A few days ago, I went to help a friend fix a circuit, only to realize I had forgotten my multimeter at home. My friend looked at me eagerly, his face saying, “Master, please show your skills.” I slapped my forehead and remembered a trick my mentor taught me years ago—using my tongue to measure … Read more
When a recorder is paired with a hard drive or a camera with an SD card, the recorded video files are stored on these media. While it is possible to access the recordings online, there are times when users need to export the video files. What are some quick methods to export recordings? Below are … 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 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
