Phishing Email Decoding Tools

atob() obfuscation

This p5.js script is designed to find and decode base64-encoded strings that are nested within one another. The script has several functions that work together to achieve this goal:

isBase64(str): This function checks if a given string str is a valid base64-encoded string. It uses a regular expression to test the string and the atob() function to try decoding the string. If the decoding is successful, the function returns true; otherwise, it returns false.
