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
cert. The most common SUBCOMMANDS and flags are:

obtain, install, and renew certificates:
    (default) run   Obtain & install a cert in your current webserver
    certonly        Obtain or renew a cert, but do not install it
    renew           Renew all previously obtained certs that are near expiry
   -d DOMAINS       Comma-separated list of domains to obtain a cert 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 certs interactively, or using shell script hooks

   -n               Run non-interactively
  --test-cert       Obtain a test cert from a staging server
  --dry-run         Test "renew" or "certonly" without saving any certs to disk

manage certificates:
    certificates    Display information about certs 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)
  -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. (default: Ask)
  --cert-name CERTNAME  Certificate name to apply. Only one certificate name
                        can be used per Certbot run. To see certificate names,
                        run 'certbot certificates'. When creating a new
                        certificate, specifies the new certificate's name.
                        (default: None)
  --dry-run             Perform a test run of the client, obtaining test
                        (invalid) certs 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 certs, 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. --renew-hook commands are not called.
                        (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 and plugin. If
                        you wish to hide your server OS version from the Let's
                        Encrypt server, set this to "". (default:
                        CertbotACMEClient/0.12.0 (Ubuntu 16.04.2 LTS)
                        Authenticator/XXX Installer/YYY)

automation:
  Arguments for automating execution & other tweaks

  --keep-until-expiring, --keep, --reinstall
                        If the requested cert matches an existing cert, always
                        keep the existing one until it is due for renewal (for
                        the 'run' subcommand this means reinstall the existing
                        cert). (default: Ask)
  --expand              If an existing cert covers some 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)
  --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)
  -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:
                        False)
  --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)

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) certs; equivalent to --server https://acme-
                        staging.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
                        affects the port Certbot listens on. A conforming ACME
                        server will still attempt to connect on port 443.
                        (default: 443)
  --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)
  --break-my-certs      Be willing to replace or renew valid certs with
                        invalid (testing/staging) certs (default: False)

paths:
  Arguments changing execution paths & servers

  --cert-path CERT_PATH
                        Path to where cert is saved (with auth --csr),
                        installed from, or revoked. (default: None)
  --key-path KEY_PATH   Path to private key for cert installation or
                        revocation (if account key is missing) (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-v01.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
  update_symlinks       Recreate symlinks in your /etc/letsencrypt/live/
                        directory

run:
  Options for obtaining & installing certs

certonly:
  Options for modifying how a cert 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)
  --renew-hook RENEW_HOOK
                        Command to be run in a shell once for each
                        successfully renewed certificate. For this command,
                        the shell variable $RENEWED_LINEAGE will point to the
                        config live subdirectory containing the new certs and
                        keys; the shell variable $RENEWED_DOMAINS will contain
                        a space-delimited list of renewed cert domains
                        (default: None)
  --disable-hook-validation
                        Ordinarily the commands specified for --pre-hook
                        /--post-hook/--renew-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)

certificates:
  List certificates managed by Certbot

delete:
  Options for deleting a certificate

revoke:
  Options for revocation of certs

  --reason {keycompromise,affiliationchanged,superseded,unspecified,cessationofoperation}
                        Specify reason for revoking certificate. (default: 0)

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.
                        (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 cert is deployed

  --fullchain-path FULLCHAIN_PATH
                        Accompanying path to a full certificate chain (cert
                        plus chain). (default: None)

config_changes:
  Options for controlling which changes are displayed

  --num NUM             How many past revisions you want to be 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)

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 are $CERTBOT_DOMAIN which
  contains the domain being authenticated, $CERTBOT_VALIDATION which is the
  validation string, and $CERTBOT_TOKEN which 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.

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:
                        {})
