When you receive a Kinar message with a tamper-proof message (or file), the secure information is wrapped in attachments with .knp extension.
Just double-click on the attachment (from within the message or after saving it in a folder). Kinar viewer will be launched and if the attachment
is in tamper-proof form, it will decrypt and display the attachment. Note that the viewer will not allow you to copy information from
a tamper-proof file nor will it allow you to print it.
