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:
0 (EXIT_SUCCESS)
