Generate tlsa/hastls dns records by scanning ssl/tls sites
dane [-v] [-q] [-h] [-v] [--draft|--rfc] [--sha256] [--sha512] [--full] [--insecure] [--pubkey] [--txt] [--eecert] [--cacert] [-4] [-6] [--axfr] [-n <nameserver>] host1 [host2 ...]] [@nameserver]]
dane generates TLSA/HASTLS records based on the IETF DANE working group proposal. These are currently in draft, so private RRTYPE assignments are used. Records are generated by connecting to the website using SSL and grabbing its (EE) certificate. If the nameserver of the domain allows zone tranfers (AXFR), an entire domain can be processed for all its A/AAAA records.
-n / --nameserver <hostname1>
Use specified nameserver for AXFR query
-q / --quiet
Supress all warnings - useful when scanning lots of host where some do not run SSL
--axfr
Use AXFR. Implies -n nameserver (or @nameserver). Hosts are treated as zones to AXFR.
--tlsa
Output TLSA record from SSL server scan results (default)
--eecert
Output TLSA record format EE certificates (type 1) (default)
--pubkey
Output TLSA record for just the public key (type unassined) (not implemented yet)
--txt
Output Kaminsky style TXT record for (not implemented yet)
--cacert
Output TLSA record for the entire CA chain and EE-cert (not yet implemented)
--sha256
Output TLSA record reference type 1 (SHA256) records (default)
--sha512
Output TLSA record reference type 2 (SHA512) records
--full
Output TLSA record reference type 0 (full cert) records
--draft
Output Unknown Resource Record format with private RRTYPE assignment. This is used while the standard is still in draft form, and for when your nameserver does not (yet) support the new RRTYPE names. This option is the default (if --rfc is not specified) as long as dane is has not be released as RFC.
--rfc
Specify records using the RRTYPE's TLSA (and HASTLA)
--insecure
Continue scanning even if the A/AAAA records could not be validated using DNSSEC
-4
Only use ipv4 networking - do not attempt to connect to AAAA SSL sites
-6
Only use ipv6 networking - do not attempt to connect to A SSL sites
-h / --help
Output help information and exit.
-v / --version
Output version information and exit.
