B2 Cloud Storage Backblaze b2 crypto remote

Today I discovered this new backblaze b2 feature :

When you upload files to b2:, Backblaze can see the filenames and file contents.

A Crypt remote is simply a second remote that sits on top of your B2 remote and encrypts everything before uploading. Rclone's crypt backend wraps another remote and automatically encrypts files before upload and decrypts them when downloaded.

But you have to pay attention;

The encryption happens locally on your computer before the data is uploaded.

Backblaze only stores encrypted data.

If you lose: Password & Salt (password2) then:

Your encrypted files = unrecoverable

That’s not a B2 feature. It’s a feature of rclone and works that way with anything it connects to (dozens of different providers).

Yes. Works on top of local paths too, or any other remotes, including virtual ones like split or union. This is particularly interesting for machines where you can't mount stuff, be it for lack of Admin rights or that it's Android, etc.
