    And if you have encrypted string as the input for your code, then calling
    CryptDecrypt with proper key or hash value should work as expected.
    However, from your first post. what I got was that you were trying to
    decrypt a plain string which has 128 'A's. Though the buf is just a stream
    of bits and meanless, but if you want want to decrypted with alg&key you
    define, they must be valid for the decrypt process, otherwise, CryptDecrypt
    will fail and you may get NTE_BAD_DATA as last error.
    Since your code looks like a test sample, that is why I suggest you add
    encrypt code to see how it works.
    PS, the code works fine in my side, have you changed MY_DATASIZE 0as
    follows?
            enum
            {
                    MY_BUFSIZE=(32*1024)
                    ,MY_DATASIZE=(117)
            };
