Proof of Concept for Hetzner's "Heray" PoW Captcha

This is a proof of concept (PoC) for Hetzner's "Heray" Proof of Work (PoW) Captcha. Please note that this is neither functional nor the original code. It simply demonstrates how the system could work based on observed patterns and assumptions.

Overview

Hetzner's "Heray" PoW Captcha likely requires the client to solve a computational puzzle as a form of CAPTCHA, where a specific condition must be met for the challenge to be accepted. The solution involves generating a specific mainbytes value based on given uuid and hsum values.

EmailValidator Class

The ScEmailValidator class provides a static method for validating email addresses using a regular expression.

The regular expression used by this class is based on the pattern defined in RFC 2822 for email addresses. The regular expression is designed to match a wide range of valid email addresses, including email addresses with domain names that contain IP addresses, internationalized domain names (IDNs), and new top-level domain names. The regular expression also supports email addresses with local parts that contain special characters, such as periods, plus signs, and quoted strings.
