@subheading DANE TLSA RR generation

To create a DANE TLSA resource record for a certificate (or public key) 
that was issued locally and may or may not be signed by a CA use the following command.
@example
$ danetool --tlsa-rr --host www.example.com --load-certificate cert.pem
@end example

To create a DANE TLSA resource record for a CA signed certificate, which will
be marked as such use the following command.
@example
$ danetool --tlsa-rr --host www.example.com --load-certificate cert.pem \
  --no-domain
@end example

The former is useful to add in your DNS entry even if your certificate is signed 
by a CA. 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 an HTTPS server's DANE TLSA entry, use:
@example
$ danetool --check www.example.com --proto tcp --port 443 --load-certificate chain.pem
@end example

To verify an SMTP server's DANE TLSA entry, use:
@example
$ danetool --check www.example.com --proto tcp --starttls-proto=smtp --load-certificate chain.pem
@end example
