Overview of Certificate Formats
Before we delve into the technical details of converting PFX certificates to PEM format, let’s first understand what these formats are and why they are important.
What is a PFX Certificate?
A PFX (Personal Information Exchange) certificate is a digital certificate that contains both a public key and a private key. It is typically used for secure communication over the internet and is commonly used in Microsoft Windows environments.
What is a PEM Certificate?
PEM (Privacy Enhanced Mail) is a Base64-encoded format for digital certificates that is commonly used in UNIX-based environments. It contains only the public key and is used for secure communication between servers and clients.
Why Convert PFX to PEM?
There are several reasons why you might want to convert a PFX certificate to PEM format. For example, if you want to use a PFX certificate with a server or application that only supports PEM format, you will need to convert the PFX certificate to PEM format.
Another reason to convert PFX to PEM is that PEM certificates are easier to work with than PFX certificates. PEM certificates are text-based, which means you can view and edit them using a text editor. PFX certificates, on the other hand, are binary files, which makes them difficult to work with.
One key takeaway from this text is that converting a PFX certificate to PEM format is important if you need to use a PFX certificate with a server or application that only supports PEM format, and PEM certificates are easier to work with than PFX certificates.
Prerequisites
Before we get started, you will need the following:
- OpenSSL installed on your system
- The PFX certificate you want to convert
- The password for the PFX certificate
Steps to Convert PFX to PEM
The process of converting a PFX certificate to PEM format is relatively straightforward. Here are the steps:
Step 1: Convert the PFX Certificate to PEM Format
To convert the PFX certificate to PEM format, you will need to use the OpenSSL command-line tool. Here’s the command you need to use:
“`
In this command, replace cert.pfx with the name of your PFX certificate file and cert.pem with the name of the PEM certificate file you want to create.
Step 2: Enter the Password
When you run the command, OpenSSL will prompt you for the password for the PFX certificate. Enter the password and press Enter.
Step 3: Verify the PEM Certificate
Once the command has completed successfully, you can verify the PEM certificate by opening it in a text editor. The PEM certificate should start with -----BEGIN CERTIFICATE----- and end with -----END CERTIFICATE-----.

FAQs for How to Convert PFX Certificate to PEM
A PFX certificate is a file format used to store a private key and public key pair, as well as the corresponding digital certificate. This file format is often used for online transactions and secure communication over the internet.
A PEM certificate is a file format used to store a public key and digital certificate typically used in web servers and applications. This file format is ASCII encoded and contains header and footer lines that help to identify and validate the certificate.
Why do I need to convert a PFX certificate to PEM?
There are various reasons why you might want to convert a PFX certificate to PEM format. One common reason is if you are using a web server or application that requires PEM format for authentication. Additionally, PEM format is more widely supported than PFX format.
How can I convert a PFX certificate to PEM format?
To convert a PFX certificate to PEM format, you can use the OpenSSL tool. First, open a command prompt and navigate to the folder where your PFX file is stored. Then, enter the following command: openssl pkcs12 -in yourPFXfile.pfx -out yourPEMfile.pem -nodes. This will create a PEM file in the same folder as your PFX file.
What do the OpenSSL command options mean?
The ‘pkcs12’ option tells OpenSSL that you are working with a PFX file. The ‘in’ option specifies the name of the PFX file you want to convert. The ‘out’ option specifies the name of the PEM file you want to create. The ‘-nodes’ option tells OpenSSL that you do not want to include a private key password.
Can I add a password to my PEM file?
Yes, you can add a password to your PEM file by removing the ‘-nodes’ option from the command and including the ‘-des3’ option. This will prompt you to enter a password that will be used to protect the private key in the PEM file.
Will my PFX file be deleted after conversion?
No, your PFX file will remain on your computer after the conversion. You can choose to delete it if you no longer need it, but it is recommended to keep a backup copy of important files like digital certificates.
