CRYPT_HmacCallback typedef int32_t(* CRYPT_HmacCallback) (HITLS_HashAlgo hashAlgo, const uint8_t *key, uint32_t keyLen, const uint8_t *in, uint32_t inLen, uint8_t *out, uint32_t *outLen) Function for calculating the HMAC for a single time 参数 hashAlgo [IN] Hash algorithm key [IN] Key keyLen [IN] Key length in [IN] Input data. inLen [IN] Input data length out [OUT] Output the HMAC data result. outLen [IN/OUT] IN: Maximum buffer length OUT: Output data length 返回值 0 indicates success. Other values indicate failure.
