Store Data of the Extension

Quite often an extension needs a storage to keep its data - for example,
user settings or secret keys. As a developer, you have a variety of ways
to store data, like files or databases. Additionally, Plesk provides the
mechanism of Key-Value Storage to simplify storing and
accessing data.

Encrypting Data

If you need to store arbitrary data in encrypted form, use the following
methods of the
pm_Crypt
class:

• encrypt()
  to encrypt, and
• decrypt()
  to decrypt data.

The following code encrypts the value from your variable:

$password = "secret password";
$encryptedPassword = pm_Crypt::encrypt($password);
// store $encryptedPassword to your own storage
