DNS TLSA RR record (for HTTPS)


#1

I have been trying to find out how to “Generate TLSA Record” for 443 according to this website manual


it is possible via https://www.huque.com/bin/gen_tlsa

But, in my /home/user-data/ssl/ i see:
-rw------- 1 root root 3449 Oct 5 2017 2nddomain.co.uk-20180103-9116b93c.pem
-rw------- 1 root root 3437 Sep 29 2017 3rddomain.cz-20171227-688a4728.pem

lrwxrwxrwx 1 root root 57 May 16 03:01 ssl_certificate.pem -> /home/user-data/ssl/box.domain.name-20180814-a8ae6470.pem
-rw------- 1 root root 1675 Sep 28 2017 ssl_private_key.pem

so for example when I use the certificat from 3rddomain.cz-20171227-688a4728.pem
to generate TLSA Record it shows expired cert for that domain name …

Since I have read somewhere here that @JoshData is rewriting the cert script, could we have TLSA Records automatically generated for all domains instead only for “box.domain.name”, see below?

_25._tcp.box.domain.name TLSA 3 1 1 1a1cca2b952284703c4cfb8f4960c9a49c7443aa1cca4dd0bdad40801aa85a39
Recommended when DNSSEC is enabled. Advertises to mail servers connecting to the box that mandatory encryption should be used.

_443._tcp.box.domain.name TLSA 3 1 1 1a1cca2b952284703c4cfb8f4960c9a49c7443aa1cca4dd0bdad40801aa85a39
Optional. When DNSSEC is enabled, provides out-of-band HTTPS certificate validation for a few web clients that support it.
