Base64 conversion tool

This tool http://www.infowares.com/base64.php will allow you to decode base64 encoded content, such as the body of certain email messages (mostly spam), and most email attachments. Base64 encoding is also used for a number of other purposes, mostly when data needs to be transmitted over a link or stored on a media that is not 8-bit clean. Feel free to link directly to the base64 tool from your site if you wish. Source code is available at http://www.infowares.com/base64.phps.
