how to: convert pfx to jks

A Java KeyStore (JKS) is a repository of security certificates, either authorization certificates or public key certificates, plus corresponding private keys, used for instance in SSL encryption. Some times the SSL certificate is issued for IIS server which originally contains the CSR of the certificate. SSL certificate process is completed in IIS Server. The certificate and private key can be exported as PFX. It can be used on other servers like tomcat, apache, nginx, etc.. To accomplish this, you need to convert pfx to jks.

There are multiple methods available and each server follow the suitable method. The PFX can be directly imported to keystore which already exists by using the under given command.

keytool -importkeystore -srckeystore “D:\windowstechupdates\Test.pfx” -srcstoretype pkcs12 -destkeystore KEYSTORE.jks -deststoretype jks -deststorepass password

This will import a PFX in already existing .JKS store file.
