Zip and CSV file to IDOC

Hi,

I have a requirement is that there is a zip path and it has some csv files, XI need to pick up the files from this path using File sender communication channel and convert into it IDoc.

PI is able to pick up files but all input values are in encrypted format due to this getting mapping error.

I have tried all option from forum,can some one please provide inputs on the same.

Cheers,
