According to Wikipedia, cryptography (from Greek κρυπτός kryptós, “hidden, secret” and γράφειν graphein, “writing”) is the practice and study of techniques for secure communication in the presence of third parties called adversaries.

In cryptography, a cipher is an algorithm for performing encryption or decryption. The fascinating story of cryptography requires us to understand two very old ideas related to number theory and probability theory. Students majoring in Computer Science is very likely to have this subject in their curriculum.

I watched Finding Soul last weekend and the drama planted the seeds of cryptography interest into my mind. Then a close friend of mine introduced to me The Mystery of Gravity Falls, a Disney TV Series in which viewers have to decode all the cryptograms hidden in the credits and inside the journals themselves. Having all these signals from universe (or it’s just my imagination), I decide to start a journey into Cryptography this September. Guess my friends are going to receive strange text messages from me very soon (⌒∇⌒)
