NAMEdane - Generate TLSA/HASTLS DNS records by scanning SSL/TLS sites
SYNTAXdane [-v] [-q] [-h] [-v] [--draft|--rfc] [--sha256] [--sha512] [--full] [--insecure] [--pubkey] [--txt] [--eecert] [--cacert] [-4] [-6] [--axfr] [-n <nameserver>] host1 [host2 ...]] [@nameserver]]
DESCRIPTIONdane 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.
OPTIONS-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.
