Since a while, crypto stuff in Shadowlamb challs was broken. (thx sysfail for the report)
The reason was a secret that had the wrong length (only 10 chars)
I fixed all those crypto bits and increased the strength of the secret key, as a user once cracked it.
Beside the fixes i wrote a discord connector for the bot.
