the problems related to the handling of broken DNSSEC trust chains. This fix is only relevant for those who have DNSSEC validation enabled and configure trust anchors from third parties, either manually, or through a system like DLV.

<para><command>dnssec-keyfromlabel</command>
|

gets keys with the given label from a crypto hardware and builds

|
key files for DNSSEC (Secure DNS), as defined in RFC 2535
|
|
and RFC 4034.

<listitem>
|
|
<para>
|
|
Selects the cryptographic algorithm. The value of
|
|
<option>algorithm</option> must be one of RSAMD5,
|
|
RSASHA1, DSA, NSEC3RSASHA1, NSEC3DSA, RSASHA256,
|
|
RSASHA512 or DH (Diffie Hellman).
|
|
These values are case insensitive.
|
|
</para>
|
|
<para>
|
|
If no algorithm is specified, then RSASHA1 will be used by
|
|
default, unless the <option>-3</option> option is specified,
|
|
in which case NSEC3RSASHA1 will be used instead. (If
|
|
<option>-3</option> is used and an algorithm is specified,
|
|
that algorithm will be checked for compatibility with NSEC3.)
|
|
</para>
|
|
<para>
|
|
Note 1: that for DNSSEC, RSASHA1 is a mandatory to implement
|
|
algorithm, and DSA is recommended.
|
|
</para>
|
|
<para>
|
|
Note 2: DH automatically sets the -k flag.

<para>

Specifies the owner type of the key. The value of

<option>nametype</option> must either be ZONE (for a DNSSEC
|
|
zone key (KEY/DNSKEY)), HOST or ENTITY (for a key associated with
|
|
a host (KEY)),
|
|
USER (for a key associated with a user(KEY)) or OTHER (DNSKEY).
|

These values are

case insensitive.

Sets the protocol value for the generated key. The protocol

is a number between 0 and 255. The default is 3 (DNSSEC).

RFC 2535 and its successors.

one of AUTHCONF, NOAUTHCONF, NOAUTH, or NOCONF. The default

is AUTHCONF. AUTH refers to the ability to authenticate

data, and CONF the ability to encrypt data.

<title>GENERATED KEY FILES</title>
|
|
<para>
|
|
When <command>dnssec-keyfromlabel</command> completes
|
|
successfully,
|
|
it prints a string of the form <filename>Knnnn.+aaa+iiiii</filename>
|
|
to the standard output. This is an identification string for
|
|
the key files it has generated.

</para>

<para><command>dnssec-keyfromlabel</command>

creates two files, with names based

on the printed string. <filename>Knnnn.+aaa+iiiii.key</filename>

contains the public key, and

<filename>Knnnn.+aaa+iiiii.private</filename> contains the

|
private
|

key.

</para>
|
|
<para>
|

The <filename>.key</filename> file contains a DNS KEY record

that

can be inserted into a zone file (directly or with a $INCLUDE

|
statement).
|
|
</para>

<para>

The <filename>.private</filename> file contains algorithm

specific

fields. For obvious security reasons, this file does not have

|
general read permission.
