Aim to be simple and fast.  

## Features
- Port Scan
- Host Scan
- Async Port Scan (Currently only Unix-Like OS is supported)
- Async Host Scan (Currently only Unix-Like OS is supported)

## Installation
### Cargo Install
```
cargo install nscan
```

## Basic Usage
```
USAGE:
    nscan [FLAGS] [OPTIONS]

FLAGS:
    -d, --detail                Get details (service version)
    -A, --acceptinvalidcerts    Accept invalid certs (This introduces significant vulnerabilities)
    -a, --async                 Perform asynchronous scan
    -h, --help                  Prints help information
    -V, --version               Prints version information

OPTIONS:
    -p, --port <ip_addr:port>        Scan ports of the specified host. 
                                     Use default port list if port range omitted. 
                                     Examples 
                                     -p 192.168.1.8 -d

                                     -p 192.168.1.8:22,80,8080 
                                     -p 192.168.1.8 -l custom-list.txt
    -n, --host <ip_addr>             Scan hosts in specified network or list 
                                     Examples 
                                     -n 192.168.1.0 -d 
                                     -n -l custom-list.txt
    -t, --timeout <duration>         Set timeout in ms - Ex: -t 10000
    -w, --waittime <duration>        Set waittime in ms (default:100ms) - Ex: -w 200
    -P, --portscantype <scantype>    Set port scan type (default:SYN) - SYN, CONNECT
    -i, --interface <name>           Specify network interface by IP address - Ex: -i 192.168.1.4
    -l, --list <file_path>           Use list - Ex: -l custom-list.txt
    -s, --save <file_path>           Save scan result to file - Ex: -s result.txt
```

## Example
Port scan and service version detection   
```
sudo nscan -p 192.168.1.8 -d 
```

Host scan  
```
sudo nscan -n 192.168.1.0   
```

-a(--async) flag for asynchronous scan  
-s(--save) option for save json format data to file  

## Supported platforms
