PDF to base 64

Is there anything in proccess studio that can helpme transform a PDF file do base 64 format? Or in anyway transfer this PDF file to the oracle database directly?

I Believe you can do it using powershell step.

Thank you.
I tried with powershell step but i got the about_Execution_Policies error.
When i open powershell from windows, it works.
You know how i can give ProcessStudio the access to run the powerShell script?
