I don't know here Mozilla got their inspiration, but Send looks pretty similar to our E2E encrypted file sharing app Whisply: https://whisp.ly

PS: Whisply even has more features and a detailed description how its encryption works: https://whisp.ly/static/whisplyTechnicalOverview_20151201.pd...

There's many such tools available, RiseUp runs one called Up1. See https://share.riseup.net/

It's quite nice, has integrated image and video viewers as well as a pastebin all end-to-end encrypted.

Up1 looks nice, but is internally using SJCL which is slow and does not support bigger files ("This is not a problem with sub-10MB images"). Send - and Whisply - are built on the new WebCrypto APIs which are faster and allow bigger files, up to 1 GB in both cases.

If you're looking for an alternative, you might want to try our app Boxcryptor: https://www.boxcryptor

Hi Chris, the very first versions of Boxcryptor for Windows some years ago also used Dokan. Our experiences have been really bad and as the user base grew so did the number BSOD reports caused by Dokan (v0.6 back then). We are now using the commercial driver CBFS since 3+ years and are really happy with it. Hint: As development at Dokan has picked up again with Dokany, I don't know anything about its current stability.

You should be able to use it with any mobile encryption app which is compatible to EncFS, e.g. Boxcryptor Classic on Android and iOS (more info: https://www.boxcryptor.com/en/classic)
