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
--learn-card, -L
Cache PKCS #15 token data to the local filesystem. Subsequent
operations are performed on the cached data where possible. If the
cache becomes out-of-sync with the token state (eg. new key is
generated and stored on the token), the cache should be updated or
operations may show stale results.
--read-certificate cert, -r cert
Reads the certificate with the given id.
--list-certificates, -c
Lists all certificates stored on the token.
--list-pins
Lists all PINs stored on the token. General information about each
PIN is listed (eg. PIN name). Actual PIN values are not shown.
--change-pin
Changes a PIN stored on the token. User authentication is required
for this operation.
--unblock-pin, -u
Unblocks a PIN stored on the token. Knowledge of the Pin Unblock
Key (PUK) is required for this operation.
--list-keys, -k
Lists 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.
--list-public-keys
Lists all public keys stored on the token, including key name, id,
algorithm and length information.
--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.
--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.
--no-cache
Disables token data caching.
--pin-id pin, -a pin
Specifies the auth id of the PIN to use for the operation. This is
useful with the --change-pin operation.
--reader num
Forces pkcs15-tool to use reader number num for operations. The
default is to use reader number 0, the first reader in the system.
--verbose, -v
Causes pkcs15-tool to be more verbose. Specify this flag several
times to enable debug output in the OpenSC library.
