Repeat the encryption using the same datafile and key on your Arduino.Compare the output files. Are they identical? If they are, the problem is likely to be in your C# code, and you need to try feeding the known-good-output into that and see what you get. If they aren't, the problem is at the Arduino end, and you need to look at exactly what you are doing there.We can't do that for you! 这篇关于AES arduino加密代码解密成C#的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持! 上岸,阿里云! 07-31 09:32
