## Member Function Documentation

## generate() [1/2]

int hmac::generate | ( | const std::vector< unsigned char > | p_buffer,
|  | const std::vector< unsigned char > | p_secret_key,
|  | std::vector< unsigned char > & | p_hmac
| ) |  |

inline

Generate the HMAC of data using a secret key [in] p_buffer The data tobe hashed.

Parameters

  [in] | p_secret_key | The secret key to be used to generate the HMAC
  [out] | p_hmac | The HMAC value based of the provided data

Returns
  0 on success, -1 otherwise

## generate() [2/2]

int hmac::generate | ( | const unsigned char * | p_buffer,
|  | const size_t | p_buffer_length,
|  | const unsigned char * | p_secret_key,
|  | const size_t | p_secret_key_length,
|  | std::vector< unsigned char > & | p_hmac
| ) |  |

inline

Generate the HMAC of data using a secret key.

Parameters

  [in] | p_buffer | The data to be hashed
  [in] | p_buffer_length | The size of the data
  [in] | p_secret_key | The secret key to be used to generate the HMAC
  [in] | p_secret_key_length | The size of the secret key
  [out] | p_hmac | The HMAC value based of the provided data

Returns
  0 on success, -1 otherwise
