Base64 encoding converts groups of 3 bytes (24 bits) from binary data into 4 characters from a set of 64 predefined characters, which usually include uppercase letters, lowercase letters, digits, and a few special characters. When the length of binary data is not divisible by 3, padding characters, often represented by the symbol ‘=’, are added to the encoded output. This ensures that the total number of characters is a multiple of 4.

From the Linux command line interface, execute the below commands to encode or decode string values.

Encoding

echo -n 'tekspace' | base64

Output:

dGVrc3BhY2U=

Decoding

echo -n dGVrc3BhY2U= | base64 -d

Output:

tekspace

In this tutorial, I will show you how to convert a certificate from .pfx to base64.

Open PowerShell as an administrator.

Now that we have a PowerShell console opened. Let’s first load the content into a variable.

$pfx_cert = get-content 'c:\certificate.pfx' -Encoding Byte

The above command will load the content with byte encoding. If you print $pfx_cert in the PowerShell console, you will see random numbers. In order to convert to base64 format, we will use system namespace from Windows system.

To convert a certificate in base64, execute the below command.

$base64 = [System.Convert]::ToBase64String($pfx_cert)

The above command will save it in $base64 variable, and now you can use this variable or output it to a file depending on your scenario.
