Click the blue text Follow us The Birth of Asymmetric Encryption Tree Brother: Cryptography can be simply divided into classical cryptography and modern cryptography. We have already introduced substitution ciphers and the Enigma machine in classical cryptography, and now we will begin to discuss symmetric and asymmetric encryption methods in modern cryptography. I’m sure you … Read more
1. Definition of Cryptography Before the late 20th century, cryptography was more of an art, primarily used for secret communication. At that time, there were no theories to rely on, nor any effective definitions to construct a good cipher. It wasn’t until the 1980s that the emergence of modern cryptography transformed the study of cryptography … 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

Source: blog.csdn.net/qq_36470686/ article/details/85206648 1. Overview In the field of security, using key encryption algorithms to encrypt the communication process is a common security measure. This method can ensure three goals of secure data communication: 1. Data confidentiality, preventing user data from being stolen or leaked. 2. Ensuring data integrity, preventing the user’s transmitted data from … Read more
A Revolutionary Algorithm Earth-Shattering A cryptographic algorithm that can only be cracked by computational power 1 The History of Cryptography 5th Century BC, the ancient Greeks used a stick called scytale to transmit encrypted messages. To encrypt, a strip of paper was wrapped around the stick, and the message was written horizontally along the stick. … Read more

Alan Turing was primarily responsible for breaking the German Enigma cipher system during World War II. Decrypting codes required extensive computation, and Turing understood that to do a good job, one must first sharpen their tools. Thus, a computer called COLOSSUS was developed in 1943, and a total of 10 such electronic computers were produced, … Read more
