She is known as the “Queen of Cryptography” in China and is a mathematical genius that gives headaches to American intelligence agencies. She led her team to successively crack globally recognized secure encryption algorithms such as MD5 and SHA-1, shocking the international cryptography community and forcing the U.S. National Institute of Standards and Technology (NIST) … Read more
Error: error:0308010C:digital envelope routines::unsupported This is usually because Node.js is attempting to use an unsupported cryptographic algorithm or option. Solution: 1. Roll back to a lower, compatible version. 2. Add the following statement to the startup command (Windows): # Before modification: "dev": "cross-env PATH_TYPE=dev nuxt",# After modification: "dev": "SET NODE_OPTIONS=–openssl-legacy-provider && cross-env PATH_TYPE=dev nuxt", There … Read more
RSA (Rivest-Shamir-Adleman) is a classic asymmetric encryption algorithm proposed by three cryptographers Ron Rivest, Adi Shamir, and Leonard Adleman in 1977. Its core function is to achieve secure communication through public key encryption and private key decryption, widely used in digital signatures, SSL/TLS protocols, data encryption, and other fields. Key Generation Principle of RSA Significance … Read more

The historical development of cryptographic algorithms is a reflection of the continuous struggle and progress of human intelligence and technology. Below is a detailed chronological introduction: 1. Classical Cryptography (Before 5th Century) Caesar Cipher (1st Century BC) The earliest monoalphabetic substitution cipher, which encrypts by shifting the alphabet by a fixed number of positions (e.g., … Read more
Homomorphic encryption (HE) is a special encryption mode in cryptography that satisfies the property of homomorphic operations on ciphertexts. This means that after data is homomorphically encrypted, specific calculations can be performed on the ciphertext, and the result of these calculations, when subjected to corresponding homomorphic decryption, will be equivalent to performing the same calculations … Read more
