# HTTPS Package for Prometheus
The `https` directory contains a Go package and a sample configuration file for
running `node_exporter` with HTTPS instead of HTTP. We currently support TLS 1.3
and TLS 1.2.
To run a server with TLS, use the flag `--web.config`.
e.g. `./node_exporter --web.config="web-config.yml"`
If the config is kept within the https directory.
The config file should be written in YAML format, and is reloaded on each connection to check for new certificates and/or authentication policy.
## Sample Config
```
tls_server_config:
# Certificate and key files for server to use to authenticate to client.
cert_file: <filename>
key_file: <filename>
# Server policy for client authentication. Maps to ClientAuth Policies.
# For more detail on clientAuth options: [ClientAuthType](https://golang.org/pkg/crypto/tls/#ClientAuthType)
[ client_auth_type: <string> | default = "NoClientCert" ]
# CA certificate for client certificate authentication to the server.
[ client_ca_file: <filename> ]
# Minimum TLS version that is acceptable.
[ min_version: <string> | default = "TLS12" ]
# Maximum TLS version that is acceptable.
[ max_version: <string> | default = "TLS13" ]
# List of supported cipher suites for TLS versions up to TLS 1.2. If empty,
# Go default cipher suites are used. Available cipher suites are documented
# in the go documentation:
# https://golang.org/pkg/crypto/tls/#pkg-constants
[ cipher_suites:
[ - <string> ] ]
# prefer_server_cipher_suites controls whether the server selects the
# client's most preferred ciphersuite, or the server's most preferred
# ciphersuite. If true then the server's preference, as expressed in
# the order of elements in cipher_suites, is used.
[ prefer_server_cipher_suites: <bool> | default = true ]
# Elliptic curves that will be used in an ECDHE handshake, in preference
# order. Available curves are documented in the go documentation:
# https://golang.org/pkg/crypto/tls/#CurveID
[ curve_preferences:
[ - <string> ] ]
http_server_config:
# Enable HTTP/2 support. Note that HTTP/2 is only supported with TLS.
# This can not be changed on the fly.
[ http2: <bool> | default = true ]
# 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.

# web package
This package can be used by Prometheus exporters to enable TLS and
authentication.
We actively encourage the community to use this repository, to provide a
consistent experience across the ecosystem.
Developers documentation can be found on
[pkg.go.dev](https://pkg.go.dev/github.com/prometheus/exporter-toolkit/).
