NAME

       dane - Generate TLSA/HASTLS DNS records by scanning SSL/TLS sites

SYNTAX

       dane [-v] [-q] [-h] [-v] [--draft|--rfc] [--sha256] [--sha512] [--full] [--insecure] [--pubkey] [--txt] [--eecert] [--cacert] [-4] [-6]
       [--axfr] [-n <nameserver>] host1 [host2 ...]] [@nameserver]]

DESCRIPTION

       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.

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.
