With cybercrime being so rampant, what should you do if your data is seen or even stolen by others? Data encryption is a common and effective security method and is the first choice for protecting enterprise data. But how do you encrypt data? Do you know what technologies are involved? Today, we will learn about … Read more
Written by: Jiu Ge In 1977, three mathematicians Rivest, Shamir, and Adleman proposed a new asymmetric encryption algorithm, named after themselves, known as the RSA encryption algorithm. The knowledge of RSA involves advanced mathematics such as number theory and Euler’s function. If you do not have a background in higher mathematics, it is recommended not … Read more
0. Introduction In this article, we will introduce the encryption and decryption in .NET Core. In web applications, user passwords are stored as MD5 hashes. In other cases, encryption and decryption functionalities are also used. Common encryption algorithms are divided into symmetric and asymmetric encryption. Symmetric encryption means that the encryption key and the decryption … Read more
There are three types of Java encryption algorithms: 1. One-way encryption algorithm 2. Symmetric encryption algorithm 3. Asymmetric encryption algorithm One-way Encryption Algorithm One-way encryption is an irreversible encryption algorithm, and the encrypted ciphertext cannot be decrypted. Common algorithms include MD5, SHA, and HMAC. MD5 (Message-Digest Algorithm) No matter how long the data is, it … Read more
Hi everyone, I am Hu Ge. Recently, while handling user login functionality in a project, I encountered a “common issue”—how to securely store user passwords. As a programmer who has been battling on the front line for years, I am very aware of how sensitive password storage is. Especially if the database is compromised, and … Read more
Introduction to Cryptography Cryptography is a young yet ancient discipline. It has been used to protect military and diplomatic communications for thousands of years. The earliest recorded communication cipher dates back to 400 BC. The ancient Greeks invented substitution ciphers. In 1881, the world’s first telephone secrecy patent emerged. The invention of the telegraph and … Read more
1 This Article's Purpose In using the Qiling simulation execution framework on the Windows platform, I encountered many difficulties, and some issues did not have solutions found through research. Therefore, I am writing this article, hoping it can provide some reference for everyone. The following points are listed as the content I want to express … Read more
A prime number is also called a prime, which refers to a natural number greater than 1 that has no other factors apart from 1 and itself. If a natural number can be expressed as the product of two prime numbers, that natural number is called a semiprime (also known as a biprime or a … Read more
1. MD5 Encryption MD5 encryption characteristics: irreversible operation (cannot be cracked, cannot be decrypted) The result of encrypting different data is a fixed-length 32-character string (no matter how large the file is, it remains the same). The result of encrypting the same data is the same (that is, it is copied). Resistance to modification: the … Read more
In interface automation, we often encounter situations where passwords need to be encrypted. Sometimes, we look for developers to solve this. However, test engineers can also solve it themselves. Below, I will introduce the methods and applications of encryption in requests. Characteristics and Processing of MD5 Encryption Symmetric encryption algorithms: The same key is used … Read more
