As many of you have probably seen, Firefox launched their encrypted file sharing system, However the service is discontinued right now, I’ll share your curated sharing tools which have a client-side encryption feature.You can find a similar service hosted by structures in which we have trust by going to the following sites:
An instance of Send, Encrypt and send files with a link that automatically expires.
Another instance of Send, Encrypt and send files with a link that automatically expires.
Public instances of Lufi
It’s also worth noting that FilePizza is a useful utility if you are frequently having to transfer large files. The application does not set a restriction on the maximum file size, like other file-sharing apps or tools. This gives you a chance to share very large files that one or even multiple recipients can download.
Send up to 50 GB,Free and no registration required,Files stored in Switzerland,Keep your transfers for up to 30 d.
Send files up to 20GB,No sign up required,Unlimited downloads,This feature is only available in SendGB.
It’s a js to en/decrypt files localy but not to send them,so you’ll have to find another way to send them, but they’d be client-side encrypted. The other person would use it as well to decrypt the file,which is to say you can use any cloud storage to share the file.
WeTransfer is the simplest way to send your files around the world. Share large files up to 2GB for free.
At last,You can self host Send,which is all open source.
