metric indicates if the probe succeeded. Adding a `debug=true` parameter
will return debug information for that probe.
+### TLS and basic authentication
+
+The Blackbox Exporter supports TLS and basic authentication. This enables better
+control of the various HTTP endpoints.
+
+To use TLS and/or basic authentication, you need to pass a configuration file
+using the `--web.config.file` parameter. The format of the file is described
+[in the exporter-toolkit repository](https://github.com/prometheus/exporter-toolkit/blob/master/docs/web-configuration.md).
+
+Note that the TLS and basic authentication settings affect all HTTP endpoints:
+/metrics for scraping, /probe for probing, and the web UI.

+# Backoff
+
+A simple exponential backoff counter in Go (Golang)
+
+[](https://godoc.org/github.com/jpillora/backoff) [](https://circleci.com/gh/jpillora/backoff)
+
+### Install
+
+```
+$ go get -v github.com/jpillora/backoff
+```
+
+### Usage
+
+Backoff is a `time.Duration` counter. It starts at `Min`. After every call to `Duration()` it is multiplied by `Factor`. It is capped at `Max`. It returns to `Min` on every call to `Reset()`. `Jitter` adds randomness ([see below](#example-using-jitter)). Used in conjunction with the `time` package.
+
+---
+
+#### Simple example
+
+``` go
+
+b := &backoff.Backoff{
+ //These are the defaults
+ Min: 100 * time.Millisecond,
+ Max: 10 * time.Second,
+ Factor: 2,
+ Jitter: false,
+}
+
+fmt.Printf("%s\n", b.Duration())
+fmt.Printf("%s\n", b.Duration())
+fmt.Printf("%s\n", b.Duration())
+
+fmt.Printf("Reset!\n")
+b.Reset()
+
+fmt.Printf("%s\n", b.Duration())
+```
+
+```
+100ms
+200ms
+400ms
+Reset!
+100ms
+```
+
+---
+
+#### Example using `net` package
+
+``` go
+b := &backoff.Backoff{
+ Max: 5 * time.Minute,
+}
+
+for {
+ conn, err := net.Dial("tcp", "example.com:5309")
+ if err != nil {
+ d := b.Duration()
+ fmt.Printf("%s, reconnecting in %s", err, d)
+ time.Sleep(d)
+ continue
+ }
+ //connected
+ b.Reset()
+ conn.Write([]byte("hello world!"))
+ // ... Read ... Write ... etc
+ conn.Close()
+ //disconnected
+}
+
+```
+
+---
+
+#### Example using `Jitter`
+
+Enabling `Jitter` adds some randomization to the backoff durations. [See Amazon's writeup of performance gains using jitter](http://www.awsarchitectureblog.com/2015/03/backoff.html). Seeding is not necessary but doing so gives repeatable results.
+
+```go
+import "math/rand"
+
+b := &backoff.Backoff{
+ Jitter: true,
+}
+
+rand.Seed(42)
+
+fmt.Printf("%s\n", b.Duration())
+fmt.Printf("%s\n", b.Duration())
+fmt.Printf("%s\n", b.Duration())
+
+fmt.Printf("Reset!\n")
+b.Reset()
+
+fmt.Printf("%s\n", b.Duration())
+fmt.Printf("%s\n", b.Duration())
+fmt.Printf("%s\n", b.Duration())
+```
+
+```
+100ms
+106.600049ms
+281.228155ms
+Reset!
+100ms
+104.381845ms
+214.957989ms

+# Usernames and hashed passwords that have full access to the web
+# server via basic authentication. If empty, no basic authentication is
+# required. Passwords are hashed with bcrypt.
+basic_auth_users:
+ [ <string>: <secret> ... ]
+```
+
+## About bcrypt
+
+There are several tools out there to generate bcrypt passwords, e.g.
+[htpasswd](https://httpd.apache.org/docs/2.4/programs/htpasswd.html):
+
+`htpasswd -nBC 10 "" | tr -d ':\n'`
+
+That command will prompt you for a password and output the hashed password,
+which will look something like:
+`$2y$10$X0h1gDsPszWURQaxFh.zoubFi6DXncSjhoQNJgRrnGs7EsimhC7zG`
+
+The cost (10 in the example) influences the time it takes for computing the
+hash. A higher cost will en up slowing down the authentication process.
+Depending on the machine, a cost of 10 will take about ~70ms where a cost of
+18 can take up to a few seconds. That hash will be computed on every
+password-protected request.
