Important information

• The DXL Encryption tool is for DOORS 8.x on Windows platforms



• Use the DXL Encryption Tool to encrypt DXL files you have written. The tool can be used to encrypt DOORS 8.0 or 8.1 DXL files. The tool is a one way encryption tool, and does not decrypt files. Customers are advised to keep the original DXL that they encrypt in a safe place.



• Files that have been encrypted by the tool are decrypted by the DOORS client, which can run any DXL files that have been encrypted by the tool. Encrypted DXL cannot be loaded and run from the DXL Interaction window, it must be #included.



• It is not possible to execute encrypted DXL from a menu item. If this is required, a wrapping un-encrypted DXL file must be used.



• The encryption tool is not unicode enabled. This means that all paths and filenames must be ASCII.



• The encryption tool uses similar security to the encrypted DXL that is shipped with DOORS.

Installation instructions

To install the DXL Encryption Tool:

1. Double-click DOORS_DXL_encrypt.exe.



2. On the Welcome screen click Install. The file is installed to the bin directory of your DOORS installation.
   
   • If both DOORS 8.0 and DOORS 8.1 are installed, it is installed in the bin directory of the 8.1 installation.
   
   
   
   • If you don’t have DOORS 8.0 or 8.1 installed on your machine, then the installation fails.

Running the Encryption Tool

To encrypt a DXL file:

1. The first three bytes of the DXL file that you want to encrypt must be:

   //<

   If these characters are missing DOORS will not be able to execute the DXL.

2. Open a command prompt.
3. Type:

   end_user_protdxl.exe "dxl to be encrypted" > "output encrypted dxl"

   Where "dxl to be encrypted" is the relative path and name of the DXL file you want to encrypt and "output encrypted dxl" is the relative path and name for the output.
