Certbot

topic kurze Beschreibung

Beschreibung

Das Ziel von Certbot, Let's Encrypt und des ACME-Protokolls (Automated Certificate Management Environment) ist es, einen HTTPS-Server einzurichten und ihm automatisch, ohne menschliches Eingreifen, ein für Browser vertrauenswürdiges Zertifikat zu beschaffen. Dies geschieht durch das Ausführen eines Agenten zur Zertifikatsverwaltung auf dem Webserver.

Dieser Agent wird verwendet, um:

• der »Let's Encrypt«-Zertifizierungsstelle automatisch zu beweisen, dass Sie die Website kontrollieren
• ein für Browser vertrauenswürdiges Zertifikat zu beschaffen und es auf Ihrem Webserver einzurichten
• den Ablauf Ihres Zertifikats zu verfolgen und es zu erneuern
• das Zertifikat zu widerrufen, wenn das jemals notwendig wird

Dieses Paket enthält das Hauptprogramm sowie die selbstständigen und manuellen Authentifizierungsprogramme.

Installation

# apt install certbot

Syntax

# certbot [SUBCOMMAND] [options] [-d DOMAIN] [-d DOMAIN] ...

Anwendungen

Certbot can obtain and install HTTPS/TLS/SSL certificates. By default, it will attempt to use a webserver both for obtaining and installing the certificate. The most common SUBCOMMANDS and flags are:

obtain, install, and renew certificates

Befehl	Beschreibung
(default) run	Obtain & install a certificate in your current webserver
certonly	Obtain or renew a certificate, but do not install it
renew	Renew all previously obtained certificates that are near expiry
enhance	Add security enhancements to your existing configuration
-d DOMAINS	Comma-separated list of domains to obtain a certificate for
--apache	Use the Apache plugin for authentication & installation
--standalone	Run a standalone webserver for authentication
--nginx	Use the Nginx plugin for authentication & installation
--webroot	Place files in a server's webroot folder for authentication
--manual	Obtain certificates interactively, or using shell script hooks
-n	Run non-interactively
--test-cert	Obtain a test certificate from a staging server
--dry-run	Test "renew" or "certonly" without saving any certificates to disk

manage certificates

   certificates    Display information about certificates you have from Certbot
   revoke          Revoke a certificate (supply --cert-name or --cert-path)
   delete          Delete a certificate (supply --cert-name)

manage your account

   register        Create an ACME account
   unregister      Deactivate an ACME account
   update_account  Update an ACME account
   show_account    Display account details
 --agree-tos       Agree to the ACME server's Subscriber Agreement
  -m EMAIL         Email address for important account notifications

optional arguments

 -h, --help            show this help message and exit
 -c CONFIG_FILE, --config CONFIG_FILE
                       path to config file (default: /etc/letsencrypt/cli.ini
                       and ~/.config/letsencrypt/cli.ini)
 -v, --verbose         This flag can be used multiple times to incrementally
                       increase the verbosity of output, e.g. -vvv. (default:
                       0)
 --max-log-backups MAX_LOG_BACKUPS
                       Specifies the maximum number of backup logs that
                       should be kept by Certbot's built in log rotation.
                       Setting this flag to 0 disables log rotation entirely,
                       causing Certbot to always append to the same log file.
                       (default: 1000)
 -n, --non-interactive, --noninteractive
                       Run without ever asking for user input. This may
                       require additional command line flags; the client will
                       try to explain which ones are required if it finds one
                       missing (default: False)
 --force-interactive   Force Certbot to be interactive even if it detects
                       it's not being run in a terminal. This flag cannot be
                       used with the renew subcommand. (default: False)
 -d DOMAIN, --domains DOMAIN, --domain DOMAIN
                       Domain names to apply. For multiple domains you can
                       use multiple -d flags or enter a comma separated list
                       of domains as a parameter. The first domain provided
                       will be the subject CN of the certificate, and all
                       domains will be Subject Alternative Names on the
                       certificate. The first domain will also be used in
                       some software user interfaces and as the file paths
                       for the certificate and related material unless
                       otherwise specified or you already have a certificate
                       with the same name. In the case of a name collision it
                       will append a number like 0001 to the file path name.
                       (default: Ask)
 --eab-kid EAB_KID     Key Identifier for External Account Binding (default:
                       None)
 --eab-hmac-key EAB_HMAC_KEY
                       HMAC key for External Account Binding (default: None)
 --cert-name CERTNAME  Certificate name to apply. This name is used by
                       Certbot for housekeeping and in file paths; it doesn't
                       affect the content of the certificate itself. To see
                       certificate names, run 'certbot certificates'. When
                       creating a new certificate, specifies the new
                       certificate's name. (default: the first provided
                       domain or the name of an existing certificate on your
                       system for the same domains)
 --dry-run             Perform a test run of the client, obtaining test
                       (invalid) certificates but not saving them to disk.
                       This can currently only be used with the 'certonly'
                       and 'renew' subcommands. Note: Although --dry-run
                       tries to avoid making any persistent changes on a
                       system, it is not completely side-effect free: if used
                       with webserver authenticator plugins like apache and
                       nginx, it makes and then reverts temporary config
                       changes in order to obtain test certificates, and
                       reloads webservers to deploy and then roll back those
                       changes. It also calls --pre-hook and --post-hook
                       commands if they are defined because they may be
                       necessary to accurately simulate renewal. --deploy-
                       hook commands are not called. (default: False)
 --debug-challenges    After setting up challenges, wait for user input
                       before submitting to CA. When used in combination with
                       the `-v` option, the challenge URLs or FQDNs and their
                       expected return values are shown. (default: False)
 --preferred-chain PREFERRED_CHAIN
                       Set the preferred certificate chain. If the CA offers
                       multiple certificate chains, prefer the chain whose
                       topmost certificate was issued from this Subject
                       Common Name. If no match, the default offered chain
                       will be used. (default: None)
 --preferred-challenges PREF_CHALLS
                       A sorted, comma delimited list of the preferred
                       challenge to use during authorization with the most
                       preferred challenge listed first (Eg, "dns" or
                       "http,dns"). Not all plugins support all challenges.
                       See https://certbot.eff.org/docs/using.html#plugins
                       for details. ACME Challenges are versioned, but if you
                       pick "http" rather than "http-01", Certbot will select
                       the latest version automatically. (default: [])
 --issuance-timeout ISSUANCE_TIMEOUT
                       This option specifies how long (in seconds) Certbot
                       will wait for the server to issue a certificate.
                       (default: 90)
 --user-agent USER_AGENT
                       Set a custom user agent string for the client. User
                       agent strings allow the CA to collect high level
                       statistics about success rates by OS, plugin and use
                       case, and to know when to deprecate support for past
                       Python versions and flags. If you wish to hide this
                       information from the Let's Encrypt server, set this to
                       "". (default: CertbotACMEClient/1.24.0 (certbot;
                       OS_NAME OS_VERSION) Authenticator/XXX Installer/YYY
                       (SUBCOMMAND; flags: FLAGS) Py/major.minor.patchlevel).
                       The flags encoded in the user agent are: --duplicate,
                       --force-renew, --allow-subset-of-names, -n, and
                       whether any hooks are set.
 --user-agent-comment USER_AGENT_COMMENT
                       Add a comment to the default user agent string. May be
                       used when repackaging Certbot or calling it from
                       another tool to allow additional statistical data to
                       be collected. Ignored if --user-agent is set.
                       (Example: Foo-Wrapper/1.0) (default: None)

automation

 Flags for automating execution & other tweaks

 --keep-until-expiring, --keep, --reinstall
                       If the requested certificate matches an existing
                       certificate, always keep the existing one until it is
                       due for renewal (for the 'run' subcommand this means
                       reinstall the existing certificate). (default: Ask)
 --expand              If an existing certificate is a strict subset of the
                       requested names, always expand and replace it with the
                       additional names. (default: Ask)
 --version             show program's version number and exit
 --force-renewal, --renew-by-default
                       If a certificate already exists for the requested
                       domains, renew it now, regardless of whether it is
                       near expiry. (Often --keep-until-expiring is more
                       appropriate). Also implies --expand. (default: False)
 --renew-with-new-domains
                       If a certificate already exists for the requested
                       certificate name but does not match the requested
                       domains, renew it now, regardless of whether it is
                       near expiry. (default: False)
 --reuse-key           When renewing, use the same private key as the
                       existing certificate. (default: False)
 --no-reuse-key        When renewing, do not use the same private key as the
                       existing certificate. Not reusing private keys is the
                       default behavior of Certbot. This option may be used
                       to unset --reuse-key on an existing certificate.
                       (default: False)
 --allow-subset-of-names
                       When performing domain validation, do not consider it
                       a failure if authorizations can not be obtained for a
                       strict subset of the requested domains. This may be
                       useful for allowing renewals for multiple domains to
                       succeed even if some domains no longer point at this
                       system. This option cannot be used with --csr.
                       (default: False)
 --agree-tos           Agree to the ACME Subscriber Agreement (default: Ask)
 --duplicate           Allow making a certificate lineage that duplicates an
                       existing one (both can be renewed in parallel)
                       (default: False)
 -q, --quiet           Silence all output except errors. Useful for
                       automation via cron. Implies --non-interactive.
                       (default: False)

security

 Security parameters & server settings

 --rsa-key-size N      Size of the RSA key. (default: 2048)
 --key-type {rsa,ecdsa}
                       Type of generated private key. Only *ONE* per
                       invocation can be provided at this time. (default:
                       rsa)
 --elliptic-curve N    The SECG elliptic curve name to use. Please see RFC
                       8446 for supported values. (default: secp256r1)
 --must-staple         Adds the OCSP Must Staple extension to the
                       certificate. Autoconfigures OCSP Stapling for
                       supported setups (Apache version >= 2.3.3 ). (default:
                       False)
 --redirect            Automatically redirect all HTTP traffic to HTTPS for
                       the newly authenticated vhost. (default: redirect
                       enabled for install and run, disabled for enhance)
 --no-redirect         Do not automatically redirect all HTTP traffic to
                       HTTPS for the newly authenticated vhost. (default:
                       redirect enabled for install and run, disabled for
                       enhance)
 --hsts                Add the Strict-Transport-Security header to every HTTP
                       response. Forcing browser to always use SSL for the
                       domain. Defends against SSL Stripping. (default: None)
 --uir                 Add the "Content-Security-Policy: upgrade-insecure-
                       requests" header to every HTTP response. Forcing the
                       browser to use https:// for every http:// resource.
                       (default: None)
 --staple-ocsp         Enables OCSP Stapling. A valid OCSP response is
                       stapled to the certificate that the server offers
                       during TLS. (default: None)
 --strict-permissions  Require that all configuration files are owned by the
                       current user; only needed if your config is somewhere
                       unsafe like /tmp/ (default: False)
 --auto-hsts           Gradually increasing max-age value for HTTP Strict
                       Transport Security security header (default: False)

testing

 The following flags are meant for testing and integration purposes only.

 --test-cert, --staging
                       Use the staging server to obtain or revoke test
                       (invalid) certificates; equivalent to --server
                       https://acme-staging-v02.api.letsencrypt.org/directory
                       (default: False)
 --debug               Show tracebacks in case of errors (default: False)
 --no-verify-ssl       Disable verification of the ACME server's certificate.
                       (default: False)
 --http-01-port HTTP01_PORT
                       Port used in the http-01 challenge. This only affects
                       the port Certbot listens on. A conforming ACME server
                       will still attempt to connect on port 80. (default:
                       80)
 --http-01-address HTTP01_ADDRESS
                       The address the server listens to during http-01
                       challenge. (default: )
 --https-port HTTPS_PORT
                       Port used to serve HTTPS. This affects which port
                       Nginx will listen on after a LE certificate is
                       installed. (default: 443)
 --break-my-certs      Be willing to replace or renew valid certificates with
                       invalid (testing/staging) certificates (default:
                       False)

paths

 Flags for changing execution paths & servers

 --cert-path CERT_PATH
                       Path to where certificate is saved (with certonly
                       --csr), installed from, or revoked (default: None)
 --key-path KEY_PATH   Path to private key for certificate installation or
                       revocation (if account key is missing) (default: None)
 --fullchain-path FULLCHAIN_PATH
                       Accompanying path to a full certificate chain
                       (certificate plus chain). (default: None)
 --chain-path CHAIN_PATH
                       Accompanying path to a certificate chain. (default:
                       None)
 --config-dir CONFIG_DIR
                       Configuration directory. (default: /etc/letsencrypt)
 --work-dir WORK_DIR   Working directory. (default: /var/lib/letsencrypt)
 --logs-dir LOGS_DIR   Logs directory. (default: /var/log/letsencrypt)
 --server SERVER       ACME Directory Resource URI. (default:
                       https://acme-v02.api.letsencrypt.org/directory)

manage

 Various subcommands and flags are available for managing your
 certificates:

 certificates          List certificates managed by Certbot
 delete                Clean up all files related to a certificate
 renew                 Renew all certificates (or one specified with --cert-
                       name)
 revoke                Revoke a certificate specified with --cert-path or
                       --cert-name
 update_symlinks       Recreate symlinks in your /etc/letsencrypt/live/
                       directory

run

 Options for obtaining & installing certificates

certonly

 Options for modifying how a certificate is obtained

 --csr CSR             Path to a Certificate Signing Request (CSR) in DER or
                       PEM format. Currently --csr only works with the
                       'certonly' subcommand. (default: None)

renew

 The 'renew' subcommand will attempt to renew any certificates previously
 obtained if they are close to expiry, and print a summary of the results.
 By default, 'renew' will reuse the plugins and options used to obtain or
 most recently renew each certificate. You can test whether future renewals
 will succeed with `--dry-run`. Individual certificates can be renewed with
 the `--cert-name` option. Hooks are available to run commands before and
 after renewal; see https://certbot.eff.org/docs/using.html#renewal for
 more information on these.

 --pre-hook PRE_HOOK   Command to be run in a shell before obtaining any
                       certificates. Intended primarily for renewal, where it
                       can be used to temporarily shut down a webserver that
                       might conflict with the standalone plugin. This will
                       only be called if a certificate is actually to be
                       obtained/renewed. When renewing several certificates
                       that have identical pre-hooks, only the first will be
                       executed. (default: None)
 --post-hook POST_HOOK
                       Command to be run in a shell after attempting to
                       obtain/renew certificates. Can be used to deploy
                       renewed certificates, or to restart any servers that
                       were stopped by --pre-hook. This is only run if an
                       attempt was made to obtain/renew a certificate. If
                       multiple renewed certificates have identical post-
                       hooks, only one will be run. (default: None)
 --deploy-hook DEPLOY_HOOK
                       Command to be run in a shell once for each
                       successfully issued certificate. For this command, the
                       shell variable $RENEWED_LINEAGE will point to the
                       config live subdirectory (for example,
                       "/etc/letsencrypt/live/example.com") containing the
                       new certificates and keys; the shell variable
                       $RENEWED_DOMAINS will contain a space-delimited list
                       of renewed certificate domains (for example,
                       "example.com www.example.com" (default: None)
 --disable-hook-validation
                       Ordinarily the commands specified for --pre-
                       hook/--post-hook/--deploy-hook will be checked for
                       validity, to see if the programs being run are in the
                       $PATH, so that mistakes can be caught early, even when
                       the hooks aren't being run just yet. The validation is
                       rather simplistic and fails if you use more advanced
                       shell constructs, so you can use this switch to
                       disable it. (default: False)
 --no-directory-hooks  Disable running executables found in Certbot's hook
                       directories during renewal. (default: False)
 --disable-renew-updates
                       Disable automatic updates to your server configuration
                       that would otherwise be done by the selected installer
                       plugin, and triggered when the user executes "certbot
                       renew", regardless of if the certificate is renewed.
                       This setting does not apply to important TLS
                       configuration updates. (default: False)
 --no-autorenew        Disable auto renewal of certificates. (default: True)

                       Do not delete certificates after revoking them. This
                       option should be used with caution because the 'renew'
                       subcommand will attempt to renew undeleted revoked
                       certificates. (default: None)

                       Specifying this flag enables registering an account
                       with no email address. This is strongly discouraged,
                       because you will be unable to receive notice about
                       impending expiration or revocation of your
                       certificates or problems with your Certbot
                       installation that will lead to failure to renew.
                       (default: False)
 -m EMAIL, --email EMAIL
                       Email used for registration and recovery contact. Use
                       comma to register multiple emails, ex:
                       u1@example.com,u2@example.com. (default: Ask).
 --eff-email           Share your e-mail address with EFF (default: None)

manual

 Authenticate through manual configuration or custom shell scripts. When
 using shell scripts, an authenticator script must be provided. The
 environment variables available to this script depend on the type of
 challenge. $CERTBOT_DOMAIN will always contain the domain being
 authenticated. For HTTP-01 and DNS-01, $CERTBOT_VALIDATION is the
 validation string, and $CERTBOT_TOKEN is the filename of the resource
 requested when performing an HTTP-01 challenge. An additional cleanup
 script can also be provided and can use the additional variable
 $CERTBOT_AUTH_OUTPUT which contains the stdout output from the auth
 script. For both authenticator and cleanup script, on HTTP-01 and DNS-01
 challenges, $CERTBOT_REMAINING_CHALLENGES will be equal to the number of
 challenges that remain after the current one, and $CERTBOT_ALL_DOMAINS
 contains a comma-separated list of all domains that are challenged for the
 current certificate.

                       public_html / webroot path. This can be specified
                       multiple times to handle different domains; each
                       domain will have the webroot path that preceded it.
                       For instance: `-w /var/www/example -d example.com -d
                       www.example.com -w /var/www/thing -d thing.net -d
                       m.thing.net` (default: Ask)
 --webroot-map WEBROOT_MAP
                       JSON dictionary mapping domains to webroot paths; this
                       implies -d for each entry. You may need to escape this
                       from your shell. E.g.: --webroot-map
                       '{"eg1.is,m.eg1.is":"/www/eg1/", "eg2.is":"/www/eg2"}'
                       This option is merged with, but takes precedence over,
                       -w / -d entries. At present, if you put webroot-map in
                       a config file, it needs to be on a single line, like:
                       webroot-map = {"example.com":"/var/www"}. (default:
                       {})
