2.3. CMOX CTR DRBG PUBLIC METHODS

group CMOX_CTR_DRBG_PUBLIC_METHODS

Functions

cmox_drbg_handle_t * cmox_ctr_drbg_construct ( cmox_ctr_drbg_handle_t * P_pThis , cmox_ctr_drbg_impl_t P_impl )

CTR-DRBG constructor.

The function is used for specifying which block cipher algorithm to use in order to implement the CTR-DRBG algorithm

Parameters :

  • P_pThis – Pointer to the CTR-DRBG handle to initialize

  • P_impl – Constant that specifies the implementation to use. This parameter can be one of the following values:

    • CMOX_CTR_DRBG_AES128_FAST

    • CMOX_CTR_DRBG_AES192_FAST

    • CMOX_CTR_DRBG_AES256_FAST

    • CMOX_CTR_DRBG_AES128_SMALL

    • CMOX_CTR_DRBG_AES192_SMALL

    • CMOX_CTR_DRBG_AES256_SMALL

Returns :

cmox_drbg_handle_t* Pointer to a general DRBG handle. This will be used by the general purpose cipher functions in order to perform the algorithm

2.4. CMOX CTR DRBG PUBLIC TYPES

group CMOX_CTR_DRBG_PUBLIC_TYPES

Typedefs

typedef const struct cmox_ctr_drbg_implStruct_st * cmox_ctr_drbg_impl_t

CTR-DRBG mode implementation.

This type specifies the used block cipher for the CTR-DRBG construct. This type is defined as a pointer to a structure, that contains the functions needed for the specific implementation, defined in the library internally

struct cmox_ctr_drbg_state_t
#include <cmox_ctr_drbg.h>

Structure to store the state/context of the CTR_DRBG.

struct cmox_ctr_drbg_handle_t
#include <cmox_ctr_drbg.h>

CTR-DRBG handle structure definition.
