Cryptography can be used for many purposes, but there are two types of cryptographic algorithms you need to understand: symmetric and asymmetric. Learn more from the experts at Global Knowledge.

Consider how many financial transactions are performed on the Internet everyday. Protecting all this data is of upmost importance. Cryptography can be defined as the process of concealing the contents of a message from all except those who know the key. Cryptography can be used for many purposes, but there are two types of cryptographic algorithms you need to understand, symmetric and asymmetric. Symmetric uses a single key, whereas asymmetric uses two keys. What else is required to have a good understanding of cryptography? It’s important to start with an understanding of how cryptography relates to the basic foundations of security: authentication, integrity, confidentiality, and non-repudiation.
