How would you use a cipher command?

A cipher command is typically used to encrypt or decrypt data to ensure its confidentiality. To use it, you would specify the command along with the desired encryption algorithm, the input file or text, and any necessary keys or parameters. For example, in a command-line interface, you might run a command like cipher /e filename.txt to encrypt a file named "filename.txt." Ensure you have the appropriate permissions and understand the encryption method being used for effective implementation.
