Enhancing Data Security: A Comprehensive Study on the Efficacy of JSON Web Token (JWT) and HMAC SHA-256 Algorithm for Web Application Security

Abstract

In today's digital era, data security is a very important aspect in various applications and services. In order to protect the integrity, confidentiality and authentication of data, security technologies such as JSON Web Token (JWT) and HMAC SHA256 algorithm are widely used. JWT is an open standard (RFC 7519) that is used to represent information in the form of tokens that can be signed digitally. The research methodology used in this research is a descriptive research method. The descriptive method is a method that describes the purpose of the data collected and records every aspect of the situation being investigated to get a clear picture of what is needed. It was found that there were several data leaks when data security was not implemented in layers, including cases that had occurred such as loss of important data contained in the website and leaks of important data which caused identities to be spread widely. Conclusions from the use of JSON Web Token (JWT) and HMAC-SHA-256 algorithm for website security is that this combination provides a strong layer of protection against security threats that are common in the online environment.
