There are two sayings: 1) Algorithms and data structures are an important part of programming. If you lose algorithms and data structures, you lose everything. 2) Programming is algorithms and data structures; algorithms and data structures are the soul of programming. Note that this is not my own statement, but a summary from countless programmers. … Read more
3DES is the common name for the Triple Data Encryption Standard. It is an enhanced version of the DES algorithm, equivalent to applying the DES operation three times to each data block. Due to the increased key length, the security level and difficulty of cracking are higher than that of the DES algorithm. The encryption … Read more
Click the blue text above “Programming Diary” to follow below National secret algorithms: These are algorithms independently developed by our country to reduce excessive reliance on foreign technology. National secret refers to the domestic cryptographic algorithms recognized by the National Cryptography Administration. The following is the specific correspondence: Symmetric algorithms: AES, DES, SM4 Asymmetric algorithms: … Read more
This article compares the performance of four commonly used encryption algorithms: DES, 3DES, Blowfish, and AES (Rijndael). By running several encryption settings to process data blocks of different sizes, the encryption/decryption speed of the algorithms is evaluated and compared. The simulation is performed using C#. Keywords: encryption algorithms, performance, analysis, AES, DES, Blowfish, TripleDES, cryptography … Read more
