66 <title>DESCRIPTION</title>
67 <para><command>dnssec-settime</command>
68 reads a DNSSEC private key file and sets the key timing metadata
69 as specified by the <option>-P</option>, <option>-A</option>,
70 <option>-R</option>, <option>-I</option>, and <option>-D</option>
71 options. The metadata can then be used by
72 <command>dnssec-signzone</command> or other signing software to
73 determine when a key is to be published, whether it should be
74 used for signing a zone, etc.
77 If none of these options is set on the command line,
78 then <command>dnssec-settime</command> simply prints the key timing
79 metadata already stored in the key.
82 When key metadata fields are changed, both files of a key
83 pair (<filename>Knnnn.+aaa+iiiii.key</filename> and
84 <filename>Knnnn.+aaa+iiiii.private</filename>) are regenerated.
85 Metadata fields are stored in the private file. A human-readable
86 description of the metadata is also placed in comments in the key
87 file. The private file's permissions are always set to be
88 inaccessible to anyone other than the owner (mode 0600).
93 <title>OPTIONS</title>
100 Force an update of an old-format key with no metadata fields.
101 Without this option, <command>dnssec-settime</command> will
102 fail when attempting to update a legacy key. With this option,
103 the key will be recreated in the new format, but with the
104 original key data retained. The key's creation date will be
105 set to the present time. If no other values are specified,
106 then the key's publication and activation dates will also
107 be set to the present time.
113 <term>-K <replaceable class="parameter">directory</replaceable></term>
116 Sets the directory in which the key files are to reside.
122 <term>-L <replaceable class="parameter">ttl</replaceable></term>
125 Sets the default TTL to use for this key when it is converted
126 into a DNSKEY RR. If the key is imported into a zone,
127 this is the TTL that will be used for it, unless there was
128 already a DNSKEY RRset in place, in which case the existing TTL
129 would take precedence. Setting the default TTL to
130 <literal>0</literal> or <literal>none</literal> removes it.
139 Emit usage message and exit.
148 Prints version information.
154 <term>-v <replaceable class="parameter">level</replaceable></term>
157 Sets the debugging level.
163 <term>-E <replaceable class="parameter">engine</replaceable></term>
166 Use the given OpenSSL engine. When compiled with PKCS#11 support
167 it defaults to pkcs11; the empty name resets it to no engine.
175 <title>TIMING OPTIONS</title>
177 Dates can be expressed in the format YYYYMMDD or YYYYMMDDHHMMSS.
178 If the argument begins with a '+' or '-', it is interpreted as
179 an offset from the present time. For convenience, if such an offset
180 is followed by one of the suffixes 'y', 'mo', 'w', 'd', 'h', or 'mi',
181 then the offset is computed in years (defined as 365 24-hour days,
182 ignoring leap years), months (defined as 30 24-hour days), weeks,
183 days, hours, or minutes, respectively. Without a suffix, the offset
184 is computed in seconds. To unset a date, use 'none' or 'never'.
189 <term>-P <replaceable class="parameter">date/offset</replaceable></term>
192 Sets the date on which a key is to be published to the zone.
193 After that date, the key will be included in the zone but will
194 not be used to sign it.
200 <term>-A <replaceable class="parameter">date/offset</replaceable></term>
203 Sets the date on which the key is to be activated. After that
204 date, the key will be included in the zone and used to sign
211 <term>-R <replaceable class="parameter">date/offset</replaceable></term>
214 Sets the date on which the key is to be revoked. After that
215 date, the key will be flagged as revoked. It will be included
216 in the zone and will be used to sign it.
222 <term>-I <replaceable class="parameter">date/offset</replaceable></term>
225 Sets the date on which the key is to be retired. After that
226 date, the key will still be included in the zone, but it
227 will not be used to sign it.
233 <term>-D <replaceable class="parameter">date/offset</replaceable></term>
236 Sets the date on which the key is to be deleted. After that
237 date, the key will no longer be included in the zone. (It
238 may remain in the key repository, however.)
244 <term>-S <replaceable class="parameter">predecessor key</replaceable></term>
247 Select a key for which the key being modified will be an
248 explicit successor. The name, algorithm, size, and type of the
249 predecessor key must exactly match those of the key being
250 modified. The activation date of the successor key will be set
251 to the inactivation date of the predecessor. The publication
252 date will be set to the activation date minus the prepublication
253 interval, which defaults to 30 days.
259 <term>-i <replaceable class="parameter">interval</replaceable></term>
262 Sets the prepublication interval for a key. If set, then
263 the publication and activation dates must be separated by at least
264 this much time. If the activation date is specified but the
265 publication date isn't, then the publication date will default
266 to this much time before the activation date; conversely, if
267 the publication date is specified but activation date isn't,
268 then activation will be set to this much time after publication.
271 If the key is being set to be an explicit successor to another
272 key, then the default prepublication interval is 30 days;
273 otherwise it is zero.
276 As with date offsets, if the argument is followed by one of
277 the suffixes 'y', 'mo', 'w', 'd', 'h', or 'mi', then the
278 interval is measured in years, months, weeks, days, hours,
279 or minutes, respectively. Without a suffix, the interval is
288 <title>PRINTING OPTIONS</title>
290 <command>dnssec-settime</command> can also be used to print the
291 timing metadata associated with a key.
299 Print times in UNIX epoch format.
305 <term>-p <replaceable class="parameter">C/P/A/R/I/D/all</replaceable></term>
308 Print a specific metadata value or set of metadata values.
309 The <option>-p</option> option may be followed by one or more
310 of the following letters to indicate which value or values to print:
311 <option>C</option> for the creation date,
312 <option>P</option> for the publication date,
313 <option>A</option> for the activation date,
314 <option>R</option> for the revocation date,
315 <option>I</option> for the inactivation date, or
316 <option>D</option> for the deletion date.
317 To print all of the metadata, use <option>-p all</option>.
