Freebie certs
 

The best things in life are FREE!!!! Did you know you can get free X.509 certs signed by Thawte (pronounced "thought") for your e-mail client? Pretty shweet deal, if you ask me. Sure beats forcing all your friends to install PGP/GPG so that you can send them encrypted/signed e-mails... ;) Check it out here.

Oh, BTW, did you know Netscape 6 (and Mozilla) do not support S/MIME? Does that blow chunks or what?

this is cool but only if you use windoze. I was trying (asking people how to do it) to implement thawte certificates in my webmail server, but no luck

I don't think you can use those certs in linux.

With an e-mail client that supports S/MIME (i.e. Netscape Messenger 4.x) you can.

well it's worth trying, but I experienced that some users won't be able to open mail with digital signature. Not sure what system are they using

I have one of those I got last year for an address I no longer use (rverland@optusnet.com.au) I didn't even bother adding it to my e-mail proggy!

Well, I got a PGP cert signed by them, when they were still offering PGP signatures... It doesn't expire... Hehehehehe. Now I have one of the most trusted PGP keys out there... ;)
