danetool

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

              Checks the trust anchor's and CA's certificate only. End-enti-
              ties are not considered.

       --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 reading in DER format a sin-
              gle 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.


       --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:
