Convert Java Keystore to PEM Format - A Step by Step Guide

How to Convert a Java Keystore Into PEM Format

Java Keystores are highly secure formats used to store private keys and certificates, and they are commonly used for SSL/TLS encryption. If you need to convert your Java Keystore to the PEM format, there are several steps you’ll need to take in order to do so. Here is a quick guide to help you through the process.

Step 1: Extract the Private Key

The first step is to extract the private key from the Keystore. To do this, use the following command:

keytool -importkeystore -srckeystore myKeyStore.jks -destkeystore keystore.p12 -deststoretype PKCS12

This will export the contents of the Keystore into a PKCS12 format. You’ll then need to enter the password for your Keystore when prompted in order to access the private key.

Step 2: Convert the Private Key Into PEM Format

Once you’ve extracted the private key, you’ll need to convert it into the PEM format. To do this, use the following command:

openssl pkcs12 -in keystore.p12 -out keystore.pem -nodes

This will convert the private key into the PEM format, allowing you to use it as needed.

Conclusion

Converting a Java Keystore into PEM format is a relatively simple process, but it requires a few steps in order to ensure the security of your data. Following the steps above should help you quickly and easily convert your Java Keystore into PEM format.
