NAME
ntp-keygen - Create a NTP host key
SYNOPSIS
ntp-keygen [-flag [value]]... [--opt-name [[=| ]value]]...
All arguments must be options.
DESCRIPTION
This manual page briefly documents the ntp-keygen command. If there is
no new host key, look for an existing one. If one is not found, create
it.
OPTIONS
-c scheme, --certificate=scheme
certificate scheme.
scheme is one of RSA-MD2, RSA-MD5, RSA-SHA, RSA-SHA1, RSA-MDC2,
RSA-RIPEMD160, DSA-SHA, or DSA-SHA1.
Select the certificate message digest/signature encryption
scheme. Note that RSA schemes must be used with a RSA sign key
and DSA schemes must be used with a DSA sign key. The default
without this option is RSA-MD5.
-d, --debug-level
Increase output debug message level. This option may appear an
unlimited number of times.
Increase the debugging message output level.
-D string, --set-debug-level=string
Set the output debug message level. This option may appear an
unlimited number of times.
Set the output debugging level. Can be supplied multiple times,
but each overrides the previous value(s).
-e, --id-key
Write IFF or GQ identity keys.
Write the IFF or GQ client keys to the standard output. This is
intended for automatic key distribution by mail.
-G, --gq-params
Generate GQ parameters and keys.
Generate parameters and keys for the GQ identification scheme,
obsoleting any that may exist.
-H, --host-key
generate RSA host key.
Generate new host keys, obsoleting any that may exist.
-I, --iffkey
generate IFF parameters.
Generate parameters for the IFF identification scheme, obsolet-
ing any that may exist.
-i issuer-name, --issuer-name=issuer-name
set issuer name.
Set the suject name to name. This is used as the subject field
in certificates and in the file name for host and sign keys.
-M, --md5key
generate MD5 keys.
Generate MD5 keys, obsoleting any that may exist.
-m modulus, --modulus=modulus
modulus. This option takes an integer number as its argument.
The value of modulus is constrained to being:
in the range 256 through 2048
The number of bits in the prime modulus. The default is 512.
-P, --pvt-cert
generate PC private certificate.
Generate a private certificate. By default, the program gener-
ates public certificates.
-p passwd, --pvt-passwd=passwd
output private password.
Encrypt generated files containing private data with the speci-
fied password and the DES-CBC algorithm.
-q passwd, --get-pvt-passwd=passwd
input private password.
Set the password for reading files to the specified password.
-S sign, --sign-key=sign
generate sign key (RSA or DSA).
Generate a new sign key of the designated type, obsoleting any
that may exist. By default, the program uses the host key as
the sign key.
-s host, --subject-name=host
set subject name.
Set the issuer name to name. This is used for the issuer field
in certificates and in the file name for identity files.
-T, --trusted-cert
trusted certificate (TC scheme).
Generate a trusted certificate. By default, the program gener-
ates a non-trusted certificate.
-V num, --mv-params=num
generate <num> MV parameters. This option takes an integer num-
ber as its argument.
Generate parameters and keys for the Mu-Varadharajan (MV) iden-
tification scheme.
-v num, --mv-keys=num
update <num> MV keys. This option takes an integer number as
its argument.
This option has not been fully documented.
-?, --help
Display extended usage information and exit.
-!, --more-help
Extended usage information passed thru pager.
-> [rcfile], --save-opts[=rcfile]
Save the option state to rcfile. The default is the last con-
figuration file listed in the OPTION PRESETS section, below.
-< rcfile, --load-opts=rcfile, --no-load-opts
Load options from rcfile. The no-load-opts form will disable
the loading of earlier RC/INI files. --no-load-opts is handled
early, out of order.
- [{v|c|n}], --version[={v|c|n}]
Output version of program and exit. The default mode is `v', a
simple version. The `c' mode will print copyright information
and `n' will print the full copyright notice.
OPTION PRESETS
Any option that is not marked as not presettable may be preset by load-
ing values from configuration ("RC" or ".INI") file(s) and values from
environment variables named:
NTP_KEYGEN_<option-name> or NTP_KEYGEN
The environmental presets take precedence (are processed later than)
the configuration files. The homerc files are "$HOME", and ".". If
any of these are directories, then the file .ntprc is searched for
within those directories.
