Hi,
I have not a paranoid security/profile. But I am looking for an average good security/privacy protection. Not minimum, not paranoid, an average one.
Please, allow me several simple questions, and please try to answer in simple language:
1) I have my Modem-Router with a password and WPA2 AES cryptography/encryption.
I read that this can negatively affect computer performance (RAM, CPU, internet speed etc). So, in order to avoid that and improve my computer performance, I want to disable Modem-Router password + WPA2 AES cryptography/encryption. In compensation, in order to protect my security/privacy, I will enable access to my Modem-Router only to a predefined list of MAC addresses (devices). In other words, no MAC addresses (no devices) can access my Modem-Router, if they are not in my predefined list. Also, I hide the name of my network.
Is that "ok"? Or do I need the WPA2 AES cryptography/encryption?
2) I am using SimpleDNSCrypt.
Is DNSCrypt a must? Or is DNSCrypt not necessary?
If it is a must, is DNSCrypt enough? Or do I need something else?
3) I read that DNSCrypt encrypts DNS. But I don't understand the meaning of that in simple language, in my real day.
I know VPN will encrypt all my traffic communications.
DNSCrypt is not going to encrypt my IP, the number of queries, the destiny of my queries etc. But is DNSCrypt going to encrypt at least the content of my traffic communications? (passwords, credit-cards etc). Or my confidential data will be exposed?
4) Why do I need DNSCrypt or VPN, if I have WPA2 AES in my Modem-Router? Does my WPA2 AES prevent "middle-man attacks"?
5) Why do I need DNSCrypt or VPN, if I have HTTPS in my browser? Does HTTPS prevent "middle-man attacks"?
6) How DNSCrypt avoids "middle-man attacks"?
7) I use Firefox, and recently Firefox implemented DoH+CloudFlare.
I understand that DNSCrypt works in all my computer. But do I need to use DNSCrypt for all my computer?
Or is enough to use Firefox DoH+CloudFlare?
8 ) In a Public Wi-Fi, let's say the owner of the Modem-Router wants to steal user credit-cards or private stuff, and he hacks his own device: What happens if I am not using nothing? Does the owner of this public Wi-Fi can steal every information passing trough his Modem-Router?
How DNSCrypt will protect me in this example?
Please, if possible, I will appreciate if you answer me following the number of my questions.
Thank you in advance!
