Captcha Breaker

This howto will take you through using Captcha Breaker to break a given captcha. This howto covers only how to use the solvers once you already have image files. This howto does NOT cover how to extract that file from a website, nor how to enter the text back.

At the end, you will pass your image file to the breaker and the last line of output will be the text (with *'s for unrecognized characters):
