You will need to provide the keystore password ( protected). The command below export the private key to the file serverkey.pem: openssl pkcs12 -in server.jks -nodes -nocerts -out serverkey.pem The Java keytool does not support export of a private key therefore we will need to use OpenSSL. #1: ObjectId: 2.5.29.17 Criticality=falseĬonfigure your webserver to use the certificate and you will be able to check the certificate in a browser.Įxport the certificate private and public keys The snippet below shows the partial output only with the Subject ( Owner below) and SubjectAltName ( SubjectAlternativeName below) fields. The command below will list certificates in the keystore: keytool -list -v -keystore server.jks -storepass protected keystore server.jks -storepass protected -deststoretype pkcs12 \ The command below will create a pkcs12 Java keystore server.jks with a self-signed SSL certificate: keytool \ Recommended to configure the following values (where applicable): The full list of supported values listed in RFC 5280. RFC 2818 recommends to use the SAN certificate instead of a regular SSL certificate :Īlthough the use of the Common Name is existing practice, it is deprecated and Certification Authorities are encouraged to use the dNSName instead. These values added to a SSL certificate via the subjectAltName field.Ī SSL certificate with SAN values usually called the SAN certificate. The specification allows to specify additional values for a SSL certificate. The Subject Alternative Name (SAN) is an extension the X.509 specification.
