned about it. If anything goes wrong with the automatic renewal then you should receive a warning email.

 Most likely it's because Let's Encrypt doesn't support your particular domain or subdomain. Currently free subdomains tend not to work. You'll need to buy a domain name, link it to your dynamic DNS account and then do:

-Almost everywhere on the web you will read that self-signed certificates are worthless. They bring up <i>scary-scary looking</i> browser warnings and gurus will advise you not to use them. Self-signed certificates are quite useful though. What the scary warnings mean - and it would be good if they explained this more clearly - is that you have an encrypted connection established but there is <i>no certainty about who that connection is with</i>. They probably will protect the content of your communications from passive bulk interception - such as the tapping of under-sea cables.
938
-</p>
939
-
940
-<p>
941
-The current strategy on this system is to typically create self-signed certificates during the initial installation but also to have the ability to easily convert those to LetsEncrypt certificates via the security settings on the administrator control panel.
942

943

944
-<p>
945
-You might say, <i>"but surely LetsEncrypt is a single point of failure!"</i>, and you'd be right. Maybe at some point in future LetsEncrypt is no longer a thing, or no longer considered sufficiently secure. That's why building in total dependence upon one organisation is a bad idea, and it's still possible to have self-signed certs as a fallback option.

 Welcome to the world of email. Email is really the archetypal decentralized service, developed during the early days of the internet. In principle anyone can run an email server, and that's exactly what you're doing with Freedombone. Email is very useful, but it has a big problem, and that's that the protocols are totally insecure. That made it easy for spammers to do their thing, and in response highly elaborate spam filtering and blocking systems were developed. Chances are that your emails are being blocked in this way. Sometimes the blocking is so indisciminate that entire countries are excluded. What can you do about it? Unless you control the block list at the receiving end you may not be able to do much unless you can find an email proxy server which is trusted by the receiving server.

 If you can find some details for an obfs4 Tor bridge (its IP address, port number and key or nickname) then you can set up the system to use it to connect to the Tor network. Unlike relay nodes the IP addresses for bridges are not public information and so can't be easily known and added to block lists by authoritarian regimes or over-zealous ISPs.
