NAME

netkey-tool - administrative utility for Netkey E4 cards

SYNOPSIS

netkey-tool [OPTIONS] [COMMAND]

DESCRIPTION

The netkey-tool utility can be used from the command line to perform some smart card
operations with NetKey E4 cards that cannot be done easily with other OpenSC-tools, such
as changing local PINs, storing certificates into empty NetKey E4 cert-files or displaying
the initial PUK-value.

OPTIONS

--help, -h
Displays a short help message.

--pin pin-value, -p pin-value
Specifies the current value of the global PIN.

--puk pin-value, -u pin-value
Specifies the current value of the global PUK.

--pin0 pin-value, -0 pin-value
Specifies the current value of the local PIN0 (aka local PIN).

--pin1 pin-value, -1 pin-value
Specifies the current value of the local PIN1 (aka local PUK).

--reader number, -r number
Use smart card in specified reader. Default is reader 0.

-v
Causes netkey-tool to be more verbose. This options may be specified multiple times to
increase verbosity.

PIN FORMAT

With the -p, -u, -0 or the -1 one of the cards pins may be specified. You may use plain
ascii-strings (i.e. 123456) or a hex-string (i.e. 31:32:33:34:35:36). A hex-string must
consists of exacly n 2-digit hexnumbers separated by n-1 colons. Otherwise it will be
interpreted as an ascii string. For example :12:34: and 1:2:3:4 are both pins of length 7,
while 12:34 and 01:02:03:04 are pins of length 2 and 4.

COMMANDS

When used without any options or commands, netkey-tool will display information about the
smart cards pins and certificates. This will not change your card in any aspect (assumed
there are no bugs in netkey-tool). In particular the tries-left counters of the pins are
investigated without doing actual pin-verifications.

If you specify the global PIN via the --pin option, netkey-tool will also display the
initial value of the cards global PUK. If your global PUK was changed netkey-tool will
still display its initial value. There's no way to recover a lost global PUK once it was
changed. There's also no way to display the initial value of your global PUK without
knowing the current value of your global PIN.

For most of the commands that netkey-tool can execute, you have to specify one pin. One
notable exeption is the nullpin command, but this command can only be executed once in the
lifetime of a NetKey E4 card.

cert number filename
This command will read one of your cards certificates (as specified by number) and
save this certificate into file filename in PEM-format. Certificates on a NetKey E4
card are readable without a pin, so you don't have to specify one.

cert filename number
This command will read the first PEM-encoded certificate from file filename and store
this into your smart cards certificate file number. Some of your smart cards
certificate files might be readonly, so this will not work with all values of number.
If a certificate file is writable you must specify a pin in order to change it. If you
try to use this command without specifying a pin, netkey-tool will tell you which one
is needed.

change { pin | puk | pin0 | pin1 } new-pin
This changes the value of the specified pin to the given new value. You must specify
either the current value of the pin or another pin to be able to do this and if you
don't specify a correct one, netkey-tool will tell you which one is needed.

nullpin initial-pin
This command can be executed only if the global PIN of your card is in nullpin-state.
There's no way to return back to nullpin-state once you have changed your global PIN.
You don't need a pin to execute the nullpin-command. After a succesfull
nullpin-command netkey-tool will display your cards initial PUK-value.

unblock { pin | pin0 | pin1 }
This unblocks the specified pin. You must specify another pin to be able to do this
and if you don't specify a correct one, netkey-tool will tell you which one is needed.
