Securing Data with Cryptography: An Introduction

Cryptography is the practice and study of techniques for secure communication in the presence of third parties. It is used to protect confidential information and to ensure its authenticity and integrity. Cryptography involves the use of mathematical algorithms, protocols, and techniques to protect data from unauthorized access, modification, and disclosure. It is also used to protect data from being read or intercepted by an unintended recipient. Cryptography includes both symmetric and asymmetric encryption, digital signatures, and public-key infrastructure. Cryptography is used to protect data in transit, at rest, and in storage. It is also used to protect data from being tampered with or manipulated. Cryptography is used in various applications, such as banking, military, and government communications, to ensure the confidentiality, integrity, and authenticity of information.
