CryptUnprotectData

[Koak]

I have included wincrypt.h but when I try to compile I get an error.
`CryptUnprotectData' undeclared (first use this function)

I am using bloodsheds Dev-C++ IDE.

Thanks in advance.

Open up wincrypt.h and check that the function exists in there, and that you're spelling it correctly, and that you're passing it the correct variables.

I have checked and the CryptUnprotectData function is not in there while it should be.
This is my wincrypt.h: http://pastebin.com/d6TW8bL2

it should look something like

WINCRYPT32API
BOOL
WINAPI
CryptUnprotectData(
    __in DATA_BLOB* pDataIn,
    __deref_opt_out_opt LPWSTR* ppszDataDescr,
    __in_opt DATA_BLOB* pOptionalEntropy,
    __reserved PVOID pvReserved,
    __in_opt CRYPTPROTECT_PROMPTSTRUCT* pPromptStruct,
    __in DWORD dwFlags,
    __out DATA_BLOB* pDataOut
    );

Seems you've got the wrong wincrypt.

[Koak]

it's the one included in the Dev-C++ 5 beta

You think I could just replace mine with a working one (like the one included in Visual Studio 2010)?

Your choice of IDE is crippling you.

I think you should dump it and get something that works.

Alright, thanks.
