Encryption!
Q.
Does that that mean you're a terrorist?

[gently]
A.
No - it means:-

  • the people I email and supply code to can be certain it came from me - and that it has not been altered.
  • if anyone gained access to my computers the passwords and information can't be read.

Q. But I heard if you've done nothing wrong you have no need to hide anything?

[gently]
A. Did the person that told you that

  • have locks and curtains in their house?
  • were they wearing clothes?
  • do they use a bank with security?

Or do they do all their communication by shouting and sending postcards?...
