Generate self-signed PKCS#12 SSL certificate and export its keys using Java keytool and openssl.

Steps to generate self-signed PKCS#12 SSL certificate and export its keys:

1- Create PKCS#12 keystore (.p12 or .pfx file)

keytool -genkeypair -keystore myKeystore.p12 -storetype PKCS12 -storepass MY_PASSWORD -alias KEYSTORE_ENTRY -keyalg RSA -keysize 2048 -validity 99999 -dname "CN=My SSL Certificate, OU=My Team, O=My Company, L=My City, ST=My State, C=SA" -ext san=dns:mydomain.com,dns:localhost,ip:127.0.0.1
  • myKeystore.p12 = keystore filename. It can with .pfx extension as well.
  • MY_PASSWORD = password used for the keystore and the private key as well.
  • CN = commonName, it will be shown as certiciate name in certificates list.
  • OU = organizationUnit, department name for example.
