6 dnssec-settime - set the key timing metadata for a DNSSEC key

9 dnssec-settime [-f] [-K directory] [-L ttl] [-P date/offset]
10 [-P sync date/offset] [-A date/offset] [-R date/offset]
11 [-I date/offset] [-D date/offset] [-D sync date/offset]
12 [-S key] [-i interval] [-h] [-V] [-v level] [-E engine]
13 {keyfile}
14
16 dnssec-settime reads a DNSSEC private key file and sets the key timing
17 metadata as specified by the -P, -A, -R, -I, and -D options. The
18 metadata can then be used by dnssec-signzone or other signing software
19 to determine when a key is to be published, whether it should be used
20 for signing a zone, etc.
21 If none of these options is set on the command line, then
23 dnssec-settime simply prints the key timing metadata already stored in
24 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
29 description of the metadata is also placed in comments in the key file.
30 The private file's permissions are always set to be inaccessible to
31 anyone other than the owner (mode 0600).
32
34 -f
35 Force an update of an old-format key with no metadata fields.
36 Without this option, dnssec-settime will fail when attempting to
37 update a legacy key. With this option, the key will be recreated in
38 the new format, but with the original key data retained. The key's
39 creation date will be set to the present time. If no other values
40 are specified, then the key's publication and activation dates will
41 also be set to the present time.
42 -K directory
44 Sets the directory in which the key files are to reside.
45 -L ttl
47 Sets the default TTL to use for this key when it is converted into
48 a DNSKEY RR. If the key is imported into a zone, this is the TTL
49 that will be used for it, unless there was already a DNSKEY RRset
50 in place, in which case the existing TTL would take precedence. If
51 this value is not set and there is no existing DNSKEY RRset, the
52 TTL will default to the SOA TTL. Setting the default TTL to 0 or
53 none removes it from the key.
54 -h
56 Emit usage message and exit.
57 -V
59 Prints version information.
60 -v level
62 Sets the debugging level.
63 -E engine
65 Specifies the cryptographic hardware to use, when applicable.
66 When BIND is built with OpenSSL PKCS#11 support, this defaults to
68 the string "pkcs11", which identifies an OpenSSL engine that can
69 drive a cryptographic accelerator or hardware service module. When
70 BIND is built with native PKCS#11 cryptography
71 (--enable-native-pkcs11), it defaults to the path of the PKCS#11
72 provider library specified via "--with-pkcs11".
73
75 Dates can be expressed in the format YYYYMMDD or YYYYMMDDHHMMSS. If the
76 argument begins with a '+' or '-', it is interpreted as an offset from
77 the present time. For convenience, if such an offset is followed by one
78 of the suffixes 'y', 'mo', 'w', 'd', 'h', or 'mi', then the offset is
79 computed in years (defined as 365 24-hour days, ignoring leap years),
80 months (defined as 30 24-hour days), weeks, days, hours, or minutes,
81 respectively. Without a suffix, the offset is computed in seconds. To
82 unset a date, use 'none' or 'never'.
83 -P date/offset
85 Sets the date on which a key is to be published to the zone. After
86 that date, the key will be included in the zone but will not be
87 used to sign it.
88 -P sync date/offset
90 Sets the date on which CDS and CDNSKEY records that match this key
91 are to be published to the zone.
92 -A date/offset
94 Sets the date on which the key is to be activated. After that date,
95 the key will be included in the zone and used to sign it.
96 -R date/offset
98 Sets the date on which the key is to be revoked. After that date,
99 the key will be flagged as revoked. It will be included in the zone
100 and will be used to sign it.
101 -I date/offset
103 Sets the date on which the key is to be retired. After that date,
104 the key will still be included in the zone, but it will not be used
105 to sign it.
106 -D date/offset
108 Sets the date on which the key is to be deleted. After that date,
109 the key will no longer be included in the zone. (It may remain in
110 the key repository, however.)
111 -D sync date/offset
113 Sets the date on which the CDS and CDNSKEY records that match this
114 key are to be deleted.
115 -S predecessor key
117 Select a key for which the key being modified will be an explicit
118 successor. The name, algorithm, size, and type of the predecessor
119 key must exactly match those of the key being modified. The
120 activation date of the successor key will be set to the
121 inactivation date of the predecessor. The publication date will be
122 set to the activation date minus the prepublication interval, which
123 defaults to 30 days.
124 -i interval
126 Sets the prepublication interval for a key. If set, then the
127 publication and activation dates must be separated by at least this
128 much time. If the activation date is specified but the publication
129 date isn't, then the publication date will default to this much
130 time before the activation date; conversely, if the publication
131 date is specified but activation date isn't, then activation will
132 be set to this much time after publication.
133 If the key is being set to be an explicit successor to another key,
135 then the default prepublication interval is 30 days; otherwise it
136 is zero.
137 As with date offsets, if the argument is followed by one of the
139 suffixes 'y', 'mo', 'w', 'd', 'h', or 'mi', then the interval is
140 measured in years, months, weeks, days, hours, or minutes,
141 respectively. Without a suffix, the interval is measured in
142 seconds.
143
145 dnssec-settime can also be used to print the timing metadata associated
146 with a key.
147 -u
149 Print times in UNIX epoch format.
150 -p C/P/Psync/A/R/I/D/Dsync/all
152 Print a specific metadata value or set of metadata values. The -p
153 option may be followed by one or more of the following letters or
154 strings to indicate which value or values to print: C for the
155 creation date, P for the publication date, Psync for the CDS and
156 CDNSKEY publication date, A for the activation date, R for the
157 revocation date, I for the inactivation date, D for the deletion
158 date, and Dsync for the CDS and CDNSKEY deletion date To print all
159 of the metadata, use -p all.
