documentation Add information about E2E encryption

The client-side encryption is not really documented, there is nothing about the current 2.5 desktop client. Without documentation it is hard to answer them without trying each option yourself (still it would be hard to say if this is default behavior, some mis-understanding function or a bug). In the forum, there are already questions piling up: https://help.nextcloud.com/tags/e2e

There is currently the technical part in https://github.com/nextcloud/end_to_end_encryption_rfc/blob/master/RFC.md

On android side we do have some intro while setting up E2E, but no dedicated help/info. As with other parts I would rather go with a better UI/UX than having a real documentation. After all E2E should work seamless without knowing technical parts. If people cannot set it up properly, we failed at UX.

But in general, please note that there are currently know bugs, especially in Desktop.

The README for the E2EE repository was (significantly) expanded recently. Even added basic troubleshooting steps, etc. :-)

https://github.com/nextcloud/end_to_end_encryption/blob/master/README.md

I suggest directing people there for now.
