Possible formats are ``text`` 51 (the default) and ``raw``. This option is primarily intended to be used 52 for dynamic signed zones, so that the dumped zone file in a non-text 53 format containing updates can be verified independently. 54 This option is not useful for non-dynamic zones. 55 56.. option:: -o origin 57 58 This option indicates the zone origin. If not specified, the name of the zone file is 59 assumed to be the origin. 60 61.. option:: -v level 62 63 This option sets the debugging level. 64 65.. option:: -V 66 67 This option prints version information. 68 69.. option:: -q 70 71 This option sets quiet mode, which suppresses output. Without this option, when :program:`dnssec-verify` 72 is run it prints to standard output the number of keys in use, the 73 algorithms used to verify the zone was signed correctly, and other status 74 information. With this option, all non-error output is suppressed, and only the exit 75 code indicates success. 76 77.. option:: -x 78 79 This option verifies only that the DNSKEY RRset is signed with key-signing keys. 80 Without this flag, it is assumed that the DNSKEY RRset is signed 81 by all active keys. When this flag is set, it is not an error if 82 the DNSKEY RRset is not signed by zone-signing keys. This corresponds 83 to the :option:`-x option in dnssec-signzone <dnssec-signzone -x>`. 84 85.. option:: -z 86 87 This option indicates that the KSK flag on the keys should be ignored when determining whether the zone is 88 correctly signed. Without this flag, it is assumed that there is 89 a non-revoked, self-signed DNSKEY with the KSK flag set for each 90 algorithm, and that RRsets other than DNSKEY RRset are signed with 91 a different DNSKEY without the KSK flag set. 92 93 With this flag set, BIND 9 only requires that for each algorithm, there 94 be at least one non-revoked, self-signed DNSKEY, regardless of 95 the KSK flag state, and that other RRsets be signed by a 96 non-revoked key for the same algorithm that includes the self-signed 97 key; the same key may be used for both purposes. This corresponds to 98 the :option:`-z option in dnssec-signzone <dnssec-signzone -z>`. 99 100.. option:: zonefile 101 102 This option indicates the file containing the zone to be signed. 103 104See Also 105~~~~~~~~ 106 107:iscman:`dnssec-signzone(8) <dnssec-signzone>`, BIND 9 Administrator Reference Manual, :rfc:`4033`. 108
