Excellent video and very clear, concise and to the point. But it does highlight exactly why, in 2020 very few people encrypt anything at all. In my experience, encryption will only be universally accepted when it becomes brain dead simple to implement - better still, vendors have it configured in their products right at the installation stage - and it is cross platform - and it is compatible with 'everything'.
If I encrypt, for example, my phone conversations and email today, the vast majority of the people I need to contact wouldn't be able or willing to setup their system to allow them to communicate with me.
Great video though - I have often tried explaining public/private key systems and failed - now I can redirect folk to your video: -)

I wonder if you can break the code by encrypting a whole screen of the same character and comparing it to the result encryption. then running through the whole alphabet by repeating this method and observe for a pattern. Even keep encrypting the same message over and over to see if it spits out the same code every time. If it gives a different encryption every time, surely you can assume Time stamp is included in algorythm. Turn system clock back o different time then turn off comp pull plug for a minute plug back in and try again to see if it using the system clock or Internet time if you suspect it uses timestamp.

Does this require perfect trust in the authors of the apps used? It seems like the software holding the keys could be a way for whoever wrote the software to be able to decrypt messages you receive or send encrypted messages in your name to anyone else, no? Could the email programs have access to keys to do the same thing? Ditto for anyone who hacked your computer or phone? Google wrote Android, could they potentially have some back door?

Gpg4usb is better then gpg4win.
Linux doesn't run the gpg4win.
Gpg4usb runs on Windows and Linux.
Open source is a must and a 4096 bit key is almost a must, 2048 bit key is a minimum.
Phill Zimmermann sold his secrets with a gun in his ear.
PGP is not open source and that is why Phill Zimmermann is alive.

takes while for new info to sink in. terms of words. just doing it. second time i get how it works. haha. i used to learn law. takes time to adapt you just have to read and break it down simple. you cant explain law to p people with out looking crazy. courts such use it against you as well. insanity.

The problem with RSA is, that it's compromised. There is a macroscopic flaw, which is known to a few Governments. You can't trust your privacy, because due to this flaw, the private key can be derived from the public key in a matter of seconds, with a normal PC. Let alone dedicated hardware.

For Ham Radio, is it still illegal to encrypt your signal? I have been wanting to set up a system between 2 specific locations with my HF Transceiver but I want to have the ability to have voice encryption capabilities. Is there any products that would work well with an icom 7300?

Hi Rob, Great tutorial! Ive also watched your video on protonmail. As I understand it, protonmail encrypts end to end, is this true? Would you recommend using thunderbird as a front end for protonmail or continue using the protonmail web gui or app?

What do you think of signing other people's public keys on a public key server? This seems to be standard procedure to validate public keys and establish a -web of trust-, but won't this disclose your social contacts?

Thanks for sharing. Of course if the GPG software has a built in back door then your encrypted message can be deciphered by that software developer. The only 100% safe encryption software is one you build yourself.
