certbot script documentation 0.0 3.5 C 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(aqs 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(aqs Subscriber Agreement -m EMAIL Email address for important account notifications options: -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(aqs 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(aqs 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(aqt affect the content of the certificate itself. To see certificate names, run (aqcertbot certificates(aq. When creating a new certificate, specifies the new certificate(aqs 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 (aqcertonly(aq and (aqrenew(aq 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 (ga-v(ga 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(aqs Encrypt server, set this to "". (default: CertbotACMEClient/1.26.0 (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 (aqrun(aq 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(aqs 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) --new-key When renewing or replacing a certificate, generate a new private key, even if --reuse-key is set on the existing certificate. Combining --new-key and --reuse- key will result in the private key being replaced and then reused in future renewals. (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(aqs 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 (aqcertonly(aq subcommand. (default: None) renew: The (aqrenew(aq subcommand will attempt to renew any certificates previously obtained if they are close to expiry, and print a summary of the results. By default, (aqrenew(aq will reuse the plugins and options used to obtain or most recently renew each certificate. You can test whether future renewals will succeed with (ga--dry-run(ga. Individual certificates can be renewed with the (ga--cert-name(ga 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(aqt 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(aqs hook directories during renewal.
