I'm studying some things about cryptography, and I wonder what is the best system of 128-bit encryption, and how to implement in C/C++ or C#.
Well this is questions that should not be asked as there is no answer to it.
I recommend to use DES(Data encryption system) and AES(Advanced encryption system) as these encryption systems had chosen their underlying algorithms by standardization group and it's the best common option today.
For example if i remember correctly DES uses Rijndael algorithm so look at wiki for it specification.
if you want to know more then I suggest that you look on MSDN at System.Security.Cryptography namespace as there are implemented all most common used algorithms used in cryptography and from there you can look up their specific on wiki or any other source.
If you want to know ore about specific tasks in cryptography then i would be better to specify what exactly you want to encrypt and what you want to have in your application. speed, best data security something in between?
