CryptoBook is a community project, developed by members of CryptoHack to create a resource for people to learn cryptography. The focus of this project is to create a friendly resource for the mathematical fundamentals of cryptography, along with corresponding SageMath implementation.
Think of this as an alternative SageMath documentation source, where the focus is its application in solving cryptographic problems.
