HarmonyOS字符串SHA-1开发问题

try { 
  MessageDigest digest = java.security.MessageDigest.getInstance("SHA-1"); 
  digest.update(decript.getBytes("UTF-8")); 
  byte[] messageDigest = digest.digest(); 
  // Create Hex String 
  StringBuffer hexString = new StringBuffer(); 
  // 字节数组转换为 十六进制 数 
  for (int i = 0; i < messageDigest.length; i++) { 
    String shaHex = Integer.toHexString(messageDigest[i] & 0xFF); 
    if (shaHex.length() < 2) { 
      hexString.append(0); 
    } 
    hexString.append(shaHex); 
  } 
  return hexString.toString(); 
} catch (Exception e) { 
  return "ERROR"; 
}
