  1. Hello! On server side, we use OpenVPN 2.5 to support ChaCha20 on the Data Channel, so any server with OpenVPN 2.5 will be marked as "Experimental", to make clear that the OpenVPN running in it is a beta version. As soon as OpenVPN 2.5 stable is released, all the servers will be upgraded to support ChaCha20 on the Data Channel without the "Experimental" warning. Our next, imminent step is releasing Eddie Android edition with OpenVPN 3 supporting ChaCha20-Poly1305 to allow immediate testing from those devices based on Android that need ChaCha20 most, for performance and load reasons (such as any Android tablet, smart phone, Amazon Fire TV and any other Android based mediacenter using a CPU that does not support AES-NI). Kind regards
  2. Hello! In addition to what HannaForest wrote, use end-to-end encryption in any case. Kind regards
  3. @prebrov Please see also here to avoid conflicts: https://airvpn.org/forums/topic/26209-how-to-manage-client-certificatekey-pairs/ Kind regards
  4. Hello! We see now that the web site you mention also blocks some Tor exit-nodes we tested. This fact alone puts an end to your insinuations: go trolling somewhere else. Kind regards
  5. A user can be sure that we do not infringe end-to-end connectivity principle and draw his/her own conclusions. It makes a world of difference and raises various questions, for example why does a service want to know your real IP address? Kind regards
  6. Hello! The final web server and/or firewall on the final service machine blocking our VPN servers exit-IP addresses on ports 80 and 443 explains your observations. Kind regards
  7. Hello! We do not block any outbound port except 25. We are forced to do it to mitigate mail spamming. Outbound ports 80 and 443, as well as any other port except 25, are not blocked for any destination. Kind regards
  8. Hello! We are very glad to inform you that our OpenVPN 3 development is progressing swiftly. Today we implemented directive ncp-disable which was still unsupported in OpenVPN 3. https://github.com/AirVPN/openvpn3 The directive is instrumental to allow clients Data Channel cipher free selection between those available on server, when ncp-ciphers is declared on server side, and keep at the same time total backward compatibility. Since when we implemented ChaCha20-Poly1305 https://airvpn.org/forums/topic/43850-openvpn-3-development/ on OpenVPN 3 Data Channel, "ncp-disable" has become a priority to provide servers and clients with maximum flexibility. We can therefore leave total freedom to clients to pick between AES-GCM, AES-CBC and ChaCha20 while preserving full backward compatibility. Clients with AES-NI supporting processors will prefer AES, while clients running on CPUs without AES-NI, for example most ARM CPUs, will of course tend to prefer ChaCha20. We are working hard to bring you first and foremost a new Eddie Android edition beta version to let you test ChaCha20-Poly1305 on your Android devices as soon as possible. All internal tests both with ChaCha20 and ncp-disable have been fully successful so far. Fingers crossed, maybe you will see a beta release as early as next week. https://github.com/AirVPN/openvpn3 Changelog 3.3 AirVPN - Release date: 13 July 2019 by ProMIND - [ProMIND] [2019/06/02] Forked master openvpn3 repository 3.2 (qa:d87f5bbc04) - [ProMIND] [2019/06/06] Implemented CHACHA20-POLY1305 cipher for both control and data channels - [ProMIND] {2019/07/10] Implemented ncp-disable profile option Kind regards and datalove AirVPN Staff
  9. Nonsense. The tags were meant to make the review easier and in the subsequent commit they were removed as required. Kind regards
  10. Hello! The problem doesn't occur anymore, but if you still experience the issue, probably Eddie won't open again for a corrupt configuration file. If you use Windows version, download and launch this hotfix . Otherwise, please delete default.xml file (on Linux and Mac it's located in ~/.airvpn/default.xml). At the next run, Eddie will re-create a configuration file with default settings. You will need to enter again your AirVPN credentials.  Kind regards
  11. Yes, we're very glad to confirm that the implementation of ChaCha20-Poly1305 on OpenVPN 3 Data Channel is complete and fully working according to our tests, which have been quite thorough. Schwabe's objections are questionable and never enter into the real argument: look at the previous source code of OpenVPN 3 and the new code by ProMIND. You will see all you need to know. Of course our OpenVPN 3 source code will remain available to the community and we want to underline that the style is compliant to the most up to date Knuth's guidelines on the Art of computer programming, while OpenVPN 3 source code is not. We have doubts to comply to Schwabe's requirements and we need to consider the matter carefully: if higher standards are deemed as a problem, then the real problem lies probably in the low standards, not in the higher ones. We now need an additional commit to OpenVPN 3 (almost ready to be published, already tested successfully) and then we will start to develop and release all the software according to the plans we have published. We are talking about days, stay tuned! Kind regards

  13. Hello! We deeply apologize for the problem that was not caused by Eddie, but by our bootstrap servers. The problem has been resolved. Kind regards
  14. Hello, since 2017 we've been contributing to run about 5-7% of all the worldwide Tor traffic through exit-nodes maintained by Quintex Alliance, please check our mission page. Kind regards
  15. Updated. Please see https://gitlab.com/AirVPN/EddieAndroid/ and feel free to contact us if you have problems to build it. Kind regards
  16. @air521745 We're sorry, the plan to make it available on F-Droid has been dropped. Kind regards
  17. @💩💩💩 Thank you for your feedback! We will consider seriously your suggestions. About point 2, however, that would not be a master password, but something mainly useless. Maybe an option that could meet your needs is simply disabling the Master Password, but that affects security just like your proposal. Letting the user to opt-out from the MP seems the only reasonable way (i.e. the user deliberately and freely renounces to a security feature). About point 7: yes, the app is authorized by Android system. Remember that the Android system option you mention is not strictly meant to prevent any POSSIBLE leak outside a VPN tunnel, but to mitigate them by restricting comms to registered apps only. Also, your ISP sees the IP addresses your system contacts to connect to a VPN, over TLS or not, with Eddie or not. By the way, we don't think that Eddie pings at any time ipleak.net (we will check with ProMind) and when the network is in lock state (by Eddie) the app can't access anything, including ipleak.net. Remember in any case that ipleak.net is controlled by airvpn.org. Connection to it is very important to let the app understand what the best server to connect to can potentially be, as we can't use "ping" in any way to determine round trip times. That's a great feedback, thank you! Kind regards
  18. Hello! On April 2018 we made an important step forward: we began to accept Bitcoin directly, through no intermediaries at all. Today, we're very glad to announce that we are able to accept directly more cryptocurrencies. In alphabetical order: Bitcoin Bitcoin Cash Dash Dogecoin Ethereum Ethereum Classic Litecoin Any intermediary acting as a payment processor is no more required. As we wrote in 2018, we stll feel it as an additional, important step forward in privacy protection. Moreover, cutting out any intermediary is very coherent with cryptocurrencies spirit and unleashes their potential. Kind regards and datalove AirVPN Staff

  20. Thank you! Of course. The idea has been floating around since several years ago https://community.openvpn.net/openvpn/wiki/RoadMap The OpenVPN 3 Core Library is based on a different approach, implementing the OpenVPN protocol as a C++ library. This gives lots of the same possibilities and modularity as this draft tried to resolve. Further, OpenVPN 3 is multi-thread capable and integrates with ASIO for all asynchronous processing and socket handling.
  21. We agree, when AES-NI are supported. Note that some processors do support AES-NI but the system doesn't use them (examples: AES-NI disabled at BIOS level; OpenSSL or other SSL library not properly compiled). Also see https://tools.ietf.org/html/rfc8439#appendix-B (however note that the comparison is made between AES-128-GCM and ChaCha20 but a more correct comparison would be with AES-256-GCM because of the 256 bit key size of ChaCha20). Not only the appendix but also important considerations in the introduction and later. Kind regards
  22. Hello! We're very glad to inform you that AirVPN has begun to actively contribute to OpenVPN 3 development. Our first goal has been adding support for ChaCha20 cipher with Poly1305 as authenticator on OpenVPN 3 Data Channel. ChaCha20 is a stream cipher developed by Daniel J. Bernstein which combines strength and remarkable performance. https://en.wikipedia.org/wiki/Salsa20#ChaCha20_adoption When compared with AES-GCM, ChaCha20 offers significant computational relief to all AES-NI non supporting processors, such as ARM processors. ARM processors, routinely used on very many tablets, smart phones, media centers, smart TVs and routers, will get great benefits from OpenVPN with ChaCha20. Our tests show that CPU load caused by ChaCha20 on recent ARM 64 bit processors is at least 50% less than AES-256-GCM, on equal terms, which translates into dramatic performance boost and longer battery life (if you have ever tested Wireguard on an ARM based device you know what we mean). OpenVPN 3 is a client library. However, OpenVPN 2.5, which is currently in beta testing and includes all the necessary servers features, supports ChaCha20 on the Data Channel. Therefore, making OpenVPN 3 with ChaCha20 available to our users and allowing a real life test will be a matter of days. We will progressively release beta clients for Android, Linux, OpenBSD and FreeBSD, in this order. We are considering a porting to OpenIndiana as well. Internal alpha testing has concluded successfully. We have already pulled a merge request to OpenVPN 3 main branch, to let the whole community take advantages from our code, and let OpenVPN developers merge the new code into the main branch if they wish so. https://github.com/OpenVPN/openvpn3/pull/78 Implementation has been designed, developed and programmed for AirVPN by ProMIND, who is also Eddie Android edition developer. Stay tuned, more will come! UPDATE: https://airvpn.org/forums/topic/44069-openvpn-3-development-by-airvpn/ The above linked topic is now the central thread to discuss anything related to OpenVPN 3 development and testing. Kind regards and datalove AirVPN Staff
  23. Hello, we wish (in our setup, we mean) that stunnel accepts any connection to bypass restrictions, even when it will have certificate replacement and therefore it is subjected to MITM exploits. The integrity and data security layer is ensured by the underlying OpenVPN tunnel. stunnel is not there to add anything to security when you use OpenVPN over SSL, it is there to try to punch a hole in the filters through which OpenVPN can establish its tunnel. Kind regards
  24. @idealist You don't understand. With static IP addresses stored on the servers you map uniquely and permanently an IP address to a user. Once that IP address is discovered (no need to crack the server, as we wrote) the correlation is done because we know which user always has that IP address, even if we don't log traffic, and we would give away the information under a court order. Which is exactly what go558a83nk already explained to you. This is not possible with OpenVPN, as the dynamic IP addresses are never correlated to a user once the session is over, they are lost. So if the attacker asks "who has that IP address?" with OpenVPN in our setup we don't know, while with Wireguard in the current (at the time of writing) stage of development we would know. If now or in the future Wireguard will allow dynamic addresses assignments, so that no address must be stored permanently for any client, the problem is resolved, but at the time we wrote the article it was not. Kind regards
  25. The issue has been already explained: the keys and the internal IP addresses are all on the server, and they are on every and each server. They can be used to correlate specific targets and disclose their identities, while on our current setup that's not possible. It makes a world of difference when you consider threat models in which VPN users are specifically targeted. Maybe you don't understand the importance of this menace because you wrote: which is correct in our setup, but incorrect in Wireguard setup. The attacker CAN get the internal IP address via WebRTC for example and: 1) in our setup he/she does not correlate the internal IP address with the client key 2) in Wireguard setup he/she does Once that's done the attacker may obtain legally (via a court order) the payment data of the user because it can ask us which user is linked to a single IP address (and also the user key for subsequent forensic evidence). Since the VPN IP address is static and unique, we would be of course forced to comply. We wish to underline for the last time that the problem has been acknowledged by developers and we had been told that it would be resolved. Kind regards
