+deploy_challenge() {
+ local DOMAIN="${1}" TOKEN_FILENAME="${2}" TOKEN_VALUE="${3}"
+
+ # This hook is called once for every domain that needs to be
+ # validated, including any alternative names you may have listed.
+ #
+ # Parameters:
+ # - DOMAIN
+ # The domain name (CN or subject alternative name) being
+ # validated.
+ # - TOKEN_FILENAME
+ # The name of the file containing the token to be served for HTTP
+ # validation. Should be served by your web server as
+ # /.well-known/acme-challenge/${TOKEN_FILENAME}.
+ # - TOKEN_VALUE
+ # The token value that needs to be served for validation. For DNS
+ # validation, this is what you want to put in the _acme-challenge
+ # TXT record. For HTTP validation it is the value that is expected
+ # be found in the $TOKEN_FILENAME file.
+
+ # Simple example: Use nsupdate with local named
+ # printf 'server 127.0.0.1\nupdate add _acme-challenge.%s 300 IN TXT "%s"\nsend\n' "${DOMAIN}" "${TOKEN_VALUE}" | nsupdate -k /var/run/named/session.key

+ #
+ # The parameters are the same as for deploy_challenge.

+ # Simple example: Use nsupdate with local named
+ # printf 'server 127.0.0.1\nupdate delete _acme-challenge.%s TXT "%s"\nsend\n' "${DOMAIN}" "${TOKEN_VALUE}" | nsupdate -k /var/run/named/session.key

+ local KEYFILE="${1}" CERTFILE="${2}" FULLCHAINFILE="${3}" CHAINFILE="${4}" REQUESTFILE="${5}"
+
+ # This hook is called after the certificates have been created but before
+ # they are symlinked. This allows you to sync the files to disk to prevent
+ # creating a symlink to empty files on unexpected system crashes.
+ #
+ # This hook is not intended to be used for further processing of certificate
+ # files, see deploy_cert for that.
+ #
+ # Parameters:
+ # - KEYFILE
+ # The path of the file containing the private key.
+ # - CERTFILE
+ # The path of the file containing the signed certificate.
+ # - FULLCHAINFILE
+ # The path of the file containing the full certificate chain.
+ # - CHAINFILE
+ # The path of the file containing the intermediate certificate(s).
+ # - REQUESTFILE
+ # The path of the file containing the certificate signing request.
+
+ # Simple example: sync the files before symlinking them
+ # sync "${KEYFILE}" "${CERTFILE}" "${FULLCHAINFILE}" "${CHAINFILE}" "${REQUESTFILE}"
+ {{ dehydrated_sync_cert_hook }}

+ # - KEYFILE

+ # - TIMESTAMP
+ # Timestamp when the specified certificate was created.

+ # - DOMAIN
+ # The primary domain name, i.e. the certificate common

+ # - RESPONSE
+ # The response that the verification server returned

+ #
+ # Parameters:
+ # - STATUSCODE
+ # The HTML status code that originated the error.
+ # - REASON
+ # The specified reason for the error.
+ # - REQTYPE
+ # The kind of request that was made (GET, POST...)
+ # - HEADERS
+ # HTTP headers returned by the CA
+
+ # Simple example: Send mail to root

+ # The output should be just the certificate signing request formatted as PEM.

+ # Parameters:
+ # - DOMAIN
+ # The primary domain as specified in domains.txt. This does not need to
+ # match with the domains in the CSR, it's basically just the directory name.
+ # - CERTDIR
+ # Certificate output directory for this particular certificate. Can be used
+ # for storing additional files.
+ # - ALTNAMES
+ # All domain names for the current certificate as specified in domains.txt.
+ # Again, this doesn't need to match with the CSR, it's just there for convenience.
+
+ # Simple example: Look for pre-generated CSRs
+ # if [ -e "${CERTDIR}/pre-generated.csr" ]; then
