Topic: Cryptography for common and ignorant users as one ... (Read 75 times)

Good, here a SEO writer and Internet journalist.

First of all, sorry about my bad english.

I would like to write and publish something simple about cryptographic tools allied with security and privacy.

But access to information, as well as the installation and configuration of many cryptographic mechanisms, are a real challenge for the normal and ignorant user, if not impossible.

It seems to be - yet another practice in the domain of code experts, mathematicians and academics.

It all started because I wanted to try PGP ... Impossible for a donkey user as one.

I throw some questions, to which more silly:

How does the ignorant user know if one system is better than another in terms of privacy or security? Do you believe who? To the hacker of a blog? To an academic expert from a university? Snowden? How to identify references?
 
If in the future cryptography becomes accessible and massive, surely the networks and communications would be more secure, private, free. If one learns and manages to adopt these systems, what happens if the others with whom we communicate do not want to use it?

Which of the following systems / tools / networks are recommended and which are not?

PGP
Tor
Keybase
I2P
IRC
Briar
Mumble
Signal
Wire
Tribler
RetroShare
VPN
Remailers
Badger
Ricochet
Bitmesssage
GNU
Psyed
Anonimize
Secushare
Hushmail
Protonmail
Thunderbird
