Hi, I’m Lex the Lex who likes to bully Superman

Areas of expertise: Python development, network security penetration, Windows domain control Exchange architecture

Today’s focus: Share an open source project that converts WiFi information (ID+ password) into QR codes

The first effect

​

Here’s what happened

In the age of qr codes

The streets are full of qr codes that can be scanned

​

Today, share an open source project

You can input WiFi information, including WiFi password

Convert it to a QR code, print it out, and stick it on the wall

​

The Intranet can be used at home or in the office

It’s very convenient not to have to ask relatives, friends, and colleagues to enter the password every time

​

The project structure

The project development structure is as follows: front-end development based on JS

​

​

The project download

[root@centos7 data]# wget https://github.com/lexsaints/wifi-card/archive/refs/heads/master.zip
Copy the code

Run based on docker environment, very convenient, a line of code to run up.

Project running

[root@centos7 data]# CD wifi-card/ # view content [root@centos7 wifi-card]# ls Dockerfile LICENSE Json public readme.md SRC yarn.lock # Run [root@centos7 wifi-card]# make runCopy the code

Make Run will start downloading images from the remote repository.

After running successfully, access the server through the Web

http://localhost:8080 # Default port, which can be changed in the configuration file

The Web access effect is as follows:

​

Usage scenarios

Through this, we can input any WiFi information, and then convert it into a QR code for sharing.

Although, by scanning the QR code, will still read the password content. But at least it’s relatively safe.

After all, when we enter a password on a major website, the browser F12 can actually see it
