Question

HarmonyOS中HmacSHA1加签算法实现？
kotlin:

fun genHMAC(data: ByteArray, key: ByteArray): ByteArray? { 
  var result: ByteArray? = null 
  try { 
  //根据给定的字节数组构造一个密钥,第二参数指定一个密钥算法的名称 
  val signinKey = SecretKeySpec(key, "HmacSHA1") 
  //生成一个指定 Mac 算法 的 Mac 对象 
  val mac: Mac = Mac.getInstance("HmacSHA1") 
  //用给定密钥初始化 Mac 对象 
  mac.init(signinKey) 
  //完成 Mac 操作 
  val rawHmac: ByteArray = mac.doFinal(data) 
  result = bytesToHexStr(rawHmac).toByteArray() 
} catch (e: NoSuchAlgorithmException) { 
  e.printStackTrace() 
} catch (e: InvalidKeyException) { 
  e.printStackTrace() 
} 
return result 
}

HMAC-SHA1 签名生成时java版本与ArkTS版本生成的结果不一致，请问下ArkTS版本这里如何使用HMAC-SHA1 签名

Answer 1

具体参考代码如下：

async function calculateHmacSHA1Test() { 
  try { 
    let macAlgName = "SHA1"; //SHA256 
    let key = "12345xxxxxcdefgh"; 
    key = "dshsja1234561xxxxxmdda12d1s"; 
    let keyBytes = stringToUint8Array(key); 
    console.info("[ETS HMAC]: key bytes : " + keyBytes); 
    let message = "hmacTestMessgae"; 
    let dataBytes = stringToUint8Array(message); 
    console.info("[ETS HMAC]: message bytes : " + dataBytes); 
    let symKey = await cryptoFramework.createSymKeyGenerator("HMAC").convertKey({ data: keyBytes }); 
    let mac = cryptoFramework.createMac(macAlgName); 
    await mac.init(symKey); 
    await mac.update({ data: dataBytes }); 
    let macOutput = await mac.doFinal(); 
    let str = uint8ArrayToHexStr(macOutput.data) 
    console.info("[ETS HMAC]: result bytes : " + macOutput.data); 
    console.info("[ETS HMAC]: result string : " + str); 
  }catch (err){ 
    console.error(err) 
  } 
} 
// 字符串转成字节流 
export function stringToUint8Array(str: string) { 
  return new Uint8Array(buffer.from(str,'utf-8').buffer); 
} 
export function uint8ArrayToHexStr(data: Uint8Array): string { 
  return buffer.from(data).toString('hex'); 
}
