1- what does "use NAME as default secret key" do in Kleopatra tool options?
The reason why I ask this, is I have a looooong password for my certificate. And apparently this becomes a hassle when encrypting several files. So does the option in question replaces my long passphrase with my name? is that what this is?
2- One more thing, I encrypt my files to upload them to dropbox, I don't need to sign them, right? It's just my own files, not sending them to anyone.
3- and lastly, will it make a difference to use long or short passphrase when creating a certificate? Now that I think about it, the file is going to be RSA 4096 encrypted! What difference does the passphrase make?
PS. A recommendation of (current, up to date) 3 Information Security books would be VERY helpful. I don't want to make a separate question just for this :) 1 or 2 Beginner level (introductory) 1 Intermediate 1 Advanced
Double Thanks :)
So I've read the documentation (that I found by coincidence when looking for something else)
Answers to my own questions (for future users who might have the same question):
1- Still needs an answer!
2- Signing is used to let others know that I truly was the one to send the file. So no, I don't need to sign it when just backing up to dropbox.
3- Passphrase is used as a layer of protection for MY OWN certificate. Say my computer was stolen, or that a hacker got a hold of my certificate file, that passphrase is what will protect my certificate from unauthorized access and thus the hacker won't ever be able to forge sent data and pretend to be from me. The longer that passphrase the harder it is to crack.
QUESTION 1 still needs an answer and books recommendation is even more important now. This is an AMAZING science :D
