GnuPG Key Upload To Keyserver 2021_12_13_06:45:21 (2023)


This video will show you, that you can easily upload your GPG public key to any publicly accessible GPG key server.

#linux #gnupg #gpg


All right, the topic of this video is how to upload your keys to one of the key keys means gpg key what you have created and to make things go global, so people can find you and your keys.

So you need to upload that key in one of the many key server several jpg key servers available and those key servers are eventually, if you uploaded in one of them a popular one, it will eventually get synced with the other popular key server.

So, basically your keys gpg key will be accessible across the globe by whoever wants to address access that.

So it's a good way to to to build a trust.

So people people know the keys are coming from the person okay.

So it is quite a mandatory to have a gpg key for some sort of project because they want everything to be signed by the their gpg.

But having is it's a good thing? I'm not vouching, for it will enhance the security, that's the other department.

Other people will look into it all.

I think it what it does it.

It gives you the kind of understanding if it says it is coming from here.

It is coming from here.

Okay, so the keys are basically unique to my understanding.

There might be some other very in some other way, some other problem that those who have got much more knowledge and deep into the security stuff.

They could have told you much more, then.

I cannot add this in this video.

If I know that also, but in basic understanding, I do use it.

I have one I use it everywhere.

I sign my mail.

I sign my git commits I I do all this stuff whenever, whenever the key is possible, I I have uploaded it to the servers many moons ago and it gets synced to all the key servers to without further ado.

Let me show you it: it's just a three line of script.

Um cat.

I mean this is an automated way of doing thing.

You can do it by hand, it's very, very, very ordinary, okay, it seems I'm starting to mistype a bit send keys or still I I sometimes fail to remember what I mean.

Okay, so to clear the screen, let me so this is the stuff in server you can you can you can put as many server key server.

As you know, I have just demonstration purpose put it to here: okay and just look through it, and this is heavily tweaked random keys.

This is not mine, of course, but I just show you you can place it, so you can run this script and it will upload it to the server whatever you have mentioned here in the server column right, it's very darn easy.

It should be up there in the github.

If it is not it's just one simple ordinary for loop right, all you have to just use the gpg tools, this keyword key server and send keys.

That's all if you run gpg to help those things will be shown to you right, simple stuff, to get it okay, so the basic idea has, you should have one digital key for yourself: okay and you use it whenever it requires to be used, or you should use it in some case because you might be getting you are you people already know that some projects require a requirement as stringent they want the individual gpg keys or some of the project has got their own gpg key some linux distribution even kernel, so our kernel has been signed by linus and other people also, so so so it is, it is.

It is a good thing to have.

Okay, I cannot trace it on the word mandatory wish.

I could, but it's a good thing to have in your repertory, and you should use it if you have one, if you don't have one, please go get it.

Internet is littered with that kind of information.

Okay, so, and if you have that you, you can easily search it here, you go to dot.

It is one of the key server pgp.mi and you put your username area.

I mean your your email address or your your public key here and search it.

Unfortunately, this server 99 time out of 100, always timed out.

I don't know why there must be some infrastructure issue behind this okay, so it is one of the key server popular one which ultimately gets sync if you pop drop it to other other key server.

Uh here is another one get your.

Ah, there is upload link you can you can easily easily upload upload your key from here? Okay, if I, if I start see, I have already done it right, so this is, if I search it say it is found right, because I have uploaded it here as simple as that, so it found it.

Okay, if I click on that, it will ask me to save on save this, which I don't want to so this is the way I mean you can you can easily? You can easily get it to get, get things uploaded and you can read it here on the general gpg handbook it is uh it is.

There is a there is a.

There is a section which is calling distributing keys.

You can you can see.

There is an these options.

There send keys and key server receive.

If you, if you want to get some somebody's key, you can get it from there also okay.

This is how it should be done, and this is how it should.

If you want to get someone, there is an example.

You should follow.

Okay, this is a good thing, good thing to have again, I'm saying I'm not saying it will elevate the security stuff, and that is due to my lack of understanding about the what the security and, in a broader sense, in a deep sense.

You can say so.

I have one from 2008 and I have changed it two three time and permanently settled down on single one.

So it's it helps you to get network of tasks.

Okay, if the key is long time attached to you your identity in nowadays, so people will be assured that this key is attached to this person.

That is, this is coming from here.

It's an eutopian view.

I know that a lot of you people say no, no, this can be compromised and, yes, it is possible, it could be compromised.

There is several other ways, but still this is the standard way if, if a key attached to a person for a certain long time until unless something bad happen that so so there is that there is a trust build out of it.

Okay, so this person having this this is coming from, so people get some sort of assurity.

Okay, I don't know how strong that actually is, but they get actually okay, so uh, if you don't have one, please get get one and upload it to any of the key server of your choice.

Okay, I'm not going to show you how you can create a gpg key of your own, because internet is basically littered with that information.

Ok, and if you, if you do not want to get into that all that hassle, chain fpg and go to this side and for your sake, read it.

Okay, read something where, where you can, you can get some sort of idea how it could be done.

It's very easy believe me, it's very easy and it doesn't take too much of your time but make sure you follow the step.

What has been said to you while making it okay and take some judicious call, it will help you, okay, so I think it's enough for this, this video.

I hope this will be useful to someone.
