Abstract – In this paper we are going to look at various
sensitive data and information in various contexts, including online transactions, personal information storage, and government communications. As technology continues to advance, the importance of cryptography in web security will only increase, making it essential to understand and implement cryptographic techniques effectively.
cryptographic algorithms and their performance. We will discuss about the types of cryptographic algorithms, also the need of cryptography in blockchain and cloud security as they fall under cryptography for web security. We are also going to see the reasons why we need cryptography algorithms and what kind of algorithms are going to be used at what specific task and their resistance from various attacks. We will also take a look at the differences between asymmetric and symmetric cryptography.

1. INTRODUCTION Cryptography has become an integral part of our daily lives in the digital age. With the increasing use of the internet, protecting sensitive data and information has become a top priority for individuals and organizations alike. Cryptographic techniques such as encryption, hashing, and digital signatures have been developed to safeguard our privacy and security online.
The paper [5] proposes a new cryptographic system that allows for secure communication over an insecure channel without requiring the prior exchange of a secret key. The authors introduce the concept of public and private keys, where each user has a public key that can be freely shared, and a private key that is kept secret. They demonstrate how this approach can be used to solve key distribution problems and enable secure communication between parties without needing to share a secret key beforehand. The paper also discusses the potential applications of this new approach to cryptography and its implications for the security of modern communication systems. Overall, the paper is a seminal work that has had a significant impact on the field of cryptography and computer security.
Encryption, for example, is used to ensure the confidentiality of data by converting plaintext into ciphertext, making it unreadable to unauthorized parties. Hashing, on the other hand, is used to ensure the integrity of data by creating a unique fingerprint or hash of the original data that cannot be reversed. Digital signatures provide a means of verifying the authenticity of data by using a private key to sign a message, which can be verified by anyone with the corresponding public key.
In the paper [2] the writers discussed the importance of cryptographic hash functions and their properties for various applications in computer security. The paper defines the concepts of preimage resistance, second-preimage resistance, and collision resistance and explores the implications of each property for different security requirements. It also provides an overview of existing attacks on cryptographic hash functions and discusses the importance of selecting appropriate hash functions for different applications. The paper highlights the need for secure hash functions in various cryptographic protocols and systems, including digital signatures, message authentication codes, and password storage. Overall, the paper emphasises the importance of cryptographic hash functions as a fundamental building block of secure systems and provides a
The importance of cryptography in web security cannot be overstated. Without it, sensitive information would be vulnerable to attacks from cybercriminals, leading to identity theft, financial fraud, and other forms of malicious activity. Cryptography provides a layer of protection that is critical for maintaining privacy and security in the digital age. In addition, cryptography has become a cornerstone of modern communication systems, such as email, messaging apps, and social media platforms. These systems rely on encryption and digital signatures to ensure that messages are secure and authentic. In government and military contexts, cryptography plays a crucial role in safeguarding classified information and national security. The role of cryptography in privacy and security in the digital age cannot be overstated. It is essential for protecting
