![]() When prompted, enter the password you created earlier (when you created your new keystore). In the command above, your_site_name should be the name of the keystore file you created in Step 1: Use Keytool to Create a New Keystore or when using the DigiCert Java Keytool CSR Wizard. Keytool -certreq -alias server -file csr.txt -keystore your_site_name.jks Step 2: Generate a Certificate Signing Request (CSR) from your New Keystore Your keystore file, your_site_name.jks, is now created and in your current working directory. When asked for a "key password for ", press enter to use the password you just created for the keystore file. When prompted to verify your information, type y or yes to confirm. Are you are ordering a Wildcard Certificate? Then your FQDN must begin with an asterisk (*). Instead, type the Fully Qualified Domain Name (FQDN) for the site you are securing with this certificate (e.g., ). Important: When prompted for the first and last name, DO NOT type your first and last name. ![]() Store this password somewhere safe, such as a trusted and secured password manager.Įnter your SSL/TLS certificate information. Note: You will specify this password in your Tomcat configuration file and then use it to generate your CSR and to import your certificate. When prompted, create a password for your Keystore. The asterisk is not a valid keytool character. When ordering a Wildcard certificate, do not include the asterisk (*) in the filename (e.g., your_site_name). In the command above, your_site_name should be the name of the domain you want to secure with this SSL/TLS certificate. Keytool -genkey -alias server -keyalg RSA -keysize 2048 -keystore your_site_name.jks Navigate to the directory where you plan to manage your keystore and SSL/TLS certificate. Before you begin this process, backup and remove any old keystores. Installing a new certificate to an old keystore often ends in installation errors or the SSL/TLS certificate not working properly. Important: We recommend you generate a new keystore following the process outlined in this section. Step 1: Use Keytool to Create a New Keystore See Tomcat: Create CSR & Install SSL/TLS Certificate with the DigiCert Utility. You can use the DigiCert Utility to generate your CSR and prepare your SSL/TLS certificate file for installation on your Tomcat server. If you are looking for a simpler way to create CSRs, and install and manage your SSL/TLS certificates, we recommend using the DigiCert ® Certificate Utility for Windows. To view these instructions in Spanish, see CSR para Tomcat and Tomcat Instalar Certificado SSL. To install your SSL certificate, see Tomcat Server: Install and Configure Your SSL/TLS Certificate. To create your certificate signing request (CSR), see Tomcat Server: Create Your CSR with Java Keytool. Restart Note: After you've installed your SSL/TLS certificate and configured the server to use it, you must restart the Tomcat service. Use these instructions to generate your certificate signing request (CSR) and install your SSL/TLS certificate on your Tomcat server using Java’s Keytool. Keytool -importkeystore -srckeystore /etc/tomcat8/keystore/12 -srcstoretype pkcs12 -srcstorepass HERETHEPASSWORD -destkeystore /etc/tomcat8/keystore/ -deststoretype jks -deststorepass HERETHEPASSWORDģ.Use Java's Keytool to create a CSR and install your SSL/TLS certificate on your Tomcat (or other Java-based) server ![]() Openssl pkcs12 -export -in /etc/letsencrypt/live//fullchain.pem -inkey /etc/letsencrypt/live//privkey.pem -out /etc/tomcat8/keystore/12 -password pass:HERETHEPASSWORDĢ.- Import pkcs12 store into a keystore (change HERETHEPASSWORD with the password used in previous command): Once you have identified the right cert, you need to recreate the keystore with the new key and cert.Ġ.- Create a dir to store your keystore, I’m using /etc/tomcat8/keystore/ for this example, you should use the path that you want.ġ.- Create a pkcs12 store (change HERETHEPASSWORD with the password you want): Note: even though the intermediates are in the certificate files they are not trusted by the keystore until the intermediate certificate is in the store.Ĭonverting Standard certbot artifacts to a JKS If we run the commands again we will not get warnings as the intermediate is in the keystore. Keytool -import -trustcacerts -alias LE_INTERMEDIATE -file. ![]() We can download the Let’s Encrypt X3 Intermediate and add it to the store using the following command You can say yes to force the keytool to accept the certificate however there is a different ways of also dealing with this error Keytool -importcert -alias san-cert -keystore letsencrypt.jks -storepass test12345 -file. Keytool -importcert -alias simple-cert -keystore letsencrypt.jks -storepass test12345 -file. The key to adding the certs is associating them with the keys
