Necessitate sign request

okay so the eight of us for signature is a signing key which is used for most HTTP requests to AWS one of them what I am going to talk about in this video itself is more so for personal use maybe even educational purposes or you know maybe even information base because I do have another video which is uses a faster more simpler item it is a github repository pushed out by aw slimes themselves which basically makes a lot easier to do AWS for signature signing I'd recommend you watch that if you want a faster implementation of the AWS for signature may require a little bit more knowledge about maven dependencies you know stuff around that nature nothing crazy but this video in itself is more so about hey if I didn't have any dependencies and I just wanted to create the AWS force signature as they say because they do they give you examples on how you can do it yourself and it's fairly straightforward but it's anytime you're doing signing it's kind of annoying because you can make one mistake and that will bleed it to the other options and just make things hard on their own so the point being here this is more of a kind of Avenue you could use for an AWS for signature but it's not the best and the reason why I say this is because about five months ago I wrote my own ad of this AWS 4 signer it was really annoying it took a while couple it took like three or four days um I did not know at the time that there was another dependency or library I could have used so keep in mind the reason why I did this really was because I wanted to use AWS for seiner with my own client thinking was using rest assured and I did not want to use some type of API because AWS does have api's and different items that will do the same for you but I wanted just a signature so if you want an example what I'm talking about hopefully this sounds somewhat familiar to you if not then you might have to research some things before you dive into this but you know you send an HTTP HTTP request and as you can see here this is the I'm just using a dummy example google comm if you know anything about you know TCP and HTTP requests not TCP but baby pee yeah to send your headers and the most important and most annoying thing that you are going to be doing is making the AWS for signature itself which is this right here this is the signature this is a dummy signature that post my postman makes they have their own I guess way of making the signature it does work I've used it with AWS but this is just simply to show you the example this is what the headers look like this is what you need in order to communicate with AWS so for example you will have your access key and you will have your secret key and those two along with some other things will create the signature itself so as you can see here this is something that if you were to implement this yourself this is probably what your function would look like takes in the secret key takes in a simple date format your HTTP method all these different things that will then the internalizing use with the AWS for seiner I also recommend you read the actual AWS documentation it's pretty good for information sake you know for example like service name you have to have a service name but what if you don't have a service name I'm pretty sure you can use null or empty string same thing for payload as you can see I have empty street for payload and I think that's forget request you can do that so it's you know there's just a couple of things and as you can see here this I wrote it myself pretty much is following the AWS tutorial it's pretty good it's a pretty good learning experience it's definitely not the most convenient item it's definitely not the most you know non you know it's not succinct it's very verbose but I liked it it was pretty cool it was a good learning experience as you can see here this is pretty much you know what they proposed but I definitely would recommend I'll put this in the description this link right here it is a Java query guest forum post website goes whatever it is written by Vicki the core really really really really really good if you wanted to you could actually take this right here this entire piece of code and paste it into your idea of choice and it would work it would actually work it would be you know a good learning experience it's something that you could use so if you want to and you say hey you know what I'm lazy I just want to you know really quick just do some AWS requests I'll learn about making it myself later if you want to learn about making it later you can go ahead copy this use it for validation purposes because like I said there's a lot of you know hashing algorithms and stuff where you can make a mistake I definitely made a mistake I made multiple online fixing those mistakes and basically I just figure out that you know what you're doing making wrong and how to do it right so I definitely would recommend you check this out this is a really good resource just to understand the idea aw it's for signature as well as you know a good example you can win this you could see what the signature is supposed to be I believe AWS also offers a signature validator I'm not if I if I remember correctly I think they do if not you could use this as a validator and then this is like a little test class showing how he sets his stuff up and then runs it and you know what this is with I think with elasticsearch but the reason why I even mention this the reason why I even say this that's something that is interesting is that this is the pure signature this is the signature meaning anything you want to use you could use so it may give you some freedom in the past I used rest assured now I'm not you know tied to rest assured I don't love rest assured I really could care less now but a thumb was using rest assure so what I did was the rest assured they have a matter method I added the header with the signature whatever headers I want a boom it worked I convenient you can use whatever client you want to use for some reason your applications using some client heavily and you need the signature you want the signature then you can do it this is it you can get the signature through this means you write it yourself you use it yourself and like I said I will include this URL because it's a really good resource just for validation purposes just to make sure you're doing it correctly but if you're not married to the client if this is a learning experience where you just want to know what's the best way for me personally I was interested in what is the best way for making an HTTP request to AWS just basic HTTP requests through the SDK the answer would probably be if you're not trying to a client would be the AWS request interceptor which is proposed by AWS labs it's not on made them yet I wish it was and this is probably the easiest way basically using Apache HTTP for foot-post yeah but I'm planning on making a separate video about that but either way this is the kind of you know kind of very amateur green or even you know you can be professional you if you really want to use your own implementation of getting the signature and then putting it to your HTTP HTTP requests you could do there there's nothing wrong with that it's just very verbose and as you can see the one I wrote like five months ago is pretty long and it is even just to initialize it pretty annoying and you have to have a lot of different variables and you have to know what you want and what you're trying to do and it is going to take a little bit of trial and error just to get everything up and running but hopefully this video at least serves as some type of a point of information for these signature and that URL I provided this pretty much I won't say exactly the same as me because I wrote this before I found that URL use that URL for validation but it's very similar it's literally what AWS proposes to they have their own tutorial it's all text-based and it's a good resource itself but I feel like if you're given an example to at least run in your IDE you'll have a better chance of success and not getting frustrated when things don't work out so links in description for the URLs and stuff and also include the other YouTube video planning on making with the request interceptor as well
