Android App - Set Up Encryption fails

[Wizlonex]

Actual behaviour

Fails to setup encryption option on android app.

Expected behaviour

N/A

Steps to reproduce

1. Select folder to encrypt.
2. Tap menu.
3. Select "Set as encrypted".
4. Click folder.
   --> "Note your encryption passphrase...".
5. Click "Set Up Encryption".
   --> Error message "Error. Storing keys was unsuccessful, please try it again!".
6. Click close.
   --> (If you try to enter the "encrypted" folder, the process (and error) repeats from step 4).

If I try to access the encrypted folder via the web portal, it errors (probably expected behavior?).

Nothing useful seen in server log because it does not record the client-side error (but it does record the accessing encrypted folder failure, which is normal I think?). I am happy to try to provide additional info.

If I try to send app logs, the app crashes ('Nextcloud has stopped'). But even so, there are no app log entries associated with the encryption set-up failure anyway.

@schiessle strange that there is nothing on server log, or?
I assumed that the CSR is not valid, maybe related to #1859

I'm experiencing the same behaviour.

Error     end_to_end_encryption     2018-01-23T17:15:18-0500
Can't create public key: could not sign the CSR, please make sure to submit a valid CSR

Error     PHP     2018-01-23T17:15:18-0500
openssl_csr_sign(): cannot get CSR from parameter 1 at /apps2/end_to_end_encryption/lib/SignatureHandler.php#60

Not sure if relevant, but I'm using this Docker image: https://github.com/hoellen/dockerfiles/blob/master/nextcloud/Dockerfile.13.0

Could this be a libressl issue? (I'm really not sure about cross compatibility between open and libre.)

EDIT: This could be a coincidence, but @yb171, who commented on #1859, and @Wizlonex are both using Pixel 2 XL and I'm using a Pixel XL.

Having a similar issue on my Pixel 2 XL with the latest version of the Nextcloud app from Google Play. See #2134

[tobiasKaminsky]

Please try 3.0.1 as this is most probably related to #2134 as @ardevd said.
If not, please comment here and re-open.

Not fixed as of 3.0.1 for me. Still getting the same errors in the logs:

Error | end_to_end_encryption | Can't create public key: could not sign the CSR, please make sure to submit a valid CSR | 2018-02-23T10:33:19-0500

Edit: Reading through #2134. Will try deleting keys via curl.
