Parameters for miscellaneous simple key derivation mechanisms

CK_KEY_DERIVATION_STRING_DATA; CK_KEY_DERIVATION_STRING_DATA_PTR

CK_KEY_DERIVATION_STRING_DATA provides the parameters for the CKM_CONCATENATE_BASE_AND_DATA, CKM_CONCATENATE_DATA_AND_BASE, and CKM_XOR_BASE_AND_DATA mechanisms. It is defined as follows:

typedef struct CK_KEY_DERIVATION_STRING_DATA {
CK_BYTE_PTR pData;
CK_ULONG ulLen;
} CK_KEY_DERIVATION_STRING_DATA;

pData pointer to the byte string

ulLen length of the byte string

CK_KEY_DERIVATION_STRING_DATA_PTR is a pointer to a CK_KEY_DERIVATION_STRING_DATA.

CK_EXTRACT_PARAMS; CK_EXTRACT_PARAMS_PTR

CK_KEY_EXTRACT_PARAMS provides the parameter to the CKM_EXTRACT_KEY_FROM_KEY mechanism. It specifies which bit of the base key should be used as the first bit of the derived key. It is defined as follows:

typedef CK_ULONG CK_EXTRACT_PARAMS;

CK_EXTRACT_PARAMS_PTR is a pointer to a CK_EXTRACT_PARAMS.
