       certbot - certbot script documentation

          usage:
            certbot [SUBCOMMAND] [options] [-d DOMAIN] [-d DOMAIN] ...

          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:
              (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-path)
              delete          Delete a certificate

          manage your account with Let's Encrypt:
              register        Create a Let's Encrypt ACME account
            --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:
                                  -2)
            --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)
            --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 (default: False)
            --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 "tls-
                                  sni-01,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: [])
            --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/0.26.1
                                  (certbot(-auto); 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)
            --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)
            --os-packages-only    (certbot-auto only) install OS package dependencies
                                  and then stop (default: False)
            --no-self-upgrade     (certbot-auto only) prevent the certbot-auto script
                                  from upgrading itself to newer released versions
                                  (default: Upgrade automatically)
            --no-bootstrap        (certbot-auto only) prevent the certbot-auto script
                                  from installing OS-level dependencies (default: Prompt
                                  to install OS-wide dependencies, but exit if the user
                                  says 'No')
            -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)
            --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: Ask)
            --no-redirect         Do not automatically redirect all HTTP traffic to
                                  HTTPS for the newly authenticated vhost. (default:
                                  Ask)
            --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, and allow certbot-
                                  auto execution on experimental platforms (default:
                                  False)
            --no-verify-ssl       Disable verification of the ACME server's certificate.
                                  (default: False)
            --tls-sni-01-port TLS_SNI_01_PORT
                                  Port used during tls-sni-01 challenge. This only

                                  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: )
            --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 auth --csr),
                                  installed from, or revoked. (default: None)
            --key-path KEY_PATH   Path to private key for certificate installation or

          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
            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 all certificates (or more
            precisely, certificate lineages) you have previously obtained if they are
            close to expiry, and print a summary of the results. By default, 'renew'
            will reuse the options used to create obtain or most recently successfully
            renew each certificate lineage. You can try it with `--dry-run` first. For
            more fine-grained control, you can renew individual lineages with the
            `certonly` subcommand. 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. (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 & modification

            --register-unsafely-without-email
                                  Specifying this flag enables registering an account
                                  with no email address. This is strongly discouraged,
                                  because in the event of key loss or account compromise
                                  you will irrevocably lose access to your account. You
                                  will also be unable to receive notice about impending
                                  expiration or revocation of your certificates. Updates
                                  to the Subscriber Agreement will still affect you, and
                                  will be effective 14 days after posting an update to
                                  the web site. (default: False)
            --update-registration
                                  With the register verb, indicates that details
                                  associated with an existing registration, such as the
                                  e-mail address, should be updated, rather than
                                  registering a new account. (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)

          unregister:
            Options for account deactivation.

            --account ACCOUNT_ID  Account ID to use (default: None)

          install:
            Options for modifying how a certificate is deployed

          config_changes:
            Options for controlling which changes are displayed

                                  (default: None)

          rollback:
            Options for rolling back server configuration changes

            --checkpoints N       Revert configuration N number of checkpoints.
                                  (default: 1)

          plugins:
            Options for 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.

          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. When performing a TLS-
            SNI-01 challenge, $CERTBOT_SNI_DOMAIN will contain the SNI name for which
            the ACME server expects to be presented with the self-signed certificate
            located at $CERTBOT_CERT_PATH. The secret key needed to complete the TLS
            handshake is located at $CERTBOT_KEY_PATH. 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.

            --manual-auth-hook MANUAL_AUTH_HOOK

                                  Path or command to execute for the cleanup script
                                  (default: None)
            --manual-public-ip-logging-ok
                                  Automatically allows public IP logging (default: Ask)

            --nginx-ctl NGINX_CTL
                                  Path to the 'nginx' binary, used for 'configtest' and
                                  retrieving nginx version number. (default: nginx)

          null:
            Null Installer

          standalone:
            Spin up a temporary webserver

          webroot:
            Place files in webroot directory

            --webroot-path WEBROOT_PATH, -w WEBROOT_PATH
                                  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:
                                  {})
