How do we know SymmetricAlgorithmNames::AesCbc is 128 bit or 256 bit in WinRT?

    Question

  • I am using SymmetricAlgorithmNames::AesCbc and SymmetricAlgorithmNames::DesCbc algorithms in my Data Encryption implementation in WinRT.

    I need to ensure that these algorithms are at least 128 bit algorithms which is not evident from the algorithm names. The same is evident if we are using OpenSLL (eg. EVP_aes_128_cfb128()).

    Can anyone tell me whether SymmetricAlgorithmNames::AesCbc is 128-bit or 256-bit or something other?

    Thanks in advance.
