@subheading DANE TLSA RR generation

To create a DANE TLSA resource record for a CA signed certificate use the following commands.

@example
$ danetool --tlsa-rr --host www.example.com --load-certificate cert.pem
@end example

For a self signed certificate use:
@example
$ danetool --tlsa-rr --host www.example.com --load-certificate cert.pem \
  --local
@end example

The latter 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 signer of your certificate use:
@example
$ danetool --tlsa-rr --host www.example.com --load-certificate cert.pem \
  --ca
@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
