 38.SH "DESCRIPTION"
 39.PP
 40\fBdnssec\-dsfromkey\fR
 41outputs the Delegation Signer (DS) resource record (RR), as defined in RFC 3658 and RFC 4509, for the given key(s).
 42.SH "OPTIONS"
 43.PP
 44\-1
 45.RS 4
 46Use SHA\-1 as the digest algorithm (the default is to use both SHA\-1 and SHA\-256).
 47.RE
 48.PP
 49\-2
 50.RS 4
 51Use SHA\-256 as the digest algorithm.
 52.RE
 53.PP
 54\-a \fIalgorithm\fR
 55.RS 4
 56Select the digest algorithm. The value of
 57\fBalgorithm\fR
 58must be one of SHA\-1 (SHA1), SHA\-256 (SHA256) or GOST. These values are case insensitive.
 59.RE
 60.PP
 61\-K \fIdirectory\fR
 62.RS 4
 63Look for key files (or, in keyset mode,
 64\fIkeyset\-\fR
 65files) in
 66\fBdirectory\fR.
 67.RE
 68.PP
 69\-f \fIfile\fR
 70.RS 4
 71Zone file mode: in place of the keyfile name, the argument is the DNS domain name of a zone master file, which can be read from
 72\fBfile\fR. If the zone name is the same as
 73\fBfile\fR, then it may be omitted.
 74.RE
 75.PP
 76\-A
 77.RS 4
 78Include ZSK's when generating DS records. Without this option, only keys which have the KSK flag set will be converted to DS records and printed. Useful only in zone file mode.
 79.RE
 80.PP
 81\-l \fIdomain\fR
 82.RS 4
 83Generate a DLV set instead of a DS set. The specified
 84\fBdomain\fR
 85is appended to the name for each record in the set. The DNSSEC Lookaside Validation (DLV) RR is described in RFC 4431.
 86.RE
 87.PP
 88\-s
 89.RS 4
 90Keyset mode: in place of the keyfile name, the argument is the DNS domain name of a keyset file.
 91.RE
 92.PP
 93\-c \fIclass\fR
 94.RS 4
 95Specifies the DNS class (default is IN). Useful only in keyset or zone file mode.
 96.RE
 97.PP
 98\-v \fIlevel\fR
 99.RS 4
100Sets the debugging level.
101.RE
102.SH "EXAMPLE"
103.PP
104To build the SHA\-256 DS RR from the
105\fBKexample.com.+003+26160\fR
106keyfile name, the following command would be issued:
107.PP
108\fBdnssec\-dsfromkey \-2 Kexample.com.+003+26160\fR
109.PP
110The command would print something like:
111.PP
112\fBexample.com. IN DS 26160 5 2 3A1EADA7A74B8D0BA86726B0C227AA85AB8BBD2B2004F41A868A54F0 C5EA0B94\fR
113.SH "FILES"
114.PP
115The keyfile can be designed by the key identification
116\fIKnnnn.+aaa+iiiii\fR
117or the full file name
118\fIKnnnn.+aaa+iiiii.key\fR
119as generated by
120dnssec\-keygen(8).
121.PP
122The keyset file name is built from the
123\fBdirectory\fR, the string
124\fIkeyset\-\fR
125and the
126\fBdnsname\fR.
127.SH "CAVEAT"
128.PP
129A keyfile error can give a "file not found" even if the file exists.
130.SH "SEE ALSO"
131.PP
