9 netkey-tool [OPTIONS] [COMMAND]
10
12 The netkey-tool utility can be used from the command line to perform
13 some smart card operations with NetKey E4 cards that cannot be done
14 easily with other OpenSC-tools, such as changing local PINs, storing
15 certificates into empty NetKey E4 cert-files or displaying the initial
16 PUK-value.
17
19 --help, -h
20 Displays a short help message.
21 --reader number, -r number
23 Use smart card in specified reader. Default is reader 0.
24 -v
26 Causes netkey-tool to be more verbose. This options may be specified
27 multiple times to increase verbosity.
28 --pin pin-value, -p pin-value
30 Specifies the current value of the global PIN.
31 --puk pin-value, -u pin-value
33 Specifies the current value of the global PUK.
34 --pin0 pin-value, -0 pin-value
36 Specifies the current value of the local PIN0 (aka local PIN).
37 --pin1 pin-value, -1 pin-value
39 Specifies the current value of the local PIN1 (aka local PUK).
40
42 With the -p, -u, -0 or the -1 one of the cards pins may be specified.
43 You may use plain ascii-strings (i.e. 123456) or a hex-string (i.e.
44 31:32:33:34:35:36). A hex-string must consists of exacly n 2-digit
45 hexnumbers separated by n-1 colons. Otherwise it will be interpreted as
46 an ascii string. For example :12:34: and 1:2:3:4 are both pins of
47 length 7, while 12:34 and 01:02:03:04 are pins of length 2 and 4.

50 When used without any options or commands, netkey-tool will display
51 information about the smart cards pins and certificates. This will not
52 change your card in any aspect (assumed there are no bugs in
53 netkey-tool). In particular the tries-left counters of the pins are
54 investigated without doing actual pin-verifications.
55 If you specify the global PIN via the --pin option, netkey-tool will
57 also display the initial value of the cards global PUK. If your global
58 PUK was changed netkey-tool will still diplay its initial value.
59 There's no way to recover a lost global PUK once it was changed.
60 There's also no way to display the initial value of your global PUK
61 without knowing the current value of your global PIN.
62 For most of the commands that netkey-tool can execute, you have to
64 specify one pin. One notable exeption is the nullpin command, but this
65 command can only be executed once in the lifetime of a NetKey E4 card.
66 unblock { pin | pin0 | pin1 }
68 This unblocks the specified pin. You must specify another pin to be
69 able to do this and if you don't specify a correct one, netkey-tool
70 will tell you which one is needed.
71 change { pin | puk | pin0 | pin1 } new-pin
73 This changes the value of the specified pin to the given new value.
74 You must specify either the current value of the pin or another pin
75 to be able to do this and if you don't specify a correct one,
76 netkey-tool will tell you which one is needed.
77 nullpin initial-pin
79 This command can be executed only if the global PIN of your card is
80 in nullpin-state. There's no way to return back to nullpin-state
81 once you have changed your global PIN. You don't need a pin to
82 execute the nullpin-command. After a succesfull nullpin-command
83 netkey-tool will display your cards initial PUK-value.
84 cert number filename
86 This command will read one of your cards certificates (as specified
87 by number) and save this certificate into file filename in
88 PEM-format. Certificates on a NetKey E4 card are readable without a
89 pin, so you don't have to specify one.
90 cert filename number
92 This command will read the first PEM-encoded certificate from file
93 filename and store this into your smart cards certificate file
94 number. Some of your smart cards certificate files might be
95 readonly, so this will not work with all values of number. If a
96 certificate file is writable you must specify a pin in order to
97 change it. If you try to use this command without specifying a pin,
98 netkey-tool will tell you which one is needed.
