​
Input

  • input: The original input text or data
  • output: The string to validate as base64
  • expectedOutput: The expected output to compare against.
  • Any of the input variables (input, output, expectedOutput) can be marked as optional.
  • The returned value from the validate function can be a boolean, string, or a number.

​
Output

  • Result: Boolean (true or false) | string | number

​
Interpretation

Assuming this evaluator returns a boolean
  • true: The string is valid base64
  • false: The string is not valid base64
This evaluator requires a function named validate.

​
Example

import base64

def validate(input, output, expectedOutput):
    try:
        base64.b64decode(str(output), validate=True)
        return True
    except Exception:
        return False
