Security providers

The Security Provider allows for encrypting the data source content. To access the security provider, navigate to Administration – Security Provider.

This feature requires an Advanced Data Source.

Regardless of the selected security provider, passwords stored in data sources are ALWAYS encrypted using AES 256 bit encryption.

When configuring a Certificate Security Provider in a published app environment (Citrix, RemoteApp, XenApp) as a Security Provider, the user who will run Remote Desktop Manager in the RemoteApp environment (Citrix) will require a Read permission on the certificate.

If the Read permission is not correctly set, Remote Desktop Manager will generate the CryptographicException - Keyset does not exist error dialog. Follow Certificate Security Provider in a Published app Environment to resolve the issue.

By using a security provider, you ensure that nobody can read entries configuration data, even when people have a direct access to the database(s) or a backup. Shared data sources should always be secured with a security provider.

Prior to applying a new or changing an existing security provider, make sure that every users are disconnected from the data source. If you are changing an existing Shared Passphrase or Certificate, please note that users will get back access to the data source when they enter the new Shared Passphrase or Certificate on their computer.


Please note that changing a security provider on a data source with a great number of entries is a lengthy operation.

Applying a new security provider does process the whole database, therefore we advise you to create a backup prior to this operation.

  1. Go to AdministrationSecurity Provider in the ribbon of Remote Desktop Manager.
  2. Click on Change Security Settings to change the security provider.

  3. Select a security type from the drop-down list.

Default This is the default security mode. The XML is not encrypted by default. Please note that the passwords are always encrypted.
Shared passphrase (V2) The security provider encrypts the whole XML using AES with a passphrase mixed to a private key. The passphrase will be asked once on each machine.Provider.
Shared passphrase (V3) The security provider encrypts the whole XML with a passphrase. The passphrase will be asked one on each machine.
Certificate Set up a Certificate for the Security Provider. Require elevated privileges.
Certificate (V2) The security provider encrypts the whole XML using the private key of a certificate.
Keyfile The security provider encrypts the whole XML using a keyfile provided by you.

Shared Passphrase

If the passphrase is lost, nothing that can be done to recover the data. When using a passphrase, always copy it to a secure location.

Entries configuration data is encrypted using a mix of a key stored in Remote Desktop Manager and the passphrase you have entered.

The passphrase is required only when configuring the data source. A policy can be enabled to always prompt for the passphrase when connecting to the data source.

When configuring a security provider with a shared passphrase, you have the choice of whether or not you wish to save it in the registry. Remote Desktop Manager will try first to save it on the LOCAL_MACHINE, if unable it will save it in the CURRENT_USER instead.

  • HKEY_CURRENT_USER\SOFTWARE\RemoteDesktopManager.shk
  • HKEY_LOCAL_MACHINE\SOFTWARE\RemoteDesktopManager.shk

If the option is not enabled, then the passphrase is saved locally at the following location:

  • %LOCALAPPDATA%\Devolutions\RemoteDesktopManager.shk

In a Terminal Services environment, it should be saved at this location:

  • %APPDATA%\Devolutions\RemoteDesktopManager.shk

In a portable installation of Remote Desktop Manager, the passphrase will be saved at the same location as the portable Remote Desktop Manager instance.


When choosing Certificate as Security Provider, entries configuration data is encrypted using a mix of a key stored in Remote Desktop Manager and the private key contained in the certificate.
