Re: smime.el: security concerns?

[Richard S. <rm...@gn...>]

      - `call-process' / `call-process-region' (temporary files in /tmp/?)
      - environment variable(s) for password passing
      - documentation encourages use of un-passworded .pem
      - password caching via elisp instead of external agent
	- personally avoid, even for tramp + SSH
      - the very manual .pem key/crt setup was tricky

We have eliminated the same problems in the rest of Emacs; shouldn't
we fix smime.el to get rid if them too?
