File Encryption/Decryption in SAP MII 14/15

Hi guys,

For one of our clients we are uploading particular files(xls.txt,doc,pdf.) through UI from MII.

These files have to be stored on MII application server with encryption.

Similarly, these files while fetching should be decrypted.

Let me know if the same can be done:

1. Any standard MII feature.
2. Using Custom Action Block
3. Third party tools
4. Any other workaround

Request you to let me know your thoughts.

Regards,

Anuj
