This. It serves no purpose other than to confuse, to send someone who
doesn't use OpenPGP an OpenPGP message. People using X.509 certificates
for e-mail will probably expect S/MIME messages, which while potentially
using RSA just as OpenPGP can use, are distinctly different from OpenPGP

This is phrased wrong. Actually, what many people call OpenPGP keys are
more accurately called OpenPGP certificates. But X.509 certificates are
not OpenPGP certificates in any sense. They both potentially use RSA.
But RSA is an algorithm, giving computation rules for numbers. RSA is
not a data format or standard for message exchange. That would be
OpenPGP or S/MIME, which do not interoperate. And, by the way, don't
even necessarily use RSA at all, it's just a common option.

I hope this makes it more clear to you.



I use the GNU Privacy Guard (GnuPG) in combination with Enigmail.
You can send me encrypted mail if you want some privacy.
My key is available at <>
