# morset (Misc, 50pts, 86 solves)	A mysterious signal… can you decode it? 	Running at morset.pwning.xxx:11821
In this task we were told to conenct to certain server. The server sent us somedots and dashes, so we immediately thought it could be Morse code. Decoding it, though,gave us some gibberish alfanumeric string. They were generally very different, butsometimes they were pretty similar. For example:```AIDQJB34I3OA5B0BVLPE3OGV6XX23TTIGE6I451CC6V0VPWVWWGL1123EL2K56OS6R3W123WF2B0P90XH6NAIDQJB34I3OA5B0BVLPE3OGV6XX23TTIGE6I451CC6V0VPWVWWGL1123EL2K56OS6R41GDX88YQMO172Z3Z```We thought it could be some constant start of the message followed by some challenge.
Finally, we came up with an idea how to decode this text - since this was neither base64nor base32, it could be base36! Used alphabet was `0-9A-Z`.Final decoding and encoding code is in `doit.py` - it turns outserver was sending us questions such as "What is SHA256(grapefruit1234)?". After sendinganswer in the same format, we got the flag.
