netcup DNS Authenticator plugin for Certbot
Project description
netcup DNS Authenticator plugin for certbot.
This plugin automates the process of completing a dns-01 challenge by creating, and subsequently removing, TXT records using the netcup CCP API.
Based on the netcup CCP API using nc_dnsapi.
Forked from certbot-dns-cloudflare.
Named Arguments
--certbot-dns-netcup:dns-netcup-credentials |
netcup credentials INI file. (Required) |
--certbot-dns-netcup:dns-netcup-propagation-seconds |
The number of seconds to wait for DNS to propagate before asking the ACME server to verify the DNS record. (Default: 10) |
Note that the seemingly redundant certbot-dns-netcup: prefix is imposed by certbot for external plugins.
Credentials
Use of this plugin requires a configuration file containing netcup API credentials, obtained from your netcup account page. See also the CCP API documentation.
An example credentials.ini file:
certbot_dns_netcup:dns_netcup_customer_id = 123456
certbot_dns_netcup:dns_netcup_api_key = 0123456789abcdef0123456789abcdef01234567
certbot_dns_netcup:dns_netcup_api_password = abcdef0123456789abcdef01234567abcdef0123
The path to this file can be provided interactively or using the --certbot-dns-netcup:dns-netcup-credentials command-line argument. Certbot records the path to this file for use during renewal, but does not store the file’s contents.
CAUTION: You should protect these API credentials as you would the password to your netcup account. Users who can read this file can use these credentials to issue arbitrary API calls on your behalf. Users who can cause Certbot to run using these credentials can complete a dns-01 challenge to acquire new certificates or revoke existing certificates for associated domains, even if those domains aren’t being managed by this server.
Certbot will emit a warning if it detects that the credentials file can be accessed by other users on your system. The warning reads “Unsafe permissions on credentials configuration file”, followed by the path to the credentials file. This warning will be emitted each time Certbot uses the credentials file, including for renewal, and cannot be silenced except by addressing the issue (e.g., by using a command like chmod 600 to restrict access to the file).
Examples
To acquire a single certificate for both example.com and www.example.com, waiting 900 seconds for DNS propagation:
certbot certonly \\
--authenticator certbot-dns-netcup:dns-netcup \\
--certbot-dns-netcup:dns-netcup-credentials ~/.secrets/certbot/netcup.ini \\
--certbot-dns-netcup:dns-netcup-propagation-seconds 900 \\
-d example.com \\
-d www.example.com
