 ## Motivation
-Help CTF players and individuals interested in the field of Cryptography provide a platform for learning attacks in crypto and =for experienced CTF players to practice challenges systematically divided into attacks associated with different sub-domains in crypto. Also, illustrate through various attack explanations how proper implementation of protocols is crucial.
