    Author: I brought this topic also considering the coming of GDPR. Certainly the attention of the governments to the surveillance and total control of communications increases the relevance of it.

    I think given the current political climate, encouraging developers to think about encryption is a good thing. Especially if you also encourage them NOT to write their own crypto code.
