3.4. CMOX CBC PUBLIC METHODS

group CMOX_CBC_PUBLIC_METHODS

Functions

cmox_cipher_handle_t * cmox_cbc_construct ( cmox_cbc_handle_t * P_pThis , cmox_cbc_impl_t P_impl )

CBC constructor.

The function is used for specifying which block cipher algorithm to use in order to implement the CBC algorithm and if the algorithm will be used for encryption or decryption.

Parameters :

• P_pThis – Pointer to the CBC handle to initialize

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

  • CMOX_AESFAST_CBC_ENC

  • CMOX_AESFAST_CBC_DEC

  • CMOX_AESSMALL_CBC_ENC

  • CMOX_AESSMALL_CBC_DEC

  • CMOX_SM4_CBC_ENC

  • CMOX_SM4_CBC_DEC

Returns :

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

3.5. CMOX CBC PUBLIC TYPES

group CMOX_CBC_PUBLIC_TYPES

Typedefs

typedef const struct cmox_cbc_implStruct_st * cmox_cbc_impl_t

CBC mode implementation.

This type specifies the used block cipher for the CBC construct and if the algorithm will be used for encryption or decryption. 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_cbc_handle_t

#include <cmox_cbc.h>

CBC handle structure definition.
