Crypto Challenge

Info: Welcome to the first BSidesPhilly Crypto Challenge held on December 8th, 2017. Being the first year we wanted to have something fun and quick during our short day. There is a series of cryptograms which get more difficult and will be needed to decipher the final flag (kite… get it!).
