@Softvision-CristinaBadescu , I know what I'm going to ask is very stupid and nothing related to this issue. How is send working on edge without showing the unsupported page ?

[Softvision-CristinaBadescu]

@himanish-star, don't worry, it's not stupid what you're asking. Some months ago, Firefox Send was working in Edge, but something changed and caused this issue. Until this is fixed, it has been decided that the best solution is to display the unsupported browser page.

Ok, I'm finally looking at this. It's going to require we implement PBKDF2 and HKDF APIs in webcrypto-liner. It does look like asmcrypto.js implements the algorithms we need so it's "just" a matter of implementing a webcrypto interface.

This issue is no longer reproducible on Firefox Send dev version, using Microsoft Edge 40.15063.674.0 (HTML version 15.15063).
