OK, everyone can have a bad day, right?
Yesterday, I had one, finding a “new” old spotlight feature in the Context menu of Mail and completely misunderstanding what was happening with digital signatures in Apple Mail.
The greyed out boxes appeared — this is what I am thinking in the cool rational air of the new day — because Mail.app knew that I had a certificate for one email account but not for the .Mac one. It has absolutely nothing to do with iChat and its new certificate.
Although the .Mac/iChat certificate is interesting in a number of ways. See the comments and the entry on “More on the .Mac/iChat certificate”.
It seems that the new encrypted iChat feature in 10.4.3 adds a digital signature to .Mac emails as an extra bonus.
David Dunham emailed with something he noticed:
I just noticed that a digital signing and an encryption gadget show up when I choose a .Mac account in Mail.app. (Encryption isn’t enabled unless I send only to people for whom I have a certificate, which is essentially nobody.)
I tried this out, by replying to him.
Sure enough, the digital signature boxes appeared. His .Mac certificate was visible in my Keychain, but the digital signature options in the Compose window were greyed out and stuck on “unsigned” mode:
What does it all mean?
An explanation from Apple of how the iChat certificates work and more general ignorance from me about encryption follows the jump.
