Unlock The Power Of JWT: Learn How To Generate And Create Your Own Token
In this tutorial, we delve into the fundamentals of JSON Web Tokens (JWTs), exploring their significance, structure, and practical implementation.
We begin by demystifying JWTs, explaining how they work . From there, we dive into the specifics of JWT structure, breaking down its components such as header, payload, and signature.
Moving forward, we delve into the practical aspects of JWT token generation using both HS256 (HMAC with SHA-256) and RS256 (RSA Signature with SHA-256) algorithms in Java. Leveraging the Nimbus library, we provide step-by-step instructions on how to generate JWT tokens programmatically, covering essential concepts such as signing keys and token expiration.
We will also explore token verification techniques, guiding you through the process of verifying token, decoding its claims, and ensuring its validity through code demonstrations,

Functional programming in java 8 with Stream API's [map filter and flatmap]
Thank you so much. I was looking for the same issue and I got the solution here.
nice explanation
If we use embedded broker then do we need to configure kafka prducer amd consumer in separte config file ? As without writing configuration my code is running . In my code all the properties are written in application.properties file only. Please answer
thanks so much for this - it saved me!
Awesome tuturial can you please make a video calling two microservies parellel by using CompletableFuture?
Helpfull can you please provide a github link for the same code
Importantly sir jee
Thank you so much Brijesh!

Very useful thank you so much
Outstanding explanation, straight to the point and easy to understand why, when and how to use Dagger for a AWS Lambda Function. Thank you very much.
Very useful, thanks a lot!
Can we sync previously stored data using this?
What is the gradle version used?
Great explanation - especially for the conditional validation. Better than anything else I could find online
very well explained , danke
Learnt a lot from it. Thanks
Great tutorial, thanks very much. I used it before and it's really useful. But i can't implement it with list of objects in entity, i didn't find any solution for that. Can you please explain how to implement this many to many field in entity? Thanks for advance 😊
can you share githup account for that?
code github link?talk slowly and make more descriptive videos
Hi Sir... your content is appreciable and I'm finding some new/diff way to write Junit test case but I have one suggestion i.e. whenever you are explaining/writing any code/methods/imports you should show it and explain it from which pkg ur importing and what is purpose . if you cover maximum W's then your videos will be super duper...
Good stuff! Congrats
thanks bro
Thanks to this video, i understood monstache. Thank you very much!
Hi, thanks for making such amazing video. I was looking something like this only for quiet some long time. But I have 1 question. How can I connect elastic server with nodejs? Actaully I am using Apollo Graphql for queries and mutations with mongodb. So How can I make a search query with the elastic in nodejs. If you can provide me some guides or any links then it would be very helpful.
Very helpful, thanks a lot
If i have a project in intellij folder and i want to apply a particular logic in service layer.. So can i just write the package and class name, and ask chatgpt to apply that logic in thay class, will it work?
Thanks for the video... am using spring boot app and deploying the same app as 6 instances ..how can i achieve distributed caching between 6 instances of same app
Missing clarity in between
I had found your channel searching about apache ignite. Your lecture is very useful and understandable. Thank you.
Why we cannot use the real kafka brokers in case of Testcontainers?
Excellent explanation
Very helpful. Thanks for the video!
awesome lesson sir! 👍
please provide the git repo
github.com/Brijeshpant/aws-playground/tree/master
Hi, Are you giving any training on serverless apigateway, lambdas, .... Jenkins.
Hi, Thank you very much for this, Currently, I'm trying to implement the elastic search for the Mongodb database, I might miss the tool monstache if I didn't see this.
i was thinking if i could use this technique to query a mongodb database with billions of documents
Very beautiful and clear explanation. Thats what i was looking for!
In the employee.class, Should we just skip @Table and @Entity, @Id (JPA annotations)?
The Mapping is defined within jdbc type github.com/Brijeshpant/ignite-with-java/blob/IGNITE_SPRING_DATA_WITH_PERSISTENCE/ignite-cache-server/src/main/java/com/brij/config/IgniteConfig.java#L59. So no need to add anything in the Entity class
'promo sm' ❤️
Don't know why AWS made API Gateway -> SNS integration so complicated. Thanks for making this video and making my llife a bit easy. You are an awsome human being. 😀
How add ignite core depencies sir.
I don't understand the MongoDB replication part? What are you doing? Do you convert a standalone mongod instance into a replica set, or are you creating a secondary redundant set which is the only set which is used for the changestream? Why can't MongoDB support changestream without replicas? What is the logical limitation?
First part of your question : Yes. I have started the standalone Mongo DB instance into a replicaset. Secondary node can be started in different port(i.e 27018). Second question: Change Streams utilises the replication process by subscribing to the operation log(oplog) of Mongo DB. Oplog is a replication specific feature and it is only generated by Mongo DB when it is running in replication mode. for more info you can read mongodb documentation. www.mongodb.com/docs/manual/changeStreams
where is Apache ignite host:port info in you project ?
can you please increase the font of your handwriting? it's not legible content is good
Hello, Can you please also share the XML configuration for connecting with postgres as external store?
well, what is the case when I'm using a native query? banging my head since 24hrs
Oooh, yea! I was trying to solve this issue in my app for last 2h. Thanks mate that helps me alot.
How did you configure?
