@nlawalker its quite verbose and long (like most RFCs) but you have all the information you may need about X.509 certificates's format on its RFC:

I like to go to a coffee from time to time and somedays work alone at home or so, but one of the things I like on coworking spaces is that you can usually have a desk with a monitor, keyboard, mouse, etc. not being limited to work on your notebook's screen/keyboard.
Another nice issue is that you also usually can use meeting rooms for video-conferences or even receive a client/partner.
A minus from coworking spaces is that your subject to its own environment, sometimes you have to much noise and so on... for instance, the place were I use to stay is excellent but they have the radio on all day, what sometimes annoys me!
Summing up, I like to have a desk on a cowork which I use most of the days but also being able to work sometimes alone at home or on a coffee and even on a client's office, together with the client/team.
