You can implement the encryption filter to enable secure file downloads by encrypting the content files before they are downloaded from Windchill. This customization restricts access, preventing unauthorized users from reading or accessing the contents of the downloaded files. The encryption filter checks that the HTTP request is for the content file download and that it is in the expected format, and then encrypts the content file.

Out-of-the-box, the encryption filter is not shipped with Windchill. You can configure and deploy it in your environment as per your business requirement. The servlet filter supports all encryption strategies and is applicable for all kinds of contents downloaded from Windchill.
