I added a new post on encrypting email with S/MIME to my series on digital privacy at the Montgomery County Civil Rights Coalition. It reminded me of the difficultry in striking a balance between providing enough information to be useful and accurate but not so much as to discourage or confuse, particularly since the series is aimed at sophisticated people who are nevertheless complete novices when it comes to encryption. Of course, not being a cryptanalyst, computer programmer, or mathematician myself, I also try to keep within the bounds of my own limited, practical knowledge.
