How to use "Opera VPN" with any browser/app which supports proxy

VPN

I hope some people may find this useful.

  1. Download reverse-engineered “Opera VPN” client: https://github.com/Snawoot/opera-proxy/
  2. Run it.
  3. Set up your app to use proxy on address 127.0.0.1 and port 18080.
  4. Done.

Nice. Would be better if there’s a browser extension version of it.

As safe as the original service. If precompiled binaries are concern, it is easy to build it yourself from the source.

I’m pretty sure Chrome/Firefox extension API won’t allow tricky TLS handling required for “Opera VPN” proxies. All you can do with extensions is to specify which HTTPS proxy to use and somehow pass credentials to use with it.

SurfEasy proxies used by Opera have no DNS names bound to it, so hypothetical extension won’t be able to specify proxy host for browser by its name. On the other hand, lack of domain in proxy specification will give no information to browser against which domain name it should validate server TLS certificate.

opera-proxy implements custom connection handling which dials proxy hosts by their IP addresses returned by API and validates their server TLS certificates by expected domain name. Extenstions API provide no ways to implement this, and original Opera VPN implementation baked into native code.

However, for your convenience and/or selective per-site routing you should try SwitchyOmega extension in conjunction with opera-proxy.

I was more concerned with the original service, as I read somewhere that China bought Opera several years ago. I’m not sure I trust software originating in China.

Well, there should at least an API for changing the proxy location just like Tor’s Control Port or the WebUI of the old Toonel proxy. Otherwise, we have to use multiple instances of the application configured with different port number, so that we could choose the proxy location by changing the browser’s proxy setting. That works, but it’s not resource efficient.

Can’t say for sure. Speaking of software, if it was bought it is originated from wherever Opera originated.

Regarding overall influence and jurisdiction, everything in the world falls into somebody influence. I guess wise choice is to pick one having least interest in you.

I agree, that may be useful.
