01 “Passwords” and “Passcodes” The term “password” mentioned in real life, such as the boot “password”, WeChat “password”, and bank card payment “password”, actually refers to passcodes. A passcode is merely a “ticket” to access personal computers, mobile phones, email accounts, or personal bank accounts; it is a simple, basic means of identity authentication. These … Read more
1. “Password” and “Passphrase” In real life, the term “password” refers to things like the startup “password” for devices, WeChat “passwords”, and bank card payment “passwords”. These “passwords” are actually passphrases. A passphrase is merely a “pass” to access personal computers, mobile phones, email accounts, or personal bank accounts; it is a simple, basic method … Read more
Security Background In the digital age, we deal with various “secrets”: our bank passwords, payment information, private chats… How can we ensure that this information is not intercepted or tampered with during network transmission? This relies heavily on powerful encryption algorithms. Today, we will delve into our country’s independent cryptographic standard —SM2 encryption algorithm. As … Read more
In the digital world, we exchange information every day: online shopping payments, WeChat chats, online office work, and even scanning codes to take the subway… Behind these conveniences lies an invisible “security guard”—encryption algorithms. You may have heard of international mainstream algorithms like RSA and ECC, but today, we will discuss a “guardian of security” … Read more
