I invented a novel encryption technique that hides a message in the below text box.

Hint about the message (in order to be less broad): After the necessary decryption the message on your monitor can be seen from 10 metres.

  • $\begingroup$ @Reticality indeed I am not sure if it really is lateral thinking, in your opinion should I delete that tag? $\endgroup$ – Caridorc Mar 26 '15 at 21:06
  • $\begingroup$ @ca If the task is just string manipulation, then the tag does not seem to fit. $\endgroup$ – user10203 Mar 26 '15 at 21:12

    $\begingroup$ I feel like this is too broad. You should tell us more about the message and/or the encryption technique. You don't have to (and shouldn't) spell it out for us, but as it is there's no way for someone to know for sure that they got it right. $\endgroup$ – Rob Watts Mar 26 '15 at 21:18

    $\begingroup$ @Caridorc That is indeed an intriguing hint! $\endgroup$ – Rob Watts Mar 26 '15 at 21:22

The solution is:

GOOD

This is obtained by:

Converting all the non-vowels into dots, and looking at the resulting block of text.

Which gives:

......iea.......aiuooi....eioaou....iuoue.......
.....u..........i....e....e....i....e....i......
....u...........u....u....a....a....i.....a.....
...a....ueei....i....u....u....i....e......e....
....a......o....i....o....u....e....e.....e.....
.....o.....e....i....u....a....e....u....u......
......aaeeui....uueiau....uuuauu....aeaui.......

The vowels encode the message as a picture. Here they are all blacked out:

    $\begingroup$ I'm sorry, I can't get the preformat text to work inside a spoiler, which ruins the puzzle for everyone else from 10 meters away... $\endgroup$ – brendan Mar 26 '15 at 22:04

    $\begingroup$ Fixed the formatting. The trick is to use <code> tags and <br> instead of newlines. It's weird, I know. $\endgroup$ – Tryth Mar 26 '15 at 22:06
  • $\begingroup$ You should use the <pre> tag if it's not code. $\endgroup$ – BlueRaja - Danny Pflughoeft Mar 26 '15 at 23:37
  • $\begingroup$ @BlueRaja-DannyPflughoeft Unfortunately <pre> tags do not render properly in spoiler blocks $\endgroup$ – Tryth Mar 27 '15 at 5:14
