Vorras Antibot is a program that generates images to stop robot form submission.
So, how does Vorras Antibot work? The program generates a random sequence of alphanumeric characters and a picture in PNG format that displays that sequence. It returns the filename of the picture and the sequence in an encrypted (hashed) format, which then can be stored on your HTML form.
When a user visits your web page and attempts to fill out the form, he or she has to look at the picture and type in the sequence as shown. Once the form is submitted, the sequence the user typed in is encrypted (hashed) and compared to the original sequence. If they match, the user passes the test - otherwise, it is necessary to re-try. Check out the demo on our website to get a better understanding of how Vorras Antibot works.
Vorras Antibot uses pre-existing PNG files to form the character sequence in PNG format. These graphic files of alphanumeric characters come in PNG format and are provided when you download Vorras Antibot. If you want to change the existing PNG files, you can do so by using any graphics package to create png files for all letters and numbers and naming them as a.png, b.png,..., 0.png, 1.png, ... Once done, upload them on your server and place them in the data subdirectory inside the Vorras Antibot directory. Run the parseidat.py script, and the software will generate intermediate-format files that are necessary to run Vorras Antibot. Once you have completed these steps, you can re-run Vorras Antibot with your new graphic files.
All in all, Vorras Antibot is an excellent solution to protect your website from bot activity. For more information, please refer to the README file that accompanies the software.
