The longer lines are where validation steps were performed.
That was obtained simply by pasting it into https://www.base64decode.org/
You can also use Python on your local system or in a notebook to work on a downloaded file. Hereâs a script to decode a hard-coded file name:
import base64
def decode_base64_file(input_filename, output_filename):
"""Decodes a base64-encoded file and saves the output to a new file.
Args:
input_filename: The path to the input file containing base64 data.
output_filename: The path to the output file where decoded text will be saved.
"""
try:
with open(input_filename, 'r') as f_in:
encoded_data = f_in.read()
except FileNotFoundError:
print(f"Error: Input file '{input_filename}' not found.")
return
except Exception as e:
print(f"Error reading input file: {e}")
return
try:
decoded_data = base64.b64decode(encoded_data).decode('utf-8')
except base64.binascii.Error:
print("Error: Invalid base64 data in the input file.")
return
except Exception as e:
print(f"Error decoding base64 data: {e}")
return
try:
with open(output_filename, 'w') as f_out:
f_out.write(decoded_data)
print(f"Successfully decoded and saved to '{output_filename}'.")
except Exception as e:
print(f"Error writing to output file: {e}")
if __name__ == "__main__":
input_file = "results.txt"
output_file = "results-output.txt"
decode_base64_file(input_file, output_file)
Explanation:
- Import
base64: Imports the necessary library for base64 encoding/decoding.
decode_base64_file function:
- Takes
input_filename and output_filename as arguments.
- File Reading (with error handling):
- Uses a
try-except block to handle potential FileNotFoundError if the input file doesnât exist.
- Uses another
except block to catch any other errors during file reading.
- Reads the entire content of the input file into
encoded_data.
- Base64 Decoding (with error handling):
- Uses a
try-except block to handle base64.binascii.Error which is raised if the data is not valid base64.
- Uses another
except block to catch any other decoding errors.
base64.b64decode(encoded_data) decodes the base64 string..decode('utf-8') converts the decoded bytes to a UTF-8 string (assuming the original text was UTF-8 encoded).
- File Writing (with error handling):
- Uses a
try-except block to handle potential errors during writing to the output file.
- Writes the
decoded_data to the output file.
- Prints a success message.
if __name__ == "__main__": block:
- Ensures the code inside this block is executed only when the script is run directly (not imported as a module).
- Sets the input and output filenames.
- Calls the
decode_base64_file function to perform the decoding.
