About PFX to JKS Conversion

PFX/P12 (PKCS#12) is a binary format commonly used on Windows systems to store certificates with private keys. JKS (Java KeyStore) is the native keystore format for Java applications like Tomcat, WildFly, and Spring Boot.

Converting PFX to JKS allows you to use Windows-exported certificates in Java-based servers and applications. This is commonly needed when migrating from IIS to Tomcat or deploying certificates to Java microservices.

Common Use Cases:

Note: For security, this conversion should ideally be done locally. The equivalent keytool command is:
keytool -importkeystore -srckeystore keystore.pfx -srcstoretype PKCS12 -destkeystore keystore.jks -deststoretype JKS

Convert and package keys for SSH, TLS, and keystore workflows.
