blogging on Base16b » Code Sample http://www.base16b.org/blog Efficient, standards-compliant binary encoding Sat, 22 Aug 2009 01:57:14 +0000 en hourly 1 http://wordpress.org/?v=3.0 Playing with Base16b http://www.base16b.org/blog/2009/08/playing-with-base16b/ http://www.base16b.org/blog/2009/08/playing-with-base16b/#comments Thu, 06 Aug 2009 10:04:13 +0000 henchan http://www.base16b.org/blog/?p=93 The previous post showed base64 encoding of part of a WordPress post. Base64 encoded 148 characters (a few of which were due to htmlentity expansion).

Now let’s do the same thing using a version of the plugin modified for Base16b encoding.
After hitting Encode, if you see only empty boxes, you might want to install a font such as LastResort.

This plug-in is now available from the WordPress Plugin site.

This original script comes from MrAndersonMD

Note: the image tag comprising a URL of 84 characters (not the actual binary image) is encoded. See the next post for the encoded img tag.
Note2: the original text is additionally altered when encoded, through htmlentity substitution. e.g double quote ” is encoded in base64 as & quot; (no space)

    Base64 = 148 characters

Pressing Decode reveals the URL and the page subsequently displays the linked resource.

See the next post for equivalent encoding in Base16b.
