For the geeks, I hope you got this one ;)
For the non-geeks:
- Wolf was using his key to encrypt files, sign emails and such. Now that it's been "compromised" (in his mind), he needed to publicly invalidate it by sending out a revocation certificate (which he trusted Jan with).
- API, or "application programming interface", defines how things (programs, or in this case, persons) communicate with each other. "Full access" simply means having unlimited control to said communications.
- Ahhh, too complicated. Just enjoy spinning Amber.
