Turn a certificate, its private key, and an optional chain into a Java KeyStore (.jks) file for Tomcat, WildFly, and other Java application servers — no keytool command line required.
Your leaf certificate, matching private key, and any intermediate certificates.
The alias name and keystore password your Java server config expects.
Built locally in your browser — verify it with keytool -list -v -keystore before deploying.
A Java KeyStore holds a certificate and private key for Java application servers like Tomcat and WildFly to use for TLS.
No — it's Java's own proprietary, reverse-engineered format. This tool matches that reverse-engineered spec closely, but always verify with keytool -list -v -keystore yourfile.jks before relying on it in production.
No — the keystore is built entirely client-side in your browser; nothing is transmitted.
