Signing a Digital Certificate Using the keytool Utility
After creating a digital certificate, the owner must sign it to prevent forgery. E-commerce sites,
or those for which authentication of identity is important can purchase a certificate from a
well-known Certificate Authority (CA). If authentication is not a concern, for example if private
secure communications is all that is required, save the time and expense involved in obtaining a
CA certificate and use a self-signed certificate.
1. Follow the instructions on the CA's Web site for generating certificate key pairs.
2. Download the generated certificate key pair.
Save the certificate in the directory containing the keystore and truststore files, by default
domain-dir/config directory. See
“Changing the Location of Certificate Files” on page 112
3. In your shell, change to the directory containing the certificate.
4. Use keytool to import the certificate into the local keystore and, if necessary, the local
truststore.
keytool -import -v -trustcacerts
-alias
keyAlias
-file server.cer
-keystore cacerts.jks
-keypass changeit
-storepass changeit
If the keystore or private key password is not the default password, then substitute the new
password for changeit in the above command.
5. Restart the Enterprise Server.
