Challenge #1
<SdK> gibts wörter, die nach rot13 n anderes existierendes wort ergeben?
Testdatei: http://qu.cx/~mxf/web2.gz == /usr/share/dict/web2 Gepiped durch wc -l sollte 154 rausfallen, da einige Wörter doppelt vorkommen. Falls Duplikate gefiltert werden, sollten es 132 sein. Ausgabe in Form von "iraq->vend\n"

CentronX: eicar & ein Inder
Man lasse einen Inder das ganze in eicar eintippen und dann vergleichen.
