EscapeQuizz: Check an answer with a QR code

Usage

Question designing

1. Encode the correct answer with Base32 scheme on a Web app or a Unix-like shell , e.g.:

   echo -n "42|Forty two" | base32
   

   When multiple solutions are possible, a | ("pipe") must be used between them.

2. Concatenate the service endpoint and the encoded answer, e.g.:

   http://localhost:5173/GQZHYRTPOJ2HSIDUO5XQ====
   

3. Open the HTTP-URI in a browser. You get a warning if the answer was not coded properly.

4. Convert the HTTP-URI into a QR code and paste it next to the quizz question, e.g.:

   What is the ultimate answer to Life, the Universe and Everything?
