Coding and Decoding Base64 from the Windows Command Line: A How-To Guide

 To perform base64 encoding and decoding from the command line in Windows, you can utilize the built-in utility called CertUtil. Here's how you can do it:

Base64 Encoding: To encode a file using base64 from the command line, you can use the following command:

CertUtil -encode inputFile outputFile

Replace inputFile with the path to the file you want to encode and outputFile with the desired name for the encoded output file.

For example, if you want to encode a text file named "example.txt" and create an encoded output file named "encoded.txt", you would use the following command:

CertUtil -encode example.txt encoded.txt

 Base64 Decoding:

To decode a base64 encoded file from the command line, you can use this command:

CertUtil -decode inputFile outputFile

Replace inputFile with the path to the base64 encoded file and outputFile with the desired name for the decoded output file.

For instance, if you have an encoded file named "encoded.txt" and want to decode it to create a file named "decoded.txt", you would use the following command:

CertUtil -decode encoded.txt decoded.txt

Remember to use the appropriate file paths and names for your specific use case. This method provides a straightforward way to perform base64 encoding and decoding using the Windows command line utility.
