Cryptography: How something nerdy went mainstream

Cryptography is one of the fundamental aspects of information security. It is used to encrypt or encode messages so that their content may not be read, modified, or hidden by an unauthorized third party. In this way, it helps information to meet three key requirements to be secured: confidentiality, integrity, and availability.

This method takes place in most of our daily activities. Think, for example, when you send an email – if the email provider did not use encryption techniques, the content might be intercepted and read by unknown people.
