With all the nastiness going on with spam harvesters, hackers, and politicians, I figured it was about time to start being a bit more careful with my email. Anybody who gets email from me, should find a digital signature certifying that it, in fact, comes from me. The certifying authority may not be in your ‘trusted store’ because I’m certifying my own sigs via my personal domain (durandus.com). Furthermore I’ve set up the necessary tools for establishing digital signatures for all the people at work. I don’t expect most people will use them, but it’s there if they want it.
I’ve set up encryption as well and over the next year, I’ll be asking those people I correspond with regularly to set up a digital signature and encryption keys. It’s not that I’m planning anything nefarious, but I’m getting tired of anybody with a packet sniffer and a federal employee ID figuring that it’s ok to screen my email for content just because they can.
Consider getting your own digital signature — even if you don’t encrypt, yet. You can get an email certificate from thawte. It looks like a pretty good deal (free) and doesn’t require anything more than having an email address.
