politician talking to skeptic security expert
Politician: We need access to some communications between x and y ... give us the master key
SecExpert: There is no master key ... Let me tell you how it works ..
Politician (thinking in the mind) : Oh! She started again!!
Politician: Lets cut to the chase .. give me a way to access communication between x and y .. whatever it takes..
SecExpert: I do not own the keys for the communication ... the keys are owned by the users and its a breach of trust if i give it to you.
Politician: Do you know whom you speaking to? How come you do not trust us ?
SecExpert: Maybe I trust you but i do not know how can i trust the institution and its future staff from misusing this powers ...
Poitician: How can you not trust the constitution makers? We ll amend the constitution and we ll see you then.
Meanwhile, in the other part of world:
Terrorist1: Shall we use whatsapp to send messages?
TerroristSecExpert: What! Are you mad? We ll use this android app which i developed in past few days which uses our own generated public/private key pairs.
Terrorist1: I want those poo emojis in that app ... do you have it?
TerroristSecExpert (rolling her eyes)...
