Files uploaded directly to SharePoint are
decrypted when FRP is installed.
If the FRP keys are unloaded, SharePoint complains about the file name because FRP changes the file name.
If you exclude
iexplore.exe or
firefox.exe from access to the FRP keys,
the document can be uploaded to SharePoint and retain the encryption. But, the extension is modified. When the file is later downloaded to the client, the following problem occurs with the extension:
- SharePoint does not recognize the modified file extension.
- When trying to download using the browser Save As option, the following is added to the file extension: <sample.doc%>EE%B3%30.txt
