The RSA algorithm is the first algorithm that can be used for both data encryption and digital signature. It is easy to understand and operate, and is also popular. Its security is based on the difficulty of big integer factorization, while the big integer factorization is a famous mathematical problem. So far, there is no effective solution, therefore, the security of the RSA algorithm can be ensured. The RSA algorithm consists of the generation of

Introduction to Cryptographic algorithms I. Cryptography INTRODUCTION According to records, in 400 BC, the ancient Greeks invented the replacement code. 1881 the world's first telephone secrecy patent appeared. During the Second World War, the German military enabled the "Enigma" cipher Machine, which played a very important role in the war. With the development of information and digital society, People's awareness of the importance of security and confidentiality has been increasing, so in 19

Piracy is a worrying issue for most software developers. Will the software encrypted with encryption locks be cracked by hackers? Theoretically, there is no software that cannot be cracked. Even pure mathematical encryption may be cracked, but the time for cracking may be an astronomical number. Currently, there are two types of encryption locks on the market: th

ASP. NET has no magic-encryption and decryption of ASP. NET Identity, and identity encryption and decryption The previous article introduced how to use Identity in ASP. net mvc to Implement User Registration, logon, and authentication. These functions are related to user information security, and the importance of data security is always the first. For the registration and login functions, the password and

1. Overview of cryptographic algorithmsThe encryption algorithm can be divided into reversible and non-reversible encryption depending on whether the content is restored.Reversible encryption can be divided into symmetric and asymmetric encryption according to whether the same key is used for

Those who know Data Encryption technology are sure to be confident in its ability to protect the security of data sources. Because of the direct effect on data, even if the data is lost or stolen in the security crisis, encryption protection can still ensure the security of the real data content. However, the flexibility of data encryption has always been critici

This article is a basic article on Software encryption technology. It briefly introduces some basic knowledge about Software Encryption and some encryption products. It is suitable for domestic software developers or individual software developers to share their reference. 　　1. encryption technology Overview The securi

All we need to do is to declare a column to be encrypted and the rest to be done by Oracle. When the user inserts or updates data, the column values are intercepted, encrypted, and then saved in the encrypted format. Then, when the column is queried, the value of the column is automatically decrypted, and the decrypted text (plaintext) is returned to the user. Users do not even need to know that there has been encryption and decryption--the so-called
