How to use Base64 Decode File tool? Decoding any base64 encoded code is very easy. The very reason why Base64 encoding is used is because using Base64 it is possible to encode binary data to ASCII string format. "Hello World" FilePath: The native file path. ROT-13 This will decode ROT-13 encoded text. To decode with base64 you need to use the --decode flag. Therefore, applying different encoding for a file appeared frequently and I guess that most of the fresh developers encounter this situation and ignore the weird characters in a file due to different encoding strategy. ) may be substituted.
