The \fI\%\-A\fP option includes ZSKs (flags = 256). Revoked keys are never included. .sp The input keys can be specified in a number of ways: .sp By default, \fBdnssec\-dsfromkey\fP reads a key file named in the format \fBKnnnn.+aaa+iiiii.key\fP, as generated by \X'tty: link #std-iscman-dnssec-keygen'\fI\%dnssec\-keygen\fP\X'tty: link'\&. .sp With the \fI\%\-f file\fP option, \fBdnssec\-dsfromkey\fP reads keys from a zone file or partial zone file (which can contain just the DNSKEY records). .sp With the \fI\%\-s\fP option, \fBdnssec\-dsfromkey\fP reads a \fBkeyset\-\fP file, as generated by \X'tty: link #std-iscman-dnssec-keygen'\fI\%dnssec\-keygen\fP\X'tty: link' \fI\%\-C\fP\&. .SH OPTIONS .INDENT 0.0 .TP .B \-1 This option is an abbreviation for \fI\%\-a SHA1\fP\&. .UNINDENT .INDENT 0.0 .TP .B \-2 This option is an abbreviation for \fI\%\-a SHA\-256\fP\&. .UNINDENT .INDENT 0.0 .TP .B \-a algorithm This option specifies a digest algorithm to use when converting DNSKEY records to DS records. This option can be repeated, so that multiple DS records are created for each DNSKEY record. .sp 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. .UNINDENT .INDENT 0.0 .TP .B \-A This option indicates that ZSKs are to be included when generating DS records. Without this option, only keys which have the KSK flag set are converted to DS records and printed. This option is only useful in \fI\%\-f\fP zone file mode. .UNINDENT .INDENT 0.0 .TP .B \-c class This option specifies the DNS class; the default is IN. This option is only useful in \fI\%\-s\fP keyset or \fI\%\-f\fP zone file mode. .UNINDENT .INDENT 0.0 .TP .B \-C This option generates CDS records rather than DS records. .UNINDENT .INDENT 0.0 .TP .B \-f file This option sets zone file mode, in which the final dnsname argument of \fBdnssec\-dsfromkey\fP is the DNS domain name of a zone whose master file can be read from \fBfile\fP\&. If the zone name is the same as \fBfile\fP, then it may be omitted. .sp If \fBfile\fP is \fB\-\fP, then the zone data is read from the standard input. This makes it possible to use the output of the \X'tty: link #std-iscman-dig'\fI\%dig\fP\X'tty: link' command as input, as in: .sp \fBdig dnskey example.com | dnssec\-dsfromkey \-f \- example.com\fP .UNINDENT .INDENT 0.0 .TP .B \-h This option prints usage information. .UNINDENT .INDENT 0.0 .TP .B \-K directory This option tells BIND 9 to look for key files or \fBkeyset\-\fP files in \fBdirectory\fP\&. .UNINDENT .INDENT 0.0 .TP .B \-s This option enables keyset mode, in which the final dnsname argument from \fBdnssec\-dsfromkey\fP is the DNS domain name used to locate a \fBkeyset\-\fP file. .UNINDENT .INDENT 0.0 .TP .B \-T TTL This option specifies the TTL of the DS records. By default the TTL is omitted. .UNINDENT .INDENT 0.0 .TP .B \-v level This option sets the debugging level. .UNINDENT .INDENT 0.0 .TP .B \-V This option prints version information. .UNINDENT .SH EXAMPLE .sp To build the SHA\-256 DS RR from the \fBKexample.com.+003+26160\fP keyfile, issue the following command: .sp \fBdnssec\-dsfromkey \-2 Kexample.com.+003+26160\fP .sp The command returns something similar to: .sp \fBexample.com.
