To create a PKCS12 keystore, and we should, the command is the following: keytool -genkeypair -alias springboot -keyalg RSA -keysize 4096 -storetype PKCS12 -keystore springboot.p12 -validity 3650 -storepass password Let's open our Terminal prompt and write the following command to create a JKS keystore: keytool -genkeypair -alias springboot -keyalg RSA -keysize 4096 -storetype JKS -keystore springboot.jks -validity 3650 -storepass password Generate an SSL certificate in a keystore JKS used to be the default choice, but since Java 9 it's PKCS12 the recommended format. The two most common formats used for keystores are JKS, a proprietary format specific for Java, and PKCS12, an industry-standard format. To enable HTTPS, we'll provide a Spring Boot application with this keystore containing the SSL certificate. The keytool documentation defines a keystore as a database of "cryptographic keys, X.509 certificate chains, and trusted certificates".
Generate a self-signed SSL certificateįirst of all, we need to generate a pair of cryptographic keys, use them to produce an SSL certificate and store it in a keystore.

On GitHub, you can find the source code for the application we are building in this tutorial. For more information about this utility, you can read the official documentation. Note that if you are on Windows, you might need to launch it from the \bin folder. To check it, try running the command keytool -help from your Terminal prompt. Keytool is a certificate management utility provided together with the JDK, so if you have the JDK installed, you should already have keytool available. Throughout this tutorial, I'll use the following technologies and tools: If you have already got an SSL certificate, you can follow the step 1b. If you don't already have a certificate, follow the step 1a. Distribute the SSL certificate to clients.

In either case, we're going to see how to enable HTTPS in a Spring Boot application. In production, we should use a certificate issued by a trusted Certificate Authority (CA). Its use is intended just for development and testing purposes. We can generate an SSL certificate ourselves (self-signed certificate). Setting up HTTPS for Spring Boot requires two steps:
