The Base64-encoded certificate structure is commonly referred to as the Privacy Enhanced Mail (PEM) format, but a certificate is fundamentally binary data. If you have worked with the OpenSSL tool, you have seen several examples of Base64-encoded certificates.

One of the most common use cases is certificate encoding.

Knowing how to recognize, encode, and decode Base64 is valuable due to its prevalence as an encoding approach. Using Base64 encoding may seem esoteric, but there are many common scenarios where you will encounter Base64 in systems administration.

This can be done by looking up the values in an ASCII-to-binary conversion table. The first step in the encoding process is to obtain the binary representation of each ASCII character. For example, consider the sentence Hi , where the represents a newline. This allows you to transport binary over protocols or mediums that cannot handle binary data formats and require simple text.īase64 uses 6-bit characters grouped into 24-bit sequences. How Base64 worksįundamentally, Base64 is used to encode binary data as printable text. Finally, I provide some practical examples of Base64 encoding that you will likely encounter as a sysadmin.

Once I explain this simple encoding format, I will introduce the base64 command-line utility that you can use to encode and decode data.

This article walks you through the theoretical aspects of Base64 encoding. It also enables you to use Base64 encoding in your own applications and scripts. Red Hat OpenShift Service on AWS security FAQĭespite Base64's ubiquity, many systems administrators have limited knowledge of how this encoding format actually works. Understanding Base64 can help you better comprehend how data is stored and used by the tools you rely on and support.
