Decryption Issue

ℹ️ Support
1

Nextcloud version (eg, 12.0.2): 14
Operating system and version (eg, Ubuntu 17.04): 18.04
Apache or nginx version (eg, Apache 2.4.25): nginx 1.14.0
PHP version (eg, 7.1): 7.2

The issue you are facing:

Files were randomly encrypted and can’t seem to decrypt them

Is this the first time you’ve seen this error? (Y/N): Y

Steps to replicate it:

  1. Do a full installation of NextCloud
  2. Upload/transfer files over to a user
  3. Try to open one of the files

The output of your Nextcloud log in Admin > Logging:

The output of your config.php file in /path/to/nextcloud (make sure you remove any identifiable information!):

<?php
$CONFIG = array (
  'instanceid' => '',
  'passwordsalt' => '',
  'secret' => '',
  'trusted_domains' =>
  array (
    0 => '192.168.1.253',
    1 => '',
    2 => '',
  ),
  'datadirectory' => '/var/www/nextcloud/data',
  'dbtype' => 'pgsql',
  'version' => '14.0.3.0',
  'overwrite.cli.url' => 'http://192.168.1.252/',
  'dbname' => '',
  'dbhost' => '',
  'dbport' => '',
  'dbtableprefix' => 'oc_',
  'dbuser' => '',
  'dbpassword' => '',
  'installed' => true,
  'memcache.local' => '\\OC\\Memcache\\APCu',
  'maintenance' => false,
);

I’m just curious if there is anyway to retrieve or use my data now that it’s been encrypted. It seems to have used the default encryption which appears cannot be decrypted however. The files were transferred from another install (they were not encrypted at that time), however I do not have access to that install anymore.
