NAME
       danetool - GnuTLS DANE tool

SYNOPSIS
       danetool [-flag [value]]... [--opt-name[[=| ]value]]...

       All arguments must be options.

DESCRIPTION
       Tool to generate and check DNS resource records for the DANE protocol.

OPTIONS
       -d number, --debug=number
	      Enable debugging..  This option takes an integer number as its argument.	The value
	      of number is constrained to being:
		  in the range	0 through 9999

	      Specifies the debug level.

       -V, --verbose
	      More verbose output.  This option may appear an unlimited number of times.

       --infile=file
	      Input file.

       --outfile=string
	      Output file.

       --load-pubkey=string
	      Loads a public key file.

	      This can be either a file or a PKCS #11 URL

       --load-certificate=string
	      Loads a certificate file.

	      This can be either a file or a PKCS #11 URL

       --dlv=string
	      Sets a DLV file.

	      This sets a DLV file to be used for DNSSEC verification.

       --hash=string
	      Hash algorithm to use for signing..

	      Available hash functions are SHA1, RMD160, SHA256, SHA384, SHA512.

       --check=string
	      Check a host's DANE TLSA entry..

	      Obtains the DANE TLSA entry from the given hostname and prints information. Note
	      that the actual certificate of the host has to be provided using --load-certifi-
	      cate.

       --check-ee
	      Check only the end-entity's certificate..

	      Checks the end-entity's certificate only. Trust anchors or CAs are not considered.

       --check-ca
	      Check only the CA's certificate..

	      Checks the trust anchor's and CA's certificate only. End-entities are not consid-
	      ered.

       --insecure
	      Do not verify any DNSSEC signature..

	      Ignores any DNSSEC signature verification results.

       --local-dns, --no-local-dns
	      Use the local DNS server for DNSSEC resolving..  The no-local-dns form will disable
	      the option.

	      This option will use the local DNS server for DNSSEC.  This is disabled by default
	      due to many servers not allowing DNSSEC.

       --inder, --no-inder
	      Use DER format for input certificates and private keys..	The no-inder form will
	      disable the option.

	      The input files will be assumed to be in DER or RAW format.  Unlike options that in
	      PEM input would allow multiple input data (e.g. multiple certificates), when read-
	      ing in DER format a single data structure is read.

       --inraw
	      This is an alias for the --inder option.

       --tlsa-rr
	      Print the DANE RR data on a certificate or public key.  This option must appear in
	      combination with the following options: host.

	      This command prints the DANE RR data needed to enable DANE on a DNS server.

       --host=hostname
	      Specify the hostname to be used in the DANE RR.

	      This command sets the hostname for the DANE RR.

       --proto=protocol
	      The protocol set for DANE data (tcp, udp etc.).

	      This command specifies the protocol for the service set in the DANE data.

       --port=number
	      Specify the port number for the DANE data..  This option takes an integer number as
	      its argument.

       --ca   Whether the provided certificate or public key is a Certificate Authority..

	      Marks the DANE RR as a CA certificate if specified.

       --x509 Use the hash of the X.509 certificate, rather than the public key..

	      This option forces the generated record to contain the hash of the full X.509 cer-
	      tificate. By default only the hash of the public key is used.

       --local
	      This is an alias for the --domain option.

       --domain, --no-domain
	      The provided certificate or public key is issued by the local domain..  The
	      no-domain form will disable the option.  This option is enabled by default.

	      DANE distinguishes certificates and public keys offered via the DNSSEC to trusted
	      and local entities. This flag indicates that this is a domain-issued certificate,
	      meaning that there could be no CA involved.

       -h, --help
	      Display usage information and exit.

       -!, --more-help
	      Pass the extended usage information through a pager.

       -v [{v|c|n}], --version[={v|c|n}]
	      Output version of program and exit.  The default mode is `v', a simple version.
	      The `c' mode will print copyright information and `n' will print the full copyright
	      notice.

EXAMPLES
       DANE TLSA RR generation

       To create a DANE TLSA resource record for a certificate (or public key) that was issued
       localy and may or may not be signed by a CA use the following command.
	   $ danetool --tlsa-rr --host www.example.com --load-certificate cert.pem

       To create a DANE TLSA resource record for a CA signed certificate, which will be marked as
       such use the following command.
	   $ danetool --tlsa-rr --host www.example.com --load-certificate cert.pem   --no-domain

       The former is useful to add in your DNS entry even if your certificate is signed by a CA.
       That way even users who do not trust your CA will be able to verify your certificate using
       DANE.

       In order to create a record for the CA signer of your certificate use the following.
	   $ danetool --tlsa-rr --host www.example.com --load-certificate cert.pem   --ca --no-domain

       To read a server's DANE TLSA entry, use:
	   $ danetool --check www.example.com --proto tcp --port 443

       To verify a server's DANE TLSA entry, use:
	   $ danetool --check www.example.com --proto tcp --port 443 --load-certificate chain.pem

EXIT STATUS
       One of the following exit values will be returned:

       0 (EXIT_SUCCESS)
	      Successful program execution.

       1 (EXIT_FAILURE)
	      The operation failed or the command syntax was not valid.

       70 (EX_SOFTWARE)
	      libopts had an internal operational error.  Please report it to autogen-
	      users@lists.sourceforge.net.  Thank you.
