Cryptography is the study and practice of keeping information secret. It is used in information security to maintain the confidentiality and integrity of data as well as to enable non-repudiation. It allows for secure communication of information from unauthorized parties. In our look at cryptography, we will be examining encryption and cryptographic hash functions, which are tools that can be used to secure data.
