11.5. CMOX KEYWRAP PUBLIC METHODS

group CMOX_KEYWRAP_PUBLIC_METHODS

Functions

cmox_cipher_handle_t * cmox_keywrap_construct ( cmox_keywrap_handle_t * P_pThis , cmox_keywrap_impl_t P_impl )

KEYWRAP constructor.

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

Parameters :

• P_pThis – Pointer to the KEYWRAP handle to initialize

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

  • CMOX_AESFAST_KEYWRAP_ENC

  • CMOX_AESFAST_KEYWRAP_DEC

  • CMOX_AESSMALL_KEYWRAP_ENC

  • CMOX_AESSMALL_KEYWRAP_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

11.6. CMOX KEYWRAP PUBLIC TYPES

group CMOX_KEYWRAP_PUBLIC_TYPES

Typedefs

typedef const struct cmox_keywrap_implStruct_st * cmox_keywrap_impl_t

KEYWRAP mode implementation.

This type specifies the used block cipher for the KEYWRAP 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_keywrap_handle_t

#include <cmox_keywrap.h>

KEYWRAP handle structure definition.
