  The Role of Cryptography in Secure Online Transactions Cryptography plays a vital role in securing online transactions by protecting sensitive data and ensuring the integrity and authenticity of transactions. Here's how cryptography contributes to secure online transactions: Secure Data Transmission 1. *Encryption*: Cryptography encrypts data in transit, making it unreadable to unauthorized parties. 2. *Secure Sockets Layer/Transport Layer Security (SSL/TLS)*: SSL/TLS protocols use cryptography to establish secure connections between clients and servers. Authentication and Verification 1. *Digital Signatures*: Cryptography-based digital signatures authenticate the sender's identity and ensure the integrity of transactions. 2. *Certificates*: Digital certificates, issued by trusted Certificate Authorities (CAs), verify the identity of parties involved in transactions. Data Integrity 1. *Hash Functions*: Cryptography-based hash functions ensure data integrity by detecting any t...
