Function name : CryptDeriveKey

Group: Cryptography Reference - Library: advapi32

Generates cryptographic session keys derived from a base data value.

Code examples:

A class that encrypts and decrypts files using Cryptography API Functions

Declaration:

BOOL WINAPI CryptDeriveKey(
	HCRYPTPROV hProv,
	ALG_ID Algid,
	HCRYPTHASH hBaseData,
	DWORD dwFlags,
	HCRYPTKEY* phKey
);

FoxPro declaration:

DECLARE INTEGER CryptDeriveKey IN advapi32;
	INTEGER hProv,;
	INTEGER Algid,;
	INTEGER hBaseData,;
	LONG dwFlags,;
	INTEGER @phKey

Parameters:

hProv [in] A HCRYPTPROV handle of a CSP created by a call to CryptAcquireContext.

Algid [in] An ALG_ID structure that identifies the symmetric encryption algorithm for which the key is to be generated.

hBaseData [in] Handle to a hash object that has been fed the exact base data.

dwFlags [in] Specifies the type of key generated.

phKey [in, out] Address to which the function copies the handle of the newly generated key. When you have finished using the key, release the handle by calling the CryptDestroyKey function.

Return value:

If the function succeeds, the function returns nonzero (TRUE).
