970N/A gets keys with the given label from a crypto hardware and builds
970N/A key files for DNSSEC (Secure DNS), as defined in RFC 2535
970N/A The <

970N/A Selects the cryptographic algorithm. The value of
1029N/A <
code class="option">algorithm</
code> must be one of RSAMD5 (RSA),
1029N/A RSASHA1, DSA, NSEC3RSASHA1, NSEC3DSA or DH (Diffie Hellman).
1124N/A These values are case insensitive.
1124N/A If no algorithm is specified, then RSASHA1 will be used by
1124N/A default, unless the <
code class="option">-3</
code> option is specified,
1124N/A in which case NSEC3RSASHA1 will be used instead.
98N/A Note 1: that for DNSSEC, RSASHA1 is a mandatory to implement
1124N/A algorithm, and DSA is recommended.
1124N/A Note 2: DH automatically sets the -k flag.

98N/A separated by a colon, as in "pkcs11:keylabel".

1176N/A will include the key's creation date in the metadata stored
493N/A with the private key, and other dates may be set there as well
965N/A (publication date, activation date, etc). Keys that include
965N/A this data may be incompatible with older versions of BIND; the

910N/A Sets the protocol value for the key. The protocol
98N/A is a number between 0 and 255. The default is 3 (DNSSEC).

1193N/A Dates can be expressed in the format YYYYMMDD or YYYYMMDDHHMMSS.
1193N/A If the argument begins with a '+' or '-', it is interpreted as
1193N/A an offset from the present time. For convenience, if such an offset
1193N/A is followed by one of the suffixes 'y', 'mo', 'w', 'd', 'h', or 'mi',
1193N/A then the offset is computed in years (defined as 365 24-hour days,
1193N/A ignoring leap years), months (defined as 30 24-hour days), weeks,
1193N/A days, hours, or minutes, respectively. Without a suffix, the offset
606N/A is computed in seconds.
