17 dnssec-settime reads a DNSSEC private key file and sets the key timing
18 metadata as specified by the -P, -A, -R, -I, and -D options. The meta‐
19 data can then be used by dnssec-signzone or other signing software to
20 determine when a key is to be published, whether it should be used for
21 signing a zone, etc.
22 If none of these options is set on the command line, dnssec-settime
24 simply prints the key timing metadata already stored in the key.
25 When key metadata fields are changed, both files of a key pair
27 (Knnnn.+aaa+iiiii.key and Knnnn.+aaa+iiiii.private) are regenerated.
28 Metadata fields are stored in the private file. A human-readable de‐
30 scription of the metadata is also placed in comments in the key file.
31 The private file's permissions are always set to be inaccessible to
32 anyone other than the owner (mode 0600).
33 When working with state files, it is possible to update the timing
35 metadata in those files as well with -s. With this option, it is also
36 possible to update key states with -d (DS), -k (DNSKEY), -r (RRSIG of
37 KSK), or -z (RRSIG of ZSK). Allowed states are HIDDEN, RUMOURED, OMNI‐
38 PRESENT, and UNRETENTIVE.
39 The goal state of the key can also be set with -g. This should be ei‐
41 ther HIDDEN or OMNIPRESENT, representing whether the key should be re‐
42 moved from the zone or published.
43 It is NOT RECOMMENDED to manipulate state files manually, except for
45 testing purposes.
46
48 -f This option forces an update of an old-format key with no meta‐
49 data fields. Without this option, dnssec-settime fails when at‐
50 tempting to update a legacy key. With this option, the key is
51 recreated in the new format, but with the original key data re‐
52 tained. The key's creation date is set to the present time. If
53 no other values are specified, then the key's publication and
54 activation dates are also set to the present time.
55 -K directory
57 This option sets the directory in which the key files are to re‐
58 side.
59 -L ttl This option sets the default TTL to use for this key when it is
61 converted into a DNSKEY RR. This is the TTL used when the key is
62 imported into a zone, unless there was already a DNSKEY RRset in
63 place, in which case the existing TTL takes precedence. If this
64 value is not set and there is no existing DNSKEY RRset, the TTL
65 defaults to the SOA TTL. Setting the default TTL to 0 or none
66 removes it from the key.
67 -h This option emits a usage message and exits.
69 -V This option prints version information.
71 -v level
73 This option sets the debugging level.
74 -E engine
76 This option specifies the cryptographic hardware to use, when
77 applicable.
78 When BIND 9 is built with OpenSSL, this needs to be set to the
80 OpenSSL engine identifier that drives the cryptographic acceler‐
81 ator or hardware service module (usually pkcs11).
82
84 Dates can be expressed in the format YYYYMMDD or YYYYMMDDHHMMSS (which
85 is the format used inside key files), or 'Day Mon DD HH:MM:SS YYYY' (as
86 printed by dnssec-settime -p), or UNIX epoch time (as printed by
87 dnssec-settime -up), or the literal now.
88 The argument can be followed by + or - and an offset from the given
90 time. The literal now can be omitted before an offset. The offset can
91 be followed by one of the suffixes y, mo, w, d, h, or mi, so that it is
92 computed in years (defined as 365 24-hour days, ignoring leap years),
93 months (defined as 30 24-hour days), weeks, days, hours, or minutes,
94 respectively. Without a suffix, the offset is computed in seconds.
95 To unset a date, use none, never, or unset.
97 All these formats are case-insensitive.
99 -P date/offset
101 This option sets the date on which a key is to be published to
102 the zone. After that date, the key is included in the zone but
103 is not used to sign it.
104 ds date/offset
106 This option sets the date on which DS records that match
107 this key have been seen in the parent zone.
108 sync date/offset
110 This option sets the date on which CDS and CDNSKEY
111 records that match this key are to be published to the
112 zone.
113 -A date/offset
115 This option sets the date on which the key is to be activated.
116 After that date, the key is included in the zone and used to
117 sign it.
118 -R date/offset
120 This option sets the date on which the key is to be revoked. Af‐
121 ter that date, the key is flagged as revoked. It is included in
122 the zone and is used to sign it.
123 -I date/offset
125 This option sets the date on which the key is to be retired. Af‐
126 ter that date, the key is still included in the zone, but it is
127 not used to sign it.
128 -D date/offset
130 This option sets the date on which the key is to be deleted. Af‐
131 ter that date, the key is no longer included in the zone. (How‐
132 ever, it may remain in the key repository.)
133 ds date/offset
135 This option sets the date on which the DS records that
136 match this key have been seen removed from the parent
137 zone.
138 sync date/offset
140 This option sets the date on which the CDS and CDNSKEY
141 records that match this key are to be deleted.
142 -S predecessor key
144 This option selects a key for which the key being modified is an
145 explicit successor. The name, algorithm, size, and type of the
146 predecessor key must exactly match those of the key being modi‐
147 fied. The activation date of the successor key is set to the in‐
148 activation date of the predecessor. The publication date is set
149 to the activation date minus the prepublication interval, which
150 defaults to 30 days.
151 -i interval
153 This option sets the prepublication interval for a key. If set,
154 then the publication and activation dates must be separated by
155 at least this much time. If the activation date is specified but
156 the publication date is not, the publication date defaults to
157 this much time before the activation date; conversely, if the
158 publication date is specified but not the activation date, acti‐
159 vation is set to this much time after publication.
160 If the key is being created as an explicit successor to another
162 key, then the default prepublication interval is 30 days; other‐
163 wise it is zero.
164 As with date offsets, if the argument is followed by one of the
166 suffixes y, mo, w, d, h, or mi, the interval is measured in
167 years, months, weeks, days, hours, or minutes, respectively.
168 Without a suffix, the interval is measured in seconds.
169
171 To test dnssec-policy it may be necessary to construct keys with arti‐
172 ficial state information; these options are used by the testing frame‐
173 work for that purpose, but should never be used in production.
174 Known key states are HIDDEN, RUMOURED, OMNIPRESENT, and UNRETENTIVE.
176 -s This option indicates that when setting key timing data, the
178 state file should also be updated.
179 -g state
181 This option sets the goal state for this key. Must be HIDDEN or
182 OMNIPRESENT.
183 -d state date/offset
185 This option sets the DS state for this key as of the specified
186 date, offset from the current date.
187 -k state date/offset
189 This option sets the DNSKEY state for this key as of the speci‐
190 fied date, offset from the current date.
191 -r state date/offset
193 This option sets the RRSIG (KSK) state for this key as of the
194 specified date, offset from the current date.
195 -z state date/offset
197 This option sets the RRSIG (ZSK) state for this key as of the
198 specified date, offset from the current date.
199
201 dnssec-settime can also be used to print the timing metadata associated
202 with a key.
203 -u This option indicates that times should be printed in Unix epoch
205 format.
206 -p C/P/Pds/Psync/A/R/I/D/Dds/Dsync/all
208 This option prints a specific metadata value or set of metadata
209 values. The -p option may be followed by one or more of the
210 following letters or strings to indicate which value or values
211 to print: C for the creation date, P for the publication date,
212 Pds` for the DS publication date, ``Psync for the CDS and
213 CDNSKEY publication date, A for the activation date, R for the
214 revocation date, I for the inactivation date, D for the deletion
215 date, Dds for the DS deletion date, and Dsync for the CDS and
216 CDNSKEY deletion date. To print all of the metadata, use all.
