MD5 encryption in RTF template

Hello Peeps,

In BI Report output using RTF template, need to to include a URL string which is formed using multiple flex field values and need to encrypt that particular URL using MD5 encryption

I want to encrypt particular field formed using concatenated flex fields using MD5 in RTF template. Below given an example

    Unencrypted URL: http://www.skidmore.edu/uplod.php?d={ qrystring } where qrystring = applicID + jobID+ ref email address

This will look like: www.skidmore.edu/upload.php?d=applic_id=36890&job_id=1000786&ref_email=harris.test2@xyz.com

    Encrypted URL: http://www.skidmore.edu/uplod.php?d=JDGjsghfdghFDGHSFDHGFdsjfdhfggfdsfgjsdagjkfgajdafdsajgjadsfajsfg
