t_cose_key Struct Reference

#include <t_cose_common.h>

Data Fields
enum t_cose_crypto_lib_t	crypto_lib
union {
void *   key_ptr
uint64_t   key_handle
}	k

Detailed Description

This structure is used to indicate or pass a key through the t_cose implementation to the underlying, platform-specific cryptography libraries for signing and verifying signature. You must know the cryptographic library that is integrated with t_cose to know how to fill in this data structure.

For example, in the OpenSSL integration, key_ptr should point to an OpenSSL EVP_KEY type.

Field Documentation

crypto_lib

enum t_cose_crypto_lib_t t_cose_key::crypto_lib

Identifies the crypto library this key was created for. The crypto library knows if it uses the handle or the pointer so this indirectly selects the union member.

key_handle

uint64_t t_cose_key::key_handle

For libraries that use an integer handle to the key

key_ptr

void* t_cose_key::key_ptr

For libraries that use a pointer to the key or key handle. NULL indicates empty.
