10.3: S/MIME encryption and Mail.app
Authored by: macthemes on Feb 09, '04 12:01:40AM

Does anyone know how to move a cert and keys from a Windows machine to my Mac? I tried exporting them and importing them on the mac side and got my cert and my private key, but no public key. Mail doesn't seem to want to sign anything without the public key. Is there anyway to generate the public key from the cert? I know it's in there, I just don't know what format Keychain Access wants it in.

Keychain access needs a lot of work, and way more documentation ;-)

10.3: S/MIME encryption and Mail.app
Authored by: legacyb4 on Feb 12, '04 12:22:40AM

I did the following on my PC (Windows 2000), in order of menus:

- Internet Explorer
- Internet Options/Content/Certificates
- Select Thawte Freemail certificate
- Export
- Export the private key
- Select PKCS #12 (.pfx)
- Enabled strong protection (not really needed, I think)
- Type password (if strong protected)
- Save somewhere and mail to yourself on your Mac
- Double-click downloaded file and it should add itself to the Keychain

Voila, done.

10.3: S/MIME encryption and Mail.app

I did the same, but with no luck. I'm currently hypothesizing that Mail requires your cert to have the altSubjectName extension (which Thawte certs have) for Mail to work properly. My corporate cert doesn't have that extension, hence I'm having problems. There's quite a good writeup on this here on Macintouch
