Cryptography: An Overview
Cryptography is a branch of mathematics that is used to protect information. It is used in a variety of applications, such as secure communication, authentication, and digital signatures. In this blog post, we will explore the fundamentals of cryptography and how it is used in the world today.
Encryption: The Basics
Encryption is the process of transforming information into a form that is unreadable to anyone without the correct key. This process is used to protect confidential data, such as passwords and financial information, from being accessed by unauthorized individuals. We will look at the different types of encryption and how they work.
Hashing: Keeping Data Secure
Hashing is a technique used to verify the integrity of a piece of data. It is used to ensure that the data has not been modified or tampered with. We will explore how hashing works and the various algorithms used for hashing.
Public Key Cryptography: Keeping Data Secure
Public key cryptography is a form of encryption that uses two keys: a public key and a private key. The public key is used to encrypt the data, while the private key is used to decrypt it. We will discuss the different types of public key cryptography and how they are used to secure data.
Digital Signatures: Authenticating Data
Digital signatures are used to authenticate data and to ensure that it has not been modified. We will look at how digital signatures work and how they are used to verify the integrity of a message.
Cryptography in the Real World
Cryptography is used in a variety of applications in the real world. We will explore how cryptography is used to protect data, authenticate transactions, and secure communication.
In this blog post, we have discussed the fundamentals of cryptography and how it is used to protect data and authenticate transactions. We have looked at encryption, hashing, public key cryptography, and digital signatures. We have also explored how cryptography is used in the real world.
