netkey-tool1OpenSCOpenSC Toolsopenscnetkey-tooladministrative utility for Netkey E4 cardsnetkey-toolOPTIONSCOMMANDDescriptionThe 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

num
Specify the reader to use. By default, the first
reader with a present card is used. If
num is an ATR, the
reader with a matching card will be chosen.
Causes netkey-tool to be more verbose. This
options may be specified multiple times to increase verbosity.PIN formatWith the , , or the
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 consist of exactly 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.CommandsWhen 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 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 exception is the nullpin command, but
this command can only be executed once in the lifetime of a NetKey E4 card.certnumberfilenameThis 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.certfilenamenumberThis 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.changepinpukpin0pin1new-pinThis 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.nullpininitial-pinThis 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 successful
nullpin-command netkey-tool will display your cards initial
PUK-value.unblockpinpin0pin1This 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.See alsoopensc-explorer1Authorsnetkey-tool was written by
