That way even users who do not trust your CA will be able to verify your certificate using DANE. In order to create a record for the CA signer of your certificate use the following. @example $ danetool --tlsa-rr --host www.example.com --load-certificate cert.pem \ --ca --no-domain @end example To read a server's DANE TLSA entry, use: @example $ danetool --check www.example.com --proto tcp --port 443 @end example To verify a server's DANE TLSA entry, use: @example $ danetool --check www.example.com --proto tcp --port 443 --load-certificate chain.pem @end example _EOT_; };
