How to Export Code Signing PFX Certificate with the DigiCert Utility Tool

Export Code Signing PFX Certificate with the DigiCert Utility Tool

Code signing means putting a digital signature on executables and scripts as proof from the software author or developer that the code has not been subjected to tampering or altering since it was signed. A code-signing certificate is a digital certificate that contains information about the identity of the certificate owner and a public key that is used to verify the authenticity of the code-signing process.

Code signing is used to provide security and trust in software distribution. When users install software that has been signed with a valid code signing certificate, they can be sure that the software comes from a trusted source and has not been tampered with. Code signing also helps to prevent malware from being distributed under the guise of legitimate software.

Many software owners or developers are intimidated by key-pair. But the truth is that key pairs or certificates are quite convenient and simple to understand. Code Signing Certificates, unlike SSL certificates, are responsible for signing codes and developing a tamper-proof digital shrink wrap of executable files and showing the software publisher’s or owner’s authenticity to one who downloads or installs the software.

Windows servers use .pfx files containing the SSL certificate file and the associated private key file. DigiCert offers the public key file, after which the server can be used for generating the associated private key file. This will be done as a part of the CSR.

For the functioning of the Code Signing Certificate, it is ideal to possess both the public and private keys. So, if you need to transfer your SSL certificates from one server to another, export them as a .pfx file.

Many Certificate Authorities differentiate their Code Signing Products and have different ways of enrolling and installing them. However, the DigiCert Certificate Utility is cross-platform, which means one can sign the following list of files with the same certificate.

  • .exe
  • .cab
  • .dll
  • .ocx
  • .msi
  • .xpi
  • .xap
  • Windows kernel-mode
  • Java. jre
  • Adobe Air.

The DigiCert Utility is a tool that efficiently manages and installs SSL/TLS certificates. With DigiCert Utility, you can view, install, and export your SSL/TLS certificates, as well as manage your account and certificate orders. The utility is available as a standalone application that you can download and install on your computer, or it can be accessed online through the DigiCert website.

What is Code Signing PFX Certificate?

A Code Signing PFX Certificate is a digital certificate that is used to sign software and other types of digital content. It helps to ensure the integrity and authenticity of the content, as well as to protect it from tampering. Typically, it is stored in a Personal Information Exchange (PFX) file, which is a format that is used to store digital certificates and private keys. The PFX file is encrypted and requires a password to be accessed.

When you import a PFX file, you will be prompted to enter the password to unlock the certificate and private key.

PFX files can be created and managed using a variety of tools, including Microsoft’s Certificate Manager and OpenSSL. They can be used to sign a variety of different types of software, including executables, drivers, and other types of code.

Overall, PFX files are a useful tool for managing code signing certificates and ensuring that they can be used on different systems as needed.

Now let us talk about exporting Code Signing PFX Certificate with the DigiCert Utility tool.

Summarizing

Once you have completed the export process using DigiCert Utility, your code signing certificate should be saved as a PFX file in the destination directory that you specified. The PFX file will contain both your code signing certificate and the associated private key, and it will be protected with the password that you specified.

You can then use the PFX file to import your code signing certificate and private key onto another system or use it with a code signing tool. For example, you might use the PFX file to sign an executable file or a driver that you are distributing to end users. It is important to keep your PFX file, and the password that protects it secure, as anyone who has access to the file will be able to use your code signing certificate to sign software. If you need to share your code signing certificate with others, you can do so by exporting a “public only” version of the certificate, which does not include the private key. This can be done using DigiCert Utility or other tools.
