NAME
pkcs15-tool - utility for manipulating PKCS #15 data structures on smart cards and similar
security tokens
SYNOPSIS
pkcs15-tool [OPTIONS]
DESCRIPTION
The pkcs15-tool utility is used to manipulate the PKCS #15 data structures on smart cards
and similar security tokens. Users can list and read PINs, keys and certificates stored on
the token. User PIN authentication is performed for those operations that require it.
OPTIONS
--version,
Print the OpenSC package release version.
--aid aid
Specify in a hexadecimal form the AID of the on-card PKCS#15 application to bind to.
--auth-id id, -a id
Specifies the auth id of the PIN to use for the operation. This is useful with the
--change-pin operation.
--change-pin
Changes a PIN or PUK stored on the token. User authentication is required for this
operation.
--dump, -D
List all card objects.
--list-info
List card objects.
--list-applications
List the on-card PKCS#15 applications.
--list-certificates, -c
List all certificates stored on the token.
--list-data-objects, -C
List all data objects stored on the token. For some cards the PKCS#15 attributes of
the private data objects are protected for reading and need the authentication with
the User PIN. In such a case the --verify-pin option has to be used.
--list-keys, -k
List all private keys stored on the token. General information about each private key
is listed (eg. key name, id and algorithm). Actual private key values are not
displayed. For some cards the PKCS#15 attributes of the private keys are protected for
reading and need the authentication with the User PIN. In such a case the --verify-pin
option has to be used.
--list-secret-keys
List all secret (symmetric) keys stored on the token. General information about each
secret key is listed (eg. key name, id and algorithm). Actual secret key values are
not displayed. For some cards the PKCS#15 attributes of the private keys are protected
for reading and need the authentication with the User PIN. In such a case the
--verify-pin option has to be used.
--list-pins
List all PINs stored on the token. General information about each PIN is listed (eg.
PIN name). Actual PIN values are not shown.
--list-public-keys
List all public keys stored on the token, including key name, id, algorithm and length
information.
--short -s
Output lists in compact format.
--no-cache
Disables token data caching.
--clear-cache
Removes the user's cache directory. On Windows, this option additionally removes the
system's caching directory (requires administrator privileges).
--clear-cache
Removes the user's cache directory. On Windows, this option additionally removes the
system's caching directory (requires administrator privileges).
--output filename, -o filename
Specifies where key output should be written. If filename already exists, it will be
overwritten. If this option is not given, keys will be printed to standard output.
--raw
Changes how --read-data-object prints the content to standard output. By default, when
--raw is not given, it will print the content in hex notation. If --raw is set, it
will print the binary data directly. This does not affect the output that is written
to the file specified by the --output option. Data written to a file will always be in
raw binary.
--read-certificate cert
Reads the certificate with the given id.
--read-data-object cert, -R data
Reads data object with OID, applicationName or label. The content is printed to
standard output in hex notation, unless the --raw option is given. If an output file
is given with the --output option, the content is additionally written to the file.
Output to the file is always written in raw binary mode, the --raw only affects
standard output behavior.
--read-public-key id
Reads the public key with id id, allowing the user to extract and store or use the
public key.
--read-ssh-key id
Reads the public key with id id, writing the output in format suitable for
$HOME/.ssh/authorized_keys.
The key label, if any will be shown in the 'Comment' field.
--rfc4716
When used in conjunction with option --read-ssh-key the output format of the
public key follows rfc4716.
The default output format is a single line (openssh).
--test-update, -T,
Test if the card needs a security update
--update, -U,
Update the card with a security update
--reader arg
Number of the reader to use. By default, the first reader with a present card is used.
If arg is an ATR, the reader with a matching card will be chosen.
--unblock-pin, -u
Unblocks a PIN stored on the token. Knowledge of the Pin Unblock Key (PUK) is required
for this operation.
--verbose, -v
Causes pkcs15-tool to be more verbose. Specify this flag several times to enable debug
output in the OpenSC library.
--pin pin, --new-pin newpin --puk puk
These options can be used to specify the PIN/PUK values on the command line. If the
value is set to env:VARIABLE, the value of the specified environment variable is used.
By default, the code is prompted on the command line if needed.
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 prefer
passing the codes via an environment variable on an unsecured system.
--new-pin pin
Specify New PIN (when changing or unblocking)
--verify-pin
Verify PIN after card binding and before issuing any command (without 'auth-id' the
first non-SO, non-Unblock PIN will be verified)
--test-session-pin
Equivalent to --verify-pin with additional session PIN generation
--wait, -w
Causes pkcs15-tool to wait for a card insertion.
--use-pinpad
Do not prompt the user; if no PINs supplied, pinpad will be used.
