In my dev org I have enabled platform shield, created tenant secrete key and enabled encryption for attachments and files. I can see fields are getting encrypted properly but uploaded attachments are not. Is there anything more that needs to be done in order to encrypt attachments. Testing way:
Took one xml attached to one of the record where one of the field is already marked for encryption(Though this is not required.) Now downloaded the attached attachment and I am able to see the completed data. I was assuming the data should have been encrypted but it is not. Is there something which I am missing? Any pointers would be very helpful.
