UDESEncrypt Errors when using the JAVA engine (NW IDM 7.0)

Question

Folks,
I'm seeing an error when I use the uDESEncrypt function with the Java Engine in NW IDM SP2 Patch 3.
The error I am getting is:
runFunctionsInString($FUNCTION.encrPWD()$$) got exception
org.mozilla.javascript.EvaluatorException: uDESEncrypt: Key should be exactly 24 bytes long.
The code calling it is:
// Main function: encrPWD
function encrPWD(Par){
     //Example calling DSE internal function
     //UserFunc.uStop("Terminated by user");
     key = "C:\Program Files\SAP\IdM\Workflow\configs\KEY\keys.ini";
     OutString = UserFunc.uDESEncrypt(key, Par);
     return OutString;
I have also seen this error when using Patch 4.
Interestingly enough, the error does not occur when using the Windows Engine.  Anyone else seeing this?
Thanks,
Matt

Hi Matthew,
Try to replace the '\' with '
key = "C:
Program Files
SAP
IdM
Workflow
configs
KEY
keys.ini";
Alternative approaches,
1) setting key empty and it will look into %DSE_HOME%\KEY\key.ini
  which should be C:\Program Files\SAP\IdM\Identity Center\Key\key.ini on default installation path.
2) or setting the key to something like = 6D5A2AF59B1CDD7F9592484F178331C891537A3F9B91D362
   a 24 byte key...
Also when using DES you should ensure that in Identity Center underneath Options/General
you have encryption algorithm set to 3DES.
Normally if you intend to use this for password provisioning in IC you would also
on the identity store (for instance 'Enterprise people') underneath 'password policy' check
of for 'enable password provisioning.'
By doing so the MX_ENCRYPTED_PASSWORD with be set when operating through
workflow (3DES encryption version of the MX_PASSWORD) which allows you to obtain password
when provisioning to other target systems...
