An Eyeful of gnuPG

Показать описание

GNU Privacy Guard (gnuPG) is an open source tool which allows you to create and manage both your symmetric and asymmetric encryption keys. It does a lot more than that, it can also be used to both encrypt and decrypt documents, email and messages. It has facilities to sharing your public keys with special key servers so people you want to communicate with can use your public key to encrypt messages they want to send you, while you can download their public keys to encrypt messages you want to send back to them.

gnuPG runs on almost any platform and is compatible with its progenitor OpenPGP

AI Image: Yep, its another AI generated image of the "Eye of Horus" the ancient Egyptian symbol for protection. The colors represent the shifting sands of security and privacy.

I hope this wasn't a senior moment: For asymmetric keys: the Public Key is used to encrypt, the Private Key is used to decrypt

This just came in the perfect time for me. I'm adding a feature to the app I'm working on to encrypt a generated PDF using GPG key before emailing it to the user. Thank you.

19:05 Isn't it the other way around. Public key to encrypt, private key to decrypt.
I think signing is the way you described.
Great video anyway, I always learn something from them.

I’ve been using PGP since the original incarnation, and use GPG quite a bit. It’s still complicated.

Great video ty very much, I was hoping it would include the new ADSK feature, I've seen no other video approaching it...

Thanks for going over this. I've used this to generate keys for 3rd parties, but I've never really learned how to use it. Do you prefer zsh or did it come with your kde setup?

I've used gpg for years and i still get confused. I thought async used the public key to encrypt and the private key to decrypt. That way you need a private key to access the file
