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.

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
| Aufgabe | Befehl |
|---|---|
| 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
| Aufgabe | Befehl |
|---|---|
| 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
| Unix | GNU | Beschreibung |
|---|---|---|
| -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)

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)
certificates
List certificates managed by Certbot
delete
Options for deleting a certificate
revoke
Options for revocation of certificates
--reason {unspecified,keycompromise,affiliationchanged,superseded,cessationofoperation}
Specify reason for revoking certificate. (default:
unspecified)
--delete-after-revoke
Delete certificates after revoking them, along with
all previous and later versions of those certificates.
(default: None)
--no-delete-after-revoke
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)
register
Options for account registration
--register-unsafely-without-email
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)
--no-eff-email Don't share your e-mail address with EFF (default:
None)
update_account
Options for account modification
unregister
Options for account deactivation.
--account ACCOUNT_ID Account ID to use (default: None)
install
Options for modifying how a certificate is deployed
rollback
Options for rolling back server configuration changes
--checkpoints N Revert configuration N number of checkpoints.
(default: 1)
plugins
Options for the "plugins" subcommand
--init Initialize plugins. (default: False) --prepare Initialize and prepare plugins. (default: False) --authenticators Limit to authenticator plugins only. (default: None) --installers Limit to installer plugins only. (default: None)
update_symlinks
Recreates certificate and key symlinks in /etc/letsencrypt/live, if you changed them by hand or edited a renewal configuration file
enhance
Helps to harden the TLS configuration by adding security enhancements to already existing configuration.
show_account
Options useful for the "show_account" subcommand:
plugins
Plugin Selection: Certbot client supports an extensible plugins architecture. See 'certbot plugins' for a list of all installed plugins and their names. You can force a particular plugin by setting options provided below. Running --help <plugin_name> will list flags specific to that plugin.

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.

--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:
{})
