Troubleshooting encryption
--------------------------
Problems when downloading or decrypting files
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
In some rare cases it can happen that encrypted files cannot be downloaded
and return a "500 Internal Server Error". If the Nextcloud log contains an error about
"Bad Signature", then the following command can be used to repair affected files:
| ``occ encryption:fix-encrypted-version userId --path=/path/to/broken/file.txt``
Replace "userId" and the path accordingly.
The command will do a test decryption for all files and automatically repair the ones with a signature error.
