NAME
pkcs15-init - smart card personalization utility
DESCRIPTION
The pkcs15-init utility can be used to create a PKCS #15 structure on a
smart card, and add key or certificate objects. Details of the
structure that will be created are controlled via profiles.
The profile used by default is pkcs15. Alternative profiles can be
specified via the -p switch.
PIN USAGE
pkcs15-init can be used to create a PKCS #15 structure on your smart
card, create PINs, and install keys and certificates on the card. This
process is also called personalization.
An OpenSC card can have one security officer PIN, and zero or more user
PINs. PIN stands for Personal Identification Number, and is a secret
code you need to present to the card before being allowed to perform
certain operations, such as using one of the stored RSA keys to sign a
document, or modifying the card itself.
Usually, PINs are a sequence of decimal digits, but some cards will
accept arbitrary ASCII characters. Be aware however that using
characters other than digits will make the card unusable with PIN pad
readers, because those usually have keys for entering digits only.
The security officer (SO) PIN is special; it is used to protect meta
data information on the card, such as the PKCS #15 structure itself.
Setting the SO PIN is optional, because the worst that can usually
happen is that someone finding your card can mess it up. To extract any
of your secret keys stored on the card, an attacker will still need
your user PIN, at least for the default OpenSC profiles. However, it is
possible to create card profiles that will allow the security officer
to override user PINs.
For each PIN, you can specify a PUK (also called unblock PIN). The PUK
can be used to overwrite or unlock a PIN if too many incorrect values
have been entered in a row.
MODES OF OPERATION
Initialization
This is the first step during card personalization, and will create the
basic files on the card. To create the initial PKCS #15 structure,
invoke the utility as
pkcs15-init --create-pkcs15
You will then be asked for several the security officer PIN and PUK.
Simply pressing return at the SO PIN prompt will skip installation of
an SO PIN.
If the card supports it, you can also request that the card is erased
prior to creating the PKCS #15 structure, by specifying the
--erase-card option.
User PIN Installation
Before installing any user objects such as private keys, you need at
least one PIN to protect these objects. you can do this using
pkcs15-init --store-pin --id " nn
where nn is a PKCS #15 ID in hexadecimal notation. Common values are
01, 02, etc.
Entering the command above will ask you for the user’s PIN and PUK. If
you do not wish to install an unblock PIN, simply press return at the
PUK prompt.
To set a label for this PIN object (which can be used by applications
to display a meaningful prompt to the user), use the --label command
line option.
Key generation
pkcs15-init lets you generate a new key and store it on the card. You
can do this using:
pkcs15-init --generate-key " keyspec " --auth-id " nn
where keyspec describes the algorithm and length of the key to be
created, such as rsa/512. This will create a 512 bit RSA key.
Currently, only RSA key generation is supported. Note that cards
usually support just a few different key lengths. Almost all cards will
support 512 and 1024 bit keys, some will support 768 or 2048 as well.
nn is the ID of a user PIN installed previously, e.g. 01.
In addition to storing the private portion of the key on the
card,pkcs15-init will also store the the public portion of the key as a
PKCS #15 public key object.
By default, pkcs15-init will try to use the card’s on-board key
generation facilities, if available. If the card does not support
on-board key generation, pkcs15-init will fall back to software key
generation.
Private Key Download
You can use a private key generated by other means and download it to
the card. For instance, to download a private key contained in a file
namedokir.pem, which is in PEM format, you would use
pkcs15-init --store-private-key okir.pem --id 45 --auth-id 01
If the key is protected by a pass phrase, pkcs15-init will prompt you
for a pass phrase to unlock the key.
In addition to storing the private portion of the key on the
card,pkcs15-init will also store the the public portion of the key as a
PKCS #15 public key object.
Note the use of the --id option. The currentpkcs15 profile defines two
key templates, one for authentication (key ID 45), and one for
non-repudiation purposes (key ID 46). Other key templates will probably
be added in the future. Note that if you don’t specify a key ID,
pkcs15-init will pick just the first key template defined by the
profile.
In addition to the PEM key file format, pkcs15-init also supports DER
encoded keys, and PKCS #12 files. The latter is the file format used by
Netscape Navigator (among others) when exporting certificates to a
file. A PKCS #12 file usually contains the X.509 certificate
corresponding to the private key. If that is the case, pkcs15-init will
store the certificate instead of the public key portion.
Public Key Download
You can also download individual public keys to the card using
the--store-public-key option, which takes a filename as an argument.
This file is supposed to contain the public key. If you don’t specify a
key file format using the --format option,pkcs15-init will assume PEM
format. The only other supported public key file format is DER.
Since the corresponding public keys are always downloaded automatically
when generating a new key, or when downloading a private key, you will
probably use this option only very rarely.
Certificate Download
You can download certificates to the card using the--store-certificate
option, which takes a filename as an argument. This file is supposed to
contain the DER encoded X.509 certificate.
Downloading PKCS #12 bags
Most browsers nowadays use PKCS #12 format files when you ask them to
export your key and certificate to a file. pkcs15-init is capable of
parsing these files, and storing their contents on the card in a single
operation. This works just like storing a private key, except that you
need to specify the file format:
pkcs15-init --store-private-key okir.p12 --format pkcs12 --auth-id 01
This will install the private key contained in the file okir.p12, and
protect it with the PIN referenced by authentication ID 01. It will
also store any X.509 certificates contained in the file, which is
usually the user certificate that goes with the key, as well as the CA
certificate.
OPTIONS
--profile name, -p name
Tells pkcs15-init to load the specified general profile.
Currently, the only application profile defined ispkcs15, but
you can write your own profiles and specify them using this
option.
The profile name can be combined with one or more profile
options, which slightly modify the profile’s behavior. For
instance, the default OpenSC profile supports theopenpin option,
which installs a single PIN during card initialization. This PIN
is then used both as the SO PIN as well as the user PIN for all
keys stored on the card.
Profile name and options are separated by a + character, as in
pkcs15+onepin.
--card-profile name, -c name
Tells pkcs15-init to load the specified card profile option. You
will rarely need this option.
--create-pkcs15, -C
This tells pkcs15-init to create a PKCS #15 structure on the
card, and initialize any PINs.
--erase-card, -E
This will erase the card prior to creating the PKCS #15
structure, if the card supports it. If the card does not support
erasing,pkcs15-init will fail.
--generate-key keyspec, -G keyspec
Tells the card to generate new key and store it on the
card.keyspec consists of an algorithm name (currently, the only
supported name is RSA), optionally followed by a slash and the
length of the key in bits. It is a good idea to specify the key
ID along with this command, using the id option.
--store-private-key filename, -S filename
Tells pkcs15-init to download the specified private key to the
card. This command will also create a public key object
containing the public key portion. By default, the file is
assumed to contain the key in PEM format. Alternative formats
can be specified using --format. It is a good idea to specify
the key ID along with this command, using the --id option.
--store-public-key filename, -P filename
Tells pkcs15-init to download the specified public key to the
card and create a public key object with the key ID specified
via the --id. By default, the file is assumed to contain the key
in PEM format. Alternative formats can be specified using
--format.
--store-certificate filename, -X filename
Tells pkcs15-init to store the certificate given in filename on
the card, creating a certificate object with the ID specified
via the --id option. The file is assumed to contain the DER
encoded certificate.
--so-pin, --so-puk, --pin, --puk
These options can be used to specify PIN/PUK values on the
command line. Note that on most operation systems, any user can
display the command line of any process on the system using
utilities such as ps(1). Therefore, you should use these options
only on a secured system, or in an options file specified
with--options-file.
--passphrase
When downloading a private key, this option can be used to
specify the pass phrase to unlock the private key. The same
caveat applies here as in the case of the --pin options.
--options-file filename
Tells pkcs15-init to read additional options from filename. The
file is supposed to contain one long option per line, without
the leading dashes, for instance:
pin frank
puk zappa
You can specify --options-file several times.
--verbose, -v
Causes pkcs15-init to be more verbose. Specify this flag several
times to enable debug output in the OpenSC library.
