Library created to be used in my personal website. Annoyed by the amount of spambots that used the contact form on the website I decided to add the captcha verification before the email was actually sent.
The library build a Captcha object from a randomly generated string and provides a convenient method to obtain the image as Base64 string.
The Captcha builder allows the user to apply customizations such as: apply image filters, font transformations and customizations, decide the string length and more.
