cryptography | access control (linux flag hunt) | binary exploit -- 3

3 tasks, the DL is on the 18th of April at 21 CEST - `task1`: cryptography - `task2`: access control (linux flag hunt) - `task3`: binary exploit Each task challenges you to find a "flag", a string with the form `SpeishFlag{<random hash>}` generated for your user. There is a single flag per task: if you got one with the appropriate syntax, it will be accepted as the correct solution (please take care when decoding or manually copying it, e.g. zero vs 'o').
