A lot of the everyday applications we\nuse, such as social media platforms, popular desktop applications, and large\nparts of Android, use Java or were built using it. A Java <a href=\"https:\/\/sectigostore.com\/code-signing\">code signing certificate<\/a> helps\nto assert the identity of the software publisher to the end users and affirms\nfile integrity. Essentially, it assures customers that an attacker has not\nmodified the program after it has been signed by the publisher, and that the\npublisher is legitimate.<\/p>\n\n\n\n<p>If you wish to purchase Java code signing certificates, Sectigo has some good options at discounted rates and, what\u2019s more, it comes with a 30-day money back guarantee!  <\/p>\n\n\n\n<p>Let\u2019s dive into the process of buying and installing a Java code signing certificate on your server. <\/p>\n\n\n\n<div class=\"graysection\"><h2>Shop for Java Code Signing Certificates \u2013 Save 53%<\/h2>\n<p><strong>Save 53%<\/strong> on Sectigo Code Signing Certificates.

The keytool utility is distributed with JDK\/JRE and will be used to execute the commands in the following sections. For Windows server, ensure that the JDK bin folder is in the PATH environment (Example \u2013 C:\\Program Files\\Java\\jdk1.7.0_02\\bin) and if you change the directory (CD) to the JDK bin folder, you can use the keytool directly from there.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Creating a Java KeyStore<\/strong><\/h2>\n\n\n\n<p>The steps below will help you to create a KeyStore that will be required during the certificate signing request (CSR) generation as well as while installing the certificate.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">1. Create a Certificate KeyStore and Private Key<\/h3>\n\n\n\n<p>To create both of these items, run the following command:<\/p>\n\n\n\n<p>keytool -genkey -alias alias_name -keyalg RSA -keystore keystore_name.jks -keysize 2048<\/p>\n\n\n\n<p>You\u2019ll be asked to enter and confirm a password. The password and the alias name for the private key will be required later in the process as well. Be sure to remember them else you will need to redo the entire process.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2. Complete the Form Information Fields<\/h3>\n\n\n\n<p>Next, you\u2019ll be prompted to enter further details like first and last name, city, state, etc., similar to the information requested while filling out a CSR for an SSL certificate. <\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\"><p>Enter keystore password:<br> Re-enter new password:<br> What is your first and last name?<br> \u00a0[Unknown]: Firstname Lastname or DomainName<br> What is the name of your organizational unit?<br> \u00a0[Unknown]: DepartmentName<br> What is the name of your organization?<br> \u00a0[Unknown]: CompanyName or Firstname Lastname<br> What is the name of your City or Locality?<br> \u00a0[Unknown]: YourCity<br> What is the name of your State or Province?<br> \u00a0[Unknown]: YourState or YourProvince<br> What is the two-letter country code for this unit?<br> \u00a0[Unknown]: YourCountryCode<br> Is CN= DomainName or Firstname Lastname, OU=YourDepartment, O=YourCompanyName or Firstname Lastname, L=YourCity, ST=YourState, C=US correct?<br> \u00a0[no]: yes<br> Enter key password for &lt;server><br> \u00a0(RETURN if same as keystore password):<\/p><\/blockquote>\n\n\n\n<h3 class=\"wp-block-heading\">3. Confirm Your Submission to Generate Your KeyStore File<\/h3>\n\n\n\n<p>Once the details have been filled in, you can confirm or reject your submission by typing <strong>Yes<\/strong> or <strong>No<\/strong>. After all the details are entered correctly, a Java KeyStore file (keystore_name.jks from the above example) will be created. <\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Generating a CSR<\/strong><\/h2>\n\n\n\n<p>Follow the instructions below to generate a certificate signing request (CSR) for your java code signing certificate.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">1. Generate Your CSR Using the Command Line Interface<\/h3>\n\n\n\n<p>Once the KeyStore is created, you can generate your (CSR) using the command below: <\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\"><p><strong>keytool -certreq -keyalg<\/strong> <strong>RSA -alias <\/strong>alias_name\u00a0<strong>-file<\/strong> your_csr_file<strong>.csr<\/strong> <strong>-keystore<\/strong> keystore_name.<strong>jks<\/strong><\/p><\/blockquote>\n\n\n\n<p>Consider creating a backup of your KeyStore as a safeguard against any installation issues you might run into while importing the certificate into the original file. The above command will create a private key (.jks file) and a CSR (.csr file).<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2. Complete the Required Field<\/h3>\n\n\n\n<p>While purchasing your Java code signing certificate, open the \u201c.csr\u201d file created in the previous step with a text editor (Notepad or Vi) and simply copy and paste the contents of the file into the relevant field in the order form.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Installing the Java Code Signing Certificate on Your Server<\/strong><\/h3>\n\n\n\n<p>Once the CSR request is submitted, the certificate authority (CA) will validate and issue your Java code signing certificate and share it via email. The file should have a \u201c.p7b\u201d extension. If it has a different extension, copy the contents of the cert file, including the headers, without any additional white spaces, line breaks, etc. Use a text editor to paste the contents and save the file with a \u201c.p7b\u201d extension. Alternatively, you can make use of the OpenSSL library to convert your certificate file to the required format. The steps given below describe the process of installing the Java code signing certificate onto your server.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">1. Install Your Java Code Signing Certificate<\/h3>\n\n\n\n<p>To install the certificate on the server, execute\nthe following command:<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\"><p><strong>keytool -import<\/strong> <strong>-trustcacerts<\/strong> <strong>-alias<\/strong> alias_name <strong>-file<\/strong> CertFile.<strong>p7b<\/strong> <strong>-keystore<\/strong> keystore_name.<strong>jks<\/strong> <\/p><\/blockquote>\n\n\n\n<p><em>Note: You will be required to enter the\npassword for theKkeyStore. If you\u2019re asked to trust the certificate, type <strong>Y<\/strong>\nor <strong>Yes<\/strong> as prompted.<\/em><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2. Use Your Code Signing Certificate to Sign Your Java Code<\/h3>\n\n\n\n<p>If the installation is successful, you\nwill receive a message saying, \u201cCertificate reply was installed in KeyStore.\u201d <\/p>\n\n\n\n<p>Once your code signing\ncertificate is installed and configured into your KeyStore, you\u2019ll be able to\nsign your Java code.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Java is one of the most popular languages used by developers to build software.
