A Commitment Scheme library for Coin Flipping/Tossing algorithms and sort

This project implements Commitment Schemes using the Galois/Counter Mode (GCM) of secret-key encryption. Because this AES encryption mode provides both Message Confidentiality and Integrity, it fits perfectly the Hiding and Binding properties of Commitment Schemes. Confidentiality protects the message against passive attacks while integrity protects it from active attacks. GCM, so, works as an Authenticated Encryption where it roughly works as an encryption algorithm with MAC signatures on cipher data.
