ASCII ART CAPTCHA
    ASCII Art CAPTCHA is a light weight ASCII CAPTCHA generation framework for web sites. It provides useful custom tags which can be integrated with ease. It also supports custom ASCII fonts. It allows the user define fonts with replaceable characters. It provides two CAPATCHA generation strategies. The first one is dictionary based and the other is random word generation. Just import the tag library and include the custom tag shown below,

<%@ taglib uri="http://www.bethecoder.com/tags/captcha/asciiart prefix="btcac" %>
<btcac:asciiCaptcha id="one" fontName="melborn" type="dictionary" />
