A Java KeyStore file is a repository of certificates public key and corresponding private keys. The second line gets a KeyStore instance, and I specify the type used is the default type. It is not very much, but it can be extended and incorporated into a real-world web application, where a service will be dedicated to do authentication and creating the JWT tokens, while other services can consume and verify the JWT token. And I have included this mock KeyStore as part of the sample source code. All it does is create the JWT token, encrypt, then decrypt.

The purpose is to demonstrate how JWT token is created and protected.
The most important part is the dependencies. For this tutorial, all we need to know is how to create one Java KeyStore file with just one RSA certificate and its corresponding private key.
The object named ” key ” is the private key used by the signWith in previous code sample. All these will be explained in this article. And it is very easy to create the JWT token. All I have done in this article are:.
What the above command does is to create a keystore with one RSA key in it. The first line defines the string that represents the password. What this command does is specify the jks file, the alias of the key, and the output file which is called ” hanbotest.
They can be used for SSL transportation. The next step is to export the public key as a separated entity. In order to load, one must supply the password associated with the JKS file. The last line extracts the private key out of the KeyStore object. Private key is something to be protected, and public key can be shared to other parties.
This is the only hard part of this tutorial. I had to include the three jackson jar files. It is not very much, but it can be extended and incorporated into a real-world web application, where a service jqr be dedicated to do authentication and jsr the JWT tokens, while other services can consume and verify the JWT token.
In between, we need to find a way to create the JWT token unencrypted. If a token can be decrypted correctly, then all we care about is the body portion of the token.
As promised, I have kept this article short and easy, simple and fun. The method has 4 lines:. When a request comes into my micro-service ecosystem, the request will first be authenticated.

And you will have https enabled for these application containers. Here is how it is done:. The service that handles user request needs to decrypt the token, which can use the public jjtw to do this. When it is typed in, and hit enter, it will prompt for password. To create a new Java KeyStore file, here is the command:.
The second line gets a KeyStore instance, and I specify the type used is the default type. User credential will be sent to the authentication and authorization service first, which can look up the user in database, and verify the credentials, then send back an encrypted JWT token that contains the user information.

This is done using the public key. I wrote a simple Java console app that demonstrates the encryption of the JWT token using the private key. The string contains three encrypted sections. Jkwt I have included this mock KeyStore as part of the sample source code. The sections are token header, body, and signature.
