How to convert a PKCS#12 to JKS
Most of system administrators use OpenSSL (which is not a good idea, but it’s an another story) to manage their PKI. While OpenSSL is good to create/convert X509 certificates from PEM/DER to PKCS#12 (and vice versa, for sure) it doesn’t understand the JKS (Java KeyStore) format. JKS are used in Java world, for example Glassfish application server, OpenDS and so more. In this post, I’ll explain how to convert a PKCS#12 to a JKS using portecle. portecle is a small, but very useful application (written in Java) to manipulate keystores.
- Download portecle, extract it, and lauch it using
java -jar portecle.jar(note that Java 6 seems required for version 1.4.x)
- Open your PKCS#12 file, provide the password
- Click on Tools/Change KeyStore Type/JKS menu
- If you don’t want to use the default password (which is password), click on the menu keystore password
- Save it, that’s all folks!
You can know list the contents of your JKS using keytool:
% keytool -list -v -keystore yourkeystore.jks
