Implement an api .net that generates the response of a visualCapctha.
List all text-label solution for the VisualCaptcha
Download all the image database used by VisualCaptcha
Calculate checksum of each PNG downloaded
Making an map with text-label corresponding to the right image's checksum
Automatized with a Python script a call to "/start/1" ("1" to force a minimum number of image choice in the user session, that was 2 images in this old implementation of VisualCaptcha)
Then download each "/image/0" and "/image/1"
Calculate their PNG-checksum and search these values in the "map"
Send the right "value" to the final page (100% captcha bypass)
