1.2. Block cipher public types

group CMOX_BLOCKCIPHER_PUBLIC_TYPES

Typedefs

typedef const struct cmox_blockcipher_vtableStruct_st * cmox_blockcipher_vtable_t

Block cipher algorithm type.

This type is defined as a pointer to a structure that contains the functions needed for the specific algorithm, as defined internally in the library.

struct cmox_blockcipher_handle_t

#include <cmox_blockcipher.h>

Block cipher context handle.

Public Members
