conpal LAN Crypt 2Go Reader supports two different installation modes: Current User and All Users.

Installation option: All users.

By default, the installation of conpal LAN Crypt 2Go Reader does not require administrator privileges and can be performed by any user. If the installation is performed by one user, the application will be installed so that it is only available to that user. Other user accounts on the same system will not have access to the installed product.

The administrative installation of conpal LAN Crypt 2Go Reader makes the product available to all users. To do this, you must run Setup in Advanced mode and override the MSIINSTALLPERUSER parameter.

Uninstall conpal LAN Crypt 2Go Reader

conpal LAN Crypt 2Go Reader can be removed from a system at any time. Uninstallation follows the standard software removal procedures for each platform.


  • After uninstalling conpal LAN Crypt 2Go Reader, encrypted files on the computer can no longer be decrypted. Uninstalling conpal LAN Crypt 2Go Reader does not uninstall any other product from conpal LAN Crypt.

conpal Cloud Support

Using the conpal Cloud allows users to securely store their keys in the cloud. This happens automatically and provides access to the keyring from all of the user’s devices, across all platforms supported by conpal LAN Crypt 2Go Reader.

Changes to the keyring, whether it’s adding, deleting, or renaming a key, are automatically synchronized with the other devices. This ensures that the user always has access to the most up-to-date keys, regardless of which device they are working on.

Signing In and Out

To sign in, tap the Account icon in the top right corner of the conpal LAN Crypt 2Go Reader application and select Sign In:

If you have password-based keys in your keyring, the user will be asked for permission to upload the keys to the conpal Cloud. Permission to upload existing keys is mandatory. If a user does not want existing keys to be uploaded, the keys must be deleted before signing in to the conpal Cloud. Note that passwords for password-based keys are not uploaded to the conpal Cloud, so the Show Password option for keys stored in the conpal Cloud is not available.

After clicking on Sign In, the user’s default browser opens, asking for the login data for the conpal Cloud. After entering the login data, a success message is displayed in the browser. This confirms that the login process has been successfully completed and the user now has access to his keys stored in the conpal Cloud.

To sign out, follow the same procedure, but select Sign Out instead of Sign In. After signing out, you will no longer have access to the keys stored in the conpal Cloud until you sign in again. This serves as an additional level of security to prevent unauthorized access to your keys.

Decrypting password protected files

Using the graphical user interface

When opening the app by selecting the conpal LAN Crypt 2Go Reader program icon, the decryption dialog will appear. Use the Select… button to select the file to decrypt or drag in the desired file.

When decrypting a file that has been password-encrypted by one of the LAN Crypt products, the system first checks whether the required key is already stored. If this is the case, it is automatically used for decryption. If the required key is not yet available, the key password must be entered to successfully decrypt the file. A key is derived from the entered password and saved, so it can be used for further encryption and decryption.


  • When decrypting a file, conpal LAN Crypt 2Go Reader creates an unencrypted copy of the file. It also restores the original file extension of the file by removing the .pcrypt extension.

Using the context menu

conpal LAN Crypt 2Go Reader adds its own commands to the context menu of files. These are displayed when you right-click on a file. Files can be decrypted directly from the context menu.


Using drag-and-drop

Simply drag the file you want to encrypt or decrypt onto the program icon of conpal LAN Crypt 2Go Reader.


View and edit encrypted files

Files can also be edited directly without manual decryption. In this case, the encrypted file is automatically decrypted when opened and then re-encrypted with the corresponding password after editing. The prerequisite for this is that the required key has already been saved or is entered correctly on request.

The respective standard program is used to edit the file (e.g. original .docx files are opened with Microsoft Office by default).


  • If an encrypted file is read-only, the temporarily decrypted file is also read-only. This usually results in the respective default program preventing changes to the file.

  • To create a decrypted version of a .pcrypt file, you can either use Save as within the respective editing program or open conpal LAN Crypt 2Go, select an encrypted file and tap the Decrypt button.
