  <h1>Encrypting Files<a class="headerlink" href="#encrypting-files" title="Permalink to this headline">¶</a></h1>
  <p>By default, ownCloud provides an Encryption app.  This app enables encryption
  of all files stored in your ownCloud. Once enabled by the administrator, all of
  your files are encrypted automatically.</p>
  <p>Encryption and decryption always occurs on the server side. This enables you to
  continue to use all other apps to view and edit data. However, this method of
  encryption also means that the server administrator can intercept your data.
  Server-side encryption is especially useful if you use external storage. It
  ensures that the external storage provider is not able to read your data.</p>
  <div class="admonition note">
  <p class="first admonition-title">Note</p>
  <p class="last">Once the Encryption app is enabled, your log-in password is required
  to decrypt and access your data. By default, your data will be lost if you
  cannot use your log-in password to retrieve it. If you want to protect yourself
  against password loss, store your log-in password in a secure place or enable
  the recovery-key feature as described below.</p>

  <p>This option is only available if your log-in password, but not your encryption
  password, was changed by your administrator. This can occur if your ownCloud
  provider uses a external user back-end (for example, LDAP) and changed your
  login password using that back-end configuration. In this case, you can set
  your encryption password to your new login password by providing your old and
  new login password. The Encryption app works only if your login password and
  your encryption password are identical.</p>
