Also known as: uuencoding, UUE
The original Unix method for carrying binary data over text-only channels, dating to the late 1970s and used on Usenet for two decades. It maps every three bytes onto four printable ASCII characters, inflating the post by roughly 35%. Sections are marked by begin and end lines. Superseded by yEnc after 2001, though old archived posts and a few text groups still contain uuencoded data.
