Cryptography and Network Security for the Internet

Cryptography is the process of making information secret by converting data or text to a coded format to be sent to intended users. The recipient then deciphers the code to obtain the message. The Internet makes sending private messages much more challenging, since anyone with adequate computer skills could potentially tap into a network, intercept a message, and change it or use the information for criminal purposes, which is why effective cryptography is crucial. Using cryptography enables us to prevent our information from getting into the wrong hands, and it is an important aspect of network security.
