hashlink VS Signal-Desktop

What's missing is a way to pin web apps so that you always get the previous version (and can opt in to subsequent versions after checking their hash from a trusted source).

There is a clever way of doing this, using a bookmarklet, a dataURI, and SRI, but the UX isn't great.[0] If something like Hashlinks[1] were supported by browsers, though, this could work quite nicely.

> What about websites though?

It is possible for a web page to specify the expected hash of a script file, which the browser will enforce. This is called SRI (Subresource Integrity).[0]

Of course that still leaves the bootstrapping problem of how the page itself can be guaranteed to have a specific hash, but fortunately there is a clever hack that can be done with bookmarklets[1], or the page can just be saved and loaded/served locally.

While that works technically, the UX isn't great because the address bar won't show the domain of the remote server (although browsers seem to be hiding the address bar from the user more and more). A better solution would be for browsers to support Hashlinks[2], which would allow a bookmark to point to a remote page with fixed contents.

It does, see [0]. Fun fact: Signal desktop, which uses Electron under the hood, is running without sandbox on Linux [1][2].

There was a issue opened on GitHub a while back apparently but that was closed due to inactivity. What you might want to do is either open a new issue directly in GitHub (provide as much information as possible and include debug logs) or just send them a support ticket via the support form (and include debug logs).

Desktop will have it https://github.com/signalapp/Signal-Desktop/commit/9bfbee464bc307a9133ccf43042987343722afe9

Issues have been ongoing for the past couple weeks. It's not clear if this is the client or backend. Dual stack works again with v6.20.2, but IPv6-only with NAT64 still doesn't. Actively being worked on, and hopefully some good learnings. Issue link thread: https://github.com/signalapp/Signal-Desktop/issues/6439

Alive again with 6.20.2 on Windows dual stack. Directly downloaded from https://signal.org/download/
