I recently had to use a PFX certificate for client authentication, and for that reason, I had to convert it to a Java keystore (JKS). In this post, we will learn how to create both a truststore and a keystore, because based on your needs, you might need one or the other.
The difference between truststore and keystore, if you are not aware is, according to the JSSE ref guide:
I’ve been working with the AS2 Protocol and the AdroitLogic AS2Gateway for quite some time now, and hence, playing with JKS has been a must.

In this blog post, we’ll go through a couple of simple commands on how to do that.
A JKS is an encrypted security file used to store a set of cryptographic keys or certificates in the binary format, and it requires a password to be opened. JKS files are used for a variety of security purposes.
