Recently, Jason invited Mei from the Mathematics Department of Fudan University to give five hardcore math classes for friends interested in Web3. Starting from natural numbers, he explained the details of RSA asymmetric encryption. Let me review and try to explain this rather complex topic. (Math warning ahead, but I promise to limit it to … Read more
Source:http://dwz.date/afUd 1. Basic Concepts of Encryption “Encryption” is a technology that restricts access to data transmitted over the network. The original data (also known as plaintext) is encoded into ciphertext by encryption devices (hardware or software) and keys. The process of restoring ciphertext back to the original plaintext is called decryption, which is the reverse … Read more

Main Cybersecurity Threats • Unauthorized access • Information leakage or loss • Data integrity destruction • Denial of Service (DoS) attacks • Spreading … Read more
Background Recently, some security requirements were rectified in the project. Encryption is one of the commonly used means during the process. Here is a brief summary, hoping to help everyone. Usage Scenarios Encryption is a process that transforms raw information (plaintext) into a form (ciphertext) that is difficult to understand directly. The main purpose is … Read more

Typically, in interactions with servers, to ensure the security of data transmission and prevent data tampering, in addition to the … Read more
Crypto++: A Powerful Encryption Library in C++ Crypto++ is an efficient and feature-rich encryption library widely used for implementing data encryption, digital signatures, cryptographic protocols, and more. It offers a plethora of encryption algorithms, including symmetric encryption, asymmetric encryption, hashing algorithms, and digital certificate management. As an open-source project, the flexibility and extensibility of Crypto++ … Read more
Hello everyone, I am QiQi AI! Today, let’s explore the world of data encryption in Python. Imagine that PyCrypto is like a magical key🔑 that can turn your data into ciphertext that only specific people can understand. It’s like the password games we played in childhood, but this time it’s real professional encryption technology! Basic … Read more
If you are still using GSM phones based on earlier signal standards, you better be a bit cautious while using your phone. According to recent reports from foreign media, security researchers have found that they only need to use three NVIDIA GeForce GTX690 graphics cards (GPU) to crack the GSM A5 encryption algorithm. What Is … Read more
