gets keys with the given label from a crypto hardware and builds
key files for DNSSEC (Secure DNS), as defined in RFC 2535

dt>
Selects the cryptographic algorithm. The value of
<
code class="option">algorithm</
code> must be one of RSAMD5 (RSA)
or RSASHA1, DSA, NSEC3RSASHA1, NSEC3DSA or DH (Diffie Hellman).
These values are case insensitive.
Note 1: that for DNSSEC, RSASHA1 is a mandatory to implement
algorithm, and DSA is recommended.
Note 2: DH automatically sets the -k flag.

Specifies the owner type of the key. The value of
<
code class="option">nametype</
code> must either be ZONE (for a DNSSEC
zone key (
KEY/
DNSKEY)), HOST or ENTITY (for a key associated with
USER (for a key associated with a user(KEY)) or OTHER (DNSKEY).
<

Indicates that the DNS record containing the key should have
the specified class. If not specified, class IN is used.
<

Set the specified flag in the flag field of the
KEY/
DNSKEY record.
The only recognized flag is KSK (Key Signing Key) DNSKEY.

Sets the protocol value for the generated key. The protocol
is a number between 0 and 255. The default is 3 (DNSSEC).
Other possible values for this argument are listed in
RFC 2535 and its successors.
<
dt><

dt>
Indicates the use of the key. <
code class="option">type</
code> must be
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.
