The crypto group (CLUB) of the System Security and Cryptography Lab, at Università degli Studi di Milano, in collaboration with De Componendis Cifris (Associazione italiana di Crittografia) and Clusit (The Italian Association for Computer Security), organized the "Cryptowars 2019". This contest aims to raise awareness of the fact that cryptographic algorithms get old and they should be continuously tested, maintained, improved. The event was a week long (21/10 - 27/10) and it had 30 challenges, at the end of the contest we managed to complete 8. We are proud of the result and most importantly this challenge raised our knowledge and awareness on many aspects of cryptography which is going to be very useful for our next CTFs.
