Encrypt and decrypt a string in C# and C++

[speed780]

Hello,

I would like to encrypt and decrypt a string in C# and C++ Qt. I know there is AES256, but when I use some code from AES256 in C# and C++ Qt, I have different result for the encryption of the string, but the decryption is correct.

So I wonder how with a different result of encryption, we obtain a good decryption, it is very strange for me.

So, I would want to know if there is a good alternative in C# and C++ Qt to encrypt end decrypt a string without using AES256?


Thanks.
