# pwned-passwords
[![GoDoc](https://godoc.org/github.com/mattevans/pwned-passwords?status.svg)](https://godoc.org/github.com/mattevans/pwned-passwords)
[![Build Status](https://travis-ci.org/mattevans/pwned-passwords.svg?branch=master)](https://travis-ci.org/mattevans/pwned-passwords)
[![Go Report Card](https://goreportcard.com/badge/github.com/mattevans/pwned-passwords)](https://goreportcard.com/report/github.com/mattevans/pwned-passwords)
[![license](https://img.shields.io/github/license/mashape/apistatus.svg)](https://github.com/mattevans/pwned-passwords/blob/master/LICENSE)
A simple [Go](http://golang.org) client library for checking compromised passwords against [HIBP Pwned Passwords](https://haveibeenpwned.com/Passwords).
Upon request, results will be cached (in-memory), keyed by hash. With a two hour expiry window, subsequent requests will use cached data or fetch fresh data accordingly.
Installation
-----------------
`go get -u github.com/mattevans/pwned-passwords`
Usage
-----------------
```go
package main
import (
"fmt"
hibp "github.com/mattevans/pwned-passwords"
"os"
)
func main() {
// Init a client.
client := hibp.NewClient()
// Check to see if your given string is compromised.
pwned, err := client.Pwned.Compromised("string to check")
if err != nil {
fmt.Println("Pwned failed")
os.Exit(1)
}
if pwned {
// Oh dear!
// You should avoid using that password
} else {
// Woo!
// All clear!
}
}
```
**Expire in-memory cache**
```go
client.Cache.Expire(HASHED_VALUE)
```
```go
client.Cache.ExpireAll()
```
