But there is something I am failing to understand: for most CAPTCHA(including reCAPTCHA v1) the manually deciphered text is sent directly to the server inside an ʜᴛᴛᴘ header. But with reCAPTCHA v2, the response/ʜᴛᴛᴘ header sent to the server looks like this:
even with an audio to text sample. Whatever the method claimed to be used, I am still failing to understand the link between
g-recaptcha-response HTTP header and human created data.
g-recaptcha-response one time token seems to be a requirement for all bypass methods. So what is the link between the one time token and a deciphered audio text for example since peoples did reverse engineered it ?
The only thing I understood is everything is client side concerning token generation (no server side requests).
