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 speeds of the algorithms are evaluated and compared. The simulation is conducted using C#. Keywords: Encryption Algorithms, Performance, Analysis, AES, DES, Blowfish, TripleDES, Cryptography … Read more
At three in the morning, I was staring at the abnormal login records suddenly appearing on the production environment monitoring screen— a test account attempted to log in with a password 300 times within 5 minutes. This reminded me of a data breach incident I personally experienced three years ago: an e-commerce system used MD5 … Read more
