|
||
Caesar-cypher encryption that replaces each English letter with the one 13
|
||
places forward or back along the alphabet, so that “<span class="quote">The butler did
|
||
it!</span>” becomes “<span class="quote">Gur ohgyre qvq vg!</span>” Most Usenet news
|
||
reading and posting programs include a rot13 feature. It is used to
|
||
enclose the text in a sealed wrapper that the reader must choose to open
|
||
— e.g., for posting things that might offend some readers, or
|
||
<a href="../S/spoiler.html"><i class="glossterm">spoiler</i></a>s. A major advantage of rot13 over
|
||
rot(<tt class="literal">N</tt>) for other <tt class="literal">N</tt> is that it is
|
||
self-inverse, so the same code can be used for encoding and decoding. See
|
||
also <a href="../S/spoiler-space.html"><i class="glossterm">spoiler space</i></a>, which has partly displaced rot13
|
||
since non-Unix-based newsreaders became common.</p></dd><div class="navfooter"><hr/><table width="100%" summary="Navigation footer"><tr><td width="40%" align="left"><a accesskey="p" href="rootkit.html">Prev</a> </td><td width="20%" align="center"><a accesskey="u" href="../R.html">Up</a></td><td width="40%" align="right"> <a accesskey="n" href="rotary-debugger.html">Next</a></td></tr><tr><td width="40%" align="left" valign="top">rootkit </td><td width="20%" align="center"><a accesskey="h" href="../index.html">Home</a></td><td width="40%" align="right" valign="top"> rotary debugger</td></tr></table></div></body></html>
