keymanager.instance = SunX509

# Enable/disable the validation of messages (true enabled, false disabled) - for requests and responses
schema.validation.request = true
schema.validation.response = false

Creating your own java keystore file

• Please read https://www.nic.cz/page/744/registracni-system/.
• At first you need your own private certificate and key and public certificate of the server. For open instance you can use this private key https://www.nic.cz/files/nic/doc/pristupy_openinstance.zip.
• Credits to https://www.wowza.com/docs/how-to-import-an-existing-ssl-certificate-and-private-key#convert-the-certificate-and-private-key-to-pkcs-12.

Step 1 - Convert the certificate and private key to PKCS 12

openssl pkcs12 -export -in Cert_openinstance.pem -inkey privatekey_openinstance.pem -out private_key.p12 -password pass:changeit

Step 2 - Import the certificate to the keystore

keytool -importkeystore -srcstorepass changeit -deststorepass changeit -destkeystore fred.jks -srckeystore private_key.p12 -srcstoretype PKCS12

Step 3 - Get server certificate

Note: works only for open instance environment - on production instance you'll get certificate from CZ.NIC.

openssl s_client -connect epp.demo.regtest.nic.cz:443 2>/dev/null </dev/null | sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' > server.pem

Step 4 - import downloaded certificate to keystore

keytool -import -alias server -file server.pem -storepass changeit -keystore fred.jks

Usage

• Add as Maven dependency (or use .jar) to your project. Create instance of FredClient class, properties file as parameter.
• Feel free to call any command, no need to call login separately, because:
  • Every command checks for connection via hello EPP command,
  • if connection is not established, it creates new ssl connection to server,
  • proceeds login EPP command and try to login,
  • proceeds command you wanted.
• If you keep your current instance of FredClient class, it reuses created connection.

Enjoy!
