How to get/set up EPMA Planning/Essbase maxl encryption in Linux

HI Gurus,

Need your urgent help !!!!!!

My current encryption Keys (Public and Private keys along with maxl encrypted username and password for the admin) were not working since the system upgradation from windows to Linux around an year back these jobs were did not run and we need to bring these setup back to normal.

Now, unfortunately, we do not have the above Admin username and password details which was used for the current encryption process and bcz of that the all the batch jobs that were set it up based on this encryption keys were not running now.

Considering the above situation I have, would you please help me to check where I can get the admin "username" and "password" details that were used part of the initial encryption setup and the default location of these encryption path and where we can usually find out (In my instance have Essbase server or Foundation server Linux boxes) and if I never can get the username and password credentials based on the current encryption keys , then please help how I can get a workaround and setup the new keys atleast using my individual username and password in Linux so
