NewTmpFile is used for what you are describing. Actually it is not for
temporary storage, but for atomic file writing/renaming.
But temporary file for nncp-exec/"nncp-file -" holds really temporary
data, used for encrypted packet preparation.

>Just to confirm -- everything written to /tmp is encrypted, right?

Everything that written to the file in $TMPDIR, if more precisely.
Yes, it is encrypted with the random ephemeral key, exactly to be able
to place it anywhere you wish without fear.
