Try :X option in vim.



Code:
:X      Prompt for an encryption key.  The typing is done without showing the
        actual text, so that someone looking at the display won't see it.

It is more or less impossible to prevent a user one a remote system from opening a file you sent him.
Thats why encryption is used. Opening a file will not help an unauthorized user in any way as he is not able to interpret its content.
