Cryptography is a technique used to protect information from unauthorized access. It is a mathematical science that uses mathematical algorithms to encode and decode data.
Cryptography is used in many different applications, including email, file sharing, and secure communications. It is also used to protect information from being intercepted or decoded by unauthorized people.
Cryptography is a very important part of software development. It is used to protect information from being accessed by unauthorized people. It is also used to ensure that information is not tampered with.
Cryptography is a very complex topic. In this post, we will focus on the basics of cryptography. We will learn about the different types of cryptography, the different algorithms, and the different ways to protect information.
There are two main types of cryptography: symmetric cryptography and asymmetric cryptography.
Symmetric cryptography, also known as secret key cryptography, is a type of cryptography where the same key is used to encrypt and decrypt data. The key must be kept secret. If the key is compromised, the data is also compromised.
Asymmetric cryptography, also known as public key cryptography, is a type of cryptography where two different keys are used to encrypt and decrypt data. The two keys are called the public key and the private key. The public key can be shared with anyone. The private key must be kept secret.
Cryptographic algorithms are mathematical algorithms that are used to encode and decode data. There are many different cryptographic algorithms. Some of the most popular algorithms are:
There are many different ways to protect information. Some of the most popular methods are:
Encryption: Encryption is a process of transforming readable data into an unreadable format. This prevents unauthorized people from reading the data.
Hashing: Hashing is a process of creating a fixed-size value from a piece of data. This can be used to verify the data has not been tampered with.
Digital signatures: A digital signature is a way to verify that a piece of data has not been tampered with. It is created using a private key.
