To get a PEM & TLSA DNS record that will work for DANE SSL/TLS, do the following
- Edit the file
config
and put in the values you want (seeconfig.example
) - run
./make_key
This will give you two files - a PEM & a TXT of the DNS TLSA records. They will be prefixed by the host name
Give the PEM to your SSL/TLS server as both the certificate & key file, & put the DNS record in your server's parent DNS zone file (DNSSEC signed).
e.g for nginx
ssl_certificate /etc/nginx/ca/dane.txt.pem;
ssl_certificate_key /etc/nginx/ca/dane.txt.pem;
If you want to keep multiple copies of different config
files, you can give them different names, then run
./make_key <config-file>
You can try out the example, if you wish - but it will only be useful if you happen to own the domain name example.txt
./make_key config.example
