MD5sum Checksum Logic in ABAP interface

Hi All..

I am Pavan, ABAP Consultant from Bangalore, India....

How to incorporate MD5sum checksum logic in ABAP interface...???

FYI, MD5sum is a checksum tool available in the web. This tool will generate a unique No' for each flatfile downloaded from SAP via extracts..

When i send the same flat file to my client, they will validate the checksum again.. Once it is validated, then it will be confirmed that data is not tampered... Otherwise, client will reject the file..

This is a mandatory process for my client, since they are working as per SOXa standards... (Sarbanes - Oxley Controls & Process)

Please help me, if any one of you have the information regarding this ..

Thanks in Advance......
