Encoding Torn Apart By Ankit Fadia <a

<p class=MsoNormal><font size="2" face="Arial, Helvetica, sans-serif">Since
its introduction, Base64 encoding has extremely quickly gained popularity.
Besides being the default Encoding standard being used for encoding files
to be sent as attachments by <font color="#FFFFFF"><b>Multipurpose Internet
Mail Extensions or MIME</b></font>, it has also started being used in a number
of other places.</font></p>
<p class=MsoNormal><font size="2" face="Arial, Helvetica, sans-serif"><![if !supportEmptyParas]> <![endif]><o:p></o:p></font></p>
<p class=MsoNormal><font size="2" face="Arial, Helvetica, sans-serif">Please
note that almost all email clients use MIME to send files as attachments,
this in turn means that a majority of email clients are using Base64 to encode
files, before being sent across networks. </font></p>

<p class=MsoNormal><font size="2" face="Arial, Helvetica, sans-serif">Another
popular usage of Base64 encoding is in the case of Web Servers implementing
HTTP Based Basic Authentication. When the server wants to restrict or control
the access to certain folders, then, it can password protect them by using
HTTP Based Basic Authentication.<span
