Secure Communication Protocols : SSL/TLS, IPsec, and PGP Secure communication protocols are essential for protecting data in transit and ensuring the confidentiality, integrity, and authenticity of online communications. In this article, we'll explore three widely used secure communication protocols: SSL/TLS, IPsec, and PGP. SSL/TLS SSL/TLS (Secure Sockets Layer/Transport Layer Security) is a cryptographic protocol used to secure online communications between a web browser and a web server. SSL/TLS provides: 1. *Encryption*: SSL/TLS encrypts data in transit, protecting it from eavesdropping and interception. 2. *Authentication*: SSL/TLS authenticates the identity of the web server, ensuring that users are communicating with the intended party. IPsec IPsec (Internet Protocol Security) is a suite of protocols used to secure IP communications. IPsec provides: 1. *Encryption*: IPsec encrypts IP packets, protecting them from eavesdropping and interception. 2. *Authentication*: IPsec aut...

Cryptography in Real-World Applications Cryptography is used in various industries to protect sensitive data and ensure the security of online transactions. Let's explore some real-world applications of cryptography: Finance 1. *Secure online transactions*: Cryptography is used to secure online payment systems, such as credit card transactions and online banking. 2. *Digital signatures*: Cryptography is used to create digital signatures, which authenticate the identity of parties involved in financial transactions. Healthcare 1. *Protecting patient data*: Cryptography is used to protect sensitive patient data, such as medical records and personal identifiable information. 2. *Secure communication*: Cryptography is used to secure communication between healthcare providers, patients, and insurance companies. Government 1. *Secure communication*: Cryptography is used to secure communication between government agencies, protecting sensitive information and ensuring national security. 2...
