Java is a prominent and highly prevalent language in which thousands of software are regularly designed. From social media platforms to popular desktop applications, Java is used to build truly great applications. However, to ensure the safety of Java applications from malware, owners need to obtain a Java code signing certificate.
It helps assert the software publisher’s identity to its users and affirm file integrity. The certificate proves that the code has not been modified after being signed by the owner. So through this Java Code Signing Certificate Guide, we will explore different aspects of the Java code signing and the way to purchase it.
Code signing is the process of digitally signing a piece of code and providing a hash value to it, which can be used to determine your identity and ensure software integrity.
A Java Code Signing Certificate is a certificate issued by a trusted certificate authority that ensures the code and its owner is verified. Java code signing certificate can be obtained for Java software, applications, and executables.
To procure a code signing certificate for your apps, your software needs to pass a validation test. Based on the test, the authority issues you the certificate showcasing your software’s genuineness.
Whenever a code is signed, a digital signature is affixed to it. Firstly, hashing is done to encrypt the code. The processed file is again signed and then hashed to ensure double security. The hashes in the code serve as a checksum, ensuring that no two disparate inputs can produce the same hash value.
Even a slight code change code will result in a failed checksum. Further, when the client receives the software, they check the validity of the certificate and signature. The system marks the certificate as trustworthy once it authenticates the certificate.
You get multiple benefits when you buy Java Code Signing Certificate, such as
Your Java code signing certificate consists of a digital signature from the certifying authority that proves your software is authentic. Also, the hashed function used with the digital signature ensures the software code can not be modified without the owner’s permission.
When a user downloads software, the OS usually pops up a security message if the software publisher is verified or not. A verified publisher certainly assures the user that the downloaded software is safe to use.
The Java code signing certificate has all the details related to the publisher’s identity. You can verify the software’s company name, owner name, etc., and become sure to use the software.
The code signing certificate is an essential tool to determine the quality of the code. Having a certificate for software can mean the owner goes through all the required processes to build software. Hence, the probability of code being safe, secure, and reliable is more.
A certificate provided with the software definitely adds a level of confidence to the user. The user does not resist downloading the software and gladly makes use of the software.
A simple Java code signing certificate can significantly amplify your brand reputation. As you provide the users with official documents, they will see more value in your brand and look out for more of your products.
The downloading rate of the software also enhances when you sign your Java application with a code signing certificate. Amidst the increasing rate of cybercrimes, users want to use only trustful software.
The process to buy Java Code Signing Certificate is fairly simple. The following is the process:
Before adding the certificate to your software, make sure to have Java Development Kit (JDK) installed in your computer system. Ensure your JDK bin folder is in the PATH environment (C:\Program Files\Java\jdk1.7.0_02\bin).
The further process is as follows:
The process completes in three basic steps:
1. Build a Certificate KeyStore and Private Key
Open your Run window and type the following command:
keytool -genkey -alias alias_name -keyalg RSA -keystore keystore_name.jks -keysize 2048
You will be asked to enter and confirm the password. Make sure to remember this password, else you will have to repeat all the steps again.
2. Complete the Form
Enter your details in the given form. Make sure to add all the information to the form. The form will ask questions such as
Enter keystore password:
Re-enter new password:
What is your name, first and last?
[User]: Firstname Lastname
What is the name of your organization?
What is your City Name or Locality Name?
What is the name of your State?
What is the two-letter country code for this unit?
Is CN= Firstname Lastname, O=YourCompanyName, L=YourCity, ST=YourState, C=US correct?
Enter key password for <server>
3. Submitting the Request
After all the necessary details are entered correctly, you need to submit the form and a Java KeyStore file (keystore_name.jks) will be created.
To generate a CSR (Certificate Signing Request) for your java code signing, you need to follow the given procedure:
1. CSR Generation using Command Line Interface
Use the CLI to generate your CSR once the Keystore is created. Type in the command:
keytool -certreq -keyalg RSA -alias alias_name -file your_csr_file.csr -keystore keystore_name.jks
This command will generate a private key (.jks file) and a CSR (.csr file). Also create a backup for the file to prevent going through the same process if any installation issues come at later stages.
2. Completion of the Form
Visit the certificate issuing authority and generate a request to buy Java Code Signing Certificate. Some authorities let you upload the CSR file to gather information about you.
3. Installing the Java Code Signing Certificate
After successfully submitting a CSR request, the certificate authority will validate your information and software and issue you a Java Code Signing Certificate that can be obtained via email.
Once you get the code signing certificate, you can install it on your website server using the following command:
keytool -import -trustcacerts -alias alias_name -file CertFile.p7b -keystore keystore_name.jks.
The immensity of a code signing certificate is extremely high compared to its price. A Java code signing certificate usually ranges from $80 to $500 per year, depending upon the type of certificate and brand you choose. You can also look out for schemes to get the certificate at discounted prices.
We hope this Java Code Signing Certificate guide would have helped you understand the code signing process more effectively. A Java Code Signing Certificate is a great way to earn the trust of your customers and ensure software integrity. Therefore, every publisher must obtain the code signing certificate for its software for a secure user experience.
