-Let fp work with Cookie, cross-domain, make it stable and reliable!
+The simplified usage of [fingerprintjs/fingerprintjs2](https://github.com/fingerprintjs/fingerprintjs2).
## What is fp?
-fp is a concise web front-end solution to generate an unique 'fingerprint' for each visitor basing on visitor's device and browser.
+fp is a concise web front-end solution to generate an unique 'fingerprint' for each visitor basing on visitor's device and browser. fp is the simplified usage of [fingerprintjs/fingerprintjs2](https://github.com/fingerprintjs/fingerprintjs2). Without complex configuration, fp can provide an optimized fingerprint for user-agents in form of 6 letters hash in a short time.
## Quick start
-[Click here to see how it works!](https://fp.yimian.xyz/demo.html)
+[Click here to see how it works!](./demo.html)
## How to use fp?
To use fp, you must include the fp.js or fp.min.js first.
A simple example:
```html
-
+
```
-## Advanced Usage
-
-### Get fp
-```html
-
-
+This will generate a six-letter hash like this (For difficult client this hash is unique):
+```bash
+df3kd0
```
+The first two letters `df` indicates the fingerprint of the device, such as the PC, phone etc. Ideally, these two letter will not vary while you switch the browser on the same device.
-### Recover fp from key (cross-domain purpose)
-```html
-
-
-```
+The middle two letters `3k` and the last two letters `d0` are the fingerprint of the browser. The different is that, the last one could vary with the change of timezone, plugin etc., while the middle one is more stable and will not vary under these stuation. However, the middle part is more likely to be "not unique" when you have a great amount of clients.
-### Reset fp
-```html
-
-
-```
-
-### Cookie
-fp preloads [iotcat/cookie-js](https://github.com/iotcat/cookie-js), support all of its functions.
+In practice, you can use `substr()` to decompose fp into each part.
+```js
+ ;(async function(){
+ var fp_device = (await fp).substr(0, 2); //df in df3kd0
+ var fp_browser = (await fp).substr(2, 2); //3k in df3kd0
+ var fp_unique = (await fp).substr(4); //d0 in df3kd0
+ })()
+````
-**usage**
-`cookie.set(key, val, days)`: set a cookie, with key name, value, days to live(defaule: 10 years)
-`cookie.get(key)`: get cookie with key
-`cookie.del(key)`: delete cookie with key
-**example**
-```js
-//set a cookie named iotcat，its value is hero，live for 30 days
-cookie.set("iotcat", "hero", 30);
+## Advanced Usage
-//get the value of the cookie iotcat
-alert(cookie.get("iotcat"));
-//delete the cookie of iotcat
-cookie.del("iotcat");
+### Get fp details
+```html
+
+
```
