#PYTHON BASE64 DECODE HOW TO#
In this tutorial, you learned how to base64 encode files and strings.Have you ever received a PDF or an image file from someone via email, only to see strange characters when you open it? This can happen if your email server was only designed to handle text data. base64 -decode /path/to/file > output.txt Conclusion You may want to output stdout directly to a file. base64 -decode /path/to/fileĪs with encoding files, the output will be a very long string of the original file. To decode a file with contents that are base64 encoded, you simply provide the path of the file with the -decode flag.
Provided your encoding was not corrupted the output should be your original string. Using the example encoding shown above, let’s decode it back into its original form.
With encoded string, you can pipe an echo command into base64 as you did to encode it. To decode with base64 you need to use the -decode flag. bas64 /path/to/file > output.txt Decoding Strings You may want to write the stdout to file instead. This will output a very long, base64 encoded string. To base64 encode a file base64 /path/to/file Which will output the following bXktc3RyaW5n Without the -n flag you may capture a hidden characters, like line returns or spaces, which will corrupt your base64 encoding. To ensure no extra, hidden characters are added use the -n flag. To base64 encode string you can pipe an echo command into the base64 command-line tool. While it may obfuscate that actual data from should surfers, anyone who has access to base64 encoded data can easily decode it. Rather it is a useful way of transferring or storing large data in the form of a string. Base64 is not EncryptionĮncoding files is not encryption and should never be used to secure sensitive data on disk. In short, base64 encoding ensures the integrity of our data when transferred over the network. The reason is ASCII files are string converted to bytes, and when those bytes are decoded incorrectly back to ASCII your data becomes corrupt.īase64 was introduced as a way to convert your ASCII data into arbitrary bytes, where they could then be transferred as bytes, and decoded correctly back to ASCII. Transferring an ASCII file over the network can cause corruption if not decoded correctly. OSX also comes bundled with its own version of base64. You should not have to perform any additional steps. If you are running popular linux distributions, such as Ubuntu, Debian, CentOS, or Red Hat, the base64 command-line tool is typically pre-installed. How to base64 encode on Ubuntu, Debian, OSX, and Red Hat One being is ensuring data integrity when transferring data over the network, while another is storing Secrets in Kubernetes.Īfter reading this tutorial you will understand how to easily encode files or strings, and then decode them back. You will also learn what base64 encoding is and why it should never be used to protect data from unauthorized access.īase64 encoding and decoding data has many use cases. In this tutorial, you will learn how to base64 encode and decode from the command-line on Linux.
