vendor/github.com/prometheus/exporter-toolkit/https/README.md

-# 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.
