Discuss how cryptology is used on the internet for e-business or e-commerce. provide examples and types of cryptographic tools and techniques

E-commerce deals with a wide range of products and services on the internet. Therefore, it is crucial to recognize security and a high degree of confidence required in the authenticity and privacy of online transactions. Sometimes, it can be challenging to trust the internet where these kinds of transactions are made; thus, the need for cryptography. Cryptography provides data security and reduces the risk of cybercrimes, such as hacking and phishing.

Modern Cryptography services can be seen as data authentication, user authentication, data confidentiality, and no-repudiation of origin. The most common type of cryptographic tools and techniques is the use of the RSA Algorithm. It is used for securing communications between web browsers and e-commerce sites. The interactions make use of an SSL certificate, which is based on public and private keys. PKI (Public-Key Infrastructure) is also another excellent example of cryptographic tools and techniques. Based on several things, PKI is used to identify or authenticate the identity of the other party on the internet.
