6 YAKEYROLLD is an utility for genrating a sequence of KSK and ZSK for a
7 zone.

10 yakeyrolld command [argument]
11
13 The yakeyrolld program generates a sequence of KSK and ZSK for a zone,
14 with all the steps of their lifecycles.
15 yakeyrolld is part of the YADIFA distribution from EURid vzw/asbl. The
17 latest version of YADIFA can be found on:

22 A lifecyle for a key has several steps:
23 * Time of creation
25 * Time of publication
27 * Time of activation
29 * Time of de-activation
31 * Time of un-publication.
33 These times are determined using a cron-like schedule.
35 For all these steps, it computes the following:
37 * The expected DNSSEC and RRSIG DNSSEC records on the primary be‐
39 fore the step is started
40 * The ZSK files to add
42 * The ZSK files to remove
44 * The DNSSEC and RRSIG DNSKEY records to add
46 * The DNSKEY and RRSIG DNSKEY records to remove
48 * The expected DNSKEY and RRSIG DNSKEY records on the dns primary
50 after the step has been completed.
51 Each step is stored as a file. The file contains fields like:
53 epochus An integer with the epoch of the step expressed in microsec‐
55 onds.
56 dateus A user-friendly date text matching the epochus field.
58 actions A list of actions expected to happen on the step (informa‐
60 tional).
61 debug A text meant to help understand the step (informational).
63 update Each entry is a dynamic update command to be sent to the
65 server.
66 expect Each entry defines one record expected to be in the zone on the
68 server prior to executing the current step.
69 endresult Each entry defines one record expected to be in the zone on
71 the server after the step has been executed.
72 add Defines a key file to create in keys-path.
74 del Names a key file to delete from keys-path.

78 --help|-h Shows the help
79 --version|-V Prints the version of the software
81 --config|-c configfile Sets the configuration file to use
83 --mode|-m generate | play | playloop | print | print-json Sets the
85 program mode
86 --domain fqdn The domain name
88 --path|-p directory The directory where to store the keys
90 --server|-s address The address of the server
92 --ttl|-t seconds The ttl to use for both dnskey and rrsig records
94 --explain prints the planned schedule
96 --reset start by removing all the keys and create a new KSK and a new
98 ZSK. The server will not be queried.
99 --policy Name of the policy to use
101 --from time The lower time bound covered by the plan (now)
103 --until time The upper time bound covered by the plan (+1y)
105 --dryrun Do not write files to disk, do not send updates to the server
107 --wait Wait for yadifad to answer before starting to work (default)
109 --nowait Do not wait for yadifad to answer before starting to work
111 --daemon Daemonise the program for supported modes (default)
113 --nodaemon Do not daemonise the program
115 --noconfirm Do not ask for confirmation before doing a data reset
117
119 The yakeyrolld daemon writes key files in the yadifad keys directory
120 and pushes DNSKEY and RRSIG records with a dynamic update.
121 Zones managed by the keyroll needs to have the rrsig-nsupdate-allowed
122 setting enabled (<zone> section).
123 In generation mode, the daemon needs access to both the plan and pri‐
124 vate keys directory.
125 For all other modes, the private keys directory is ignored.
126 When not doing any kind of generation, they should not be kept on the
127 machine. Their encrypted backup sitting in a safe place.
128 Initialisation
130 Destroys all current data that could exist and starts from noth‐
131 ing. Creates all the steps of the rolls for the next two years.
132 Creates all the private keys in a separate directory.
133 The directory that contains the private key files is required
134 for this command as private keys will be added.
135 yakeyrolld -m generate --until +1y --reset
137 Renewal
139 In order to extend a plan further, simply do another generation.
140 The operation loads the current plan, extends it to cover the
141 new limit date and saves the updated modified version back on
142 disk.
143 Previously stored private keys may be used to generate signa‐
144 tures and new private keys may be added.
145 Because of this, the directory that contains the private key
146 files is required for this command.
147 yakeyrolld -m generate --until +1y
149 Plan calendar
151 Details of the current plan can be printed on stdout using:
152 yakeyrolld -m print
154 The output format of that command isn't meant to be parsed by a
156 program.
157 For a script, use instead:
159 yakeyrolld -m print-json
161 Daemon
163 To start the rolling the keys and pushing them to the server,
164 use:
165 yakeyrolld -m playloop
167
169 ${SYSCONFDIR}/yakeyrolld.conf
170 The default yakeyrolld configuration file.
