Signing HTTP Messages Middleware base on [HTTP Signatures](https://tools.ietf.org/html/draft-cavage-http-signatures).

## Example

``` go

package main

import (
"github.com/gin-contrib/httpsign"
"github.com/gin-contrib/httpsign/crypto"
"github.com/gin-gonic/gin"
)

func main() {
// Define algorithm
hmacsha256 := &crypto.HmacSha256{}
hmacsha512 := &crypto.HmacSha512{}
// Init define secret params
readKeyID := httpsign.KeyID("read")
writeKeyID := httpsign.KeyID("write")
secrets := httpsign.Secrets{
readKeyID: &httpsign.Secret{
Key: "HMACSHA256-SecretKey",
Algorithm: hmacsha256, // You could using other algo with interface Crypto
},
writeKeyID: &httpsign.Secret{
Key: "HMACSHA512-SecretKey",
Algorithm: hmacsha512,
},
}

// Init server
r := gin.Default()

//Create middleware with default rule. Could modify by parse Option func
auth := httpsign.NewAuthenticator(secrets)

r.Use(auth.Authenticated())
r.GET("/a", a)
r.POST("/b", b)
r.POST("/c", c)

r.Run(":8080")
}
```
