   You will be required to input keystore password. Then verify the entry with alias is removed from keystore.ssl.

   keytool -list -v -keystore keystore.ssl

2. Create new certificate.

   keytool -genkeypair -alias datacentermanager -keyalg RSA -keystore
   keystore.ssl -dname
   "CN=MYDN,OU=MYORG,O=MYCMPY,L=MYADDRESS,S=MYCITY,C=CN" -
   validity 365 -storetype pkcs12 -keysize 3072

   Also, verify the entry with alias is inserted into keystore.ssl.

   keytool -list -v -keystore keystore.ssl

Note:

If you want to install a certificate from a Certificate Authority, please follow the steps below. Keytool is in the JDK package and Energy Manager keystore.ssl file is in its installation folder. The cert alias should be datacentermanager.

• Create a certificate request: keytool -certreq -alias datacentermanager -sigalg MD5withRSA -file server.csr -keystore keystore.ssl

• Submit the file server.csr to the Certificate Authority to sign it.

• After you get the certificate from the Certificate Authority, please import it into Energy Manager keystore.

  • keytool -import -v -trustcacerts -alias root -file -keystore keystore.ssl

  • keytool-import -v -trustcacerts -alias datacentermanager -file -keystore keystore.ssl
