NAME¶
getds - Create a DS record from DNSKEYing information
SYNOPSIS¶
getds <domain>
DESCRIPTION¶
getds will create a DS record from DNSKEYs for the specified DNS domain.
It does this by converting DNSKEYs to DS records using the specified hashing
algorithm. The results can then be passed to upstream DNSSEC-supporting
parents or to DLV registries.
getds will also pull the parent's published DS records and compare them
against the existing keys. It will then list any DS records not published in
the parent, as well as any DS records that are published in the parent but
which don't match an existing key.
OPTIONS¶
getds takes the following options:
- -a ALGORITHMS
- --hash-algorithm algorithm ALGORITHMS
- This option specifies the hash algorithm to use when
converting DNSKEYs to DS records. It may be a comma-separated list if
multiple algorithms are desired. The algorithms to choose from may be
either SHA256 or SHA1.
The default is SHA256,SHA1
- -z
- --print-zsks
- This option causes getds to print ZSK DS records, as
well as KSK records.
- -p
- --dont-check-parent
- Instructs getds to not check the records in the
parent for their published DS records.
- -q
- --quiet
- Produces quiet output with no explanatory headers. In other
words, it only prints the DS records generated from the DNSKEYs.
Note: Running with -q implies -p.
SECURITY CONSIDERATIONS¶
By default,
getds pulls data from the live DNS. If your DNS resolver
isn't configured so that this is pulled securely, then the results can't be
trusted.
