![]() ![]() This article provides information and examples that aids programmers using Real-Time APIs (EMA and ETA) - Java Edition. This article will demonstrate how to generate a new keystore file, view the keystore file’s content, import a certification along with EMA Java API walkthrough. Fortunately, Real-Time SDK Java prepares a solution for you to use the keystore file. However, the client side needs its own HTTPS implementation to make requests and to receive information securely from the server. For many server application, HTTPS is handled by the server side such as the Web server, Refinitiv Real-Time Distribution System component (ADS) integrated with SSL Accelerator. HTTPS is vital to securing end-to-end interactions. Secure Sockets Layer (SSL) and Transport Layer Security (TLS) are developed in order to serve this purpose in the HTTPS protocol. If the contents of the data in that packet are sensitive – authentication information, confidential insider data – the sender would probably like to ensure that only the receiver can read the package, rather than the packet being readable by any router along the way. certreq -keystore server.As a packet can and probably will pass through many routers (and network components) between the sender and receiver. Note: copy the -ext parameter value from the command that creates the SAN certificate. You are welcomed to send the CSR to your favorite CA. The command below will export the Certificate Signing Request (CSR) into myserver.csr file. The SubjectAltName field with all values: IP - List of IP addresses of your server.The command requires the following values for the SubjectAltName field (where applicable): ext command requires the following values for the Subject field: dname "CN=,O=myorganization,OU=myou,L=mylocation,ST=California,C=US" \ genkeypair -keyalg RSA -validity 395 -keysize 2048 -sigalg SHA256withRSA \ How to create the CSR for the SAN certificate Create the SAN certificateįirst create the SAN certificate with all values: keytool \ The command below export the public key to the file servercert.pem: openssl pkcs12 -in server.jks -nokeys -out servercert.pem 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. Explaining how to create the Certificate Signing Request (CSR) for the SAN certificate using the Java keytool.Explaining how to export the certificate private and public keys using OpenSSL.Explaining how to create the SAN certificate using the Java keytool.We will learn how to generate the Subject Alternate Name (or SAN) certificate in a simple way.
