I have unsigned char array holding data, I want to store this into a Json object. How can it be done? Using jsoncpp and C++11. the statement
rootL1["CurrentValue"] = userInfo->hashCred;
does not work, in turn it is stored as bool in json instead of the unsigned data.
If you can look into documentation of jsoncpp Value class (I assume rootL1 is of this type, and operator[] returns the same type), you will see that there is no unsigned char* conversion constructor which would accept your userInfo->hashCred array. There is one constructor which accepts const char* but there is no implicit conversion from unsigned char* to const char*, the closest one is implicit conversion of pointer to bool which is choosen in your case.
The solution should be to use conversion constructor which accepts const char*. You should think why you need unsigned char* in the first place, maybe you can use an array of type char? If you cant then you can try casting unsigned char* to char*:
rootL1["CurrentValue"] = reinterpret_cast<char *>(userInfo->hashCred)
but this can cause all sorts of problems depending on what you are actually storing in your array and also what jsoncpp is doing under the hood with this data.
I would suggest you treat your hashCred as binary data and uuencode it to char array. Then store it in jsoncpp Value. For details look into here: Binary data JSONCPP
In jsoncpp test code you can also find some examples of how to store binary data as values.
