## DESCRIPTION

`dnssec-checkds` verifies the correctness of Delegation Signer (DS) resource records for keys in a specified zone.

## OPTIONS

-a algorithm

  Specify a digest algorithm to use when converting the zone's DNSKEY records to expected DS records. This option can be repeated, so that multiple records are checked for each DNSKEY record.

  The algorithm must be one of SHA-1, SHA-256, or SHA-384. These values are case insensitive, and the hyphen may be omitted. If no algorithm is specified, the default is SHA-256.

-f file

  If a `file` is specified, then the zone is read from that file to find the DNSKEY records. If not, then the DNSKEY records for the zone are looked up in the DNS.

-s file

  Specifies a prepared dsset file, such as would be generated by `dnssec-signzone`, to use as a source for the DS RRset instead of querying the parent.

-d dig path

  Specifies a path to a `dig` binary. Used for testing.

-D dsfromkey path

  Specifies a path to a `dnssec-dsfromkey` binary. Used for testing.
