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.

--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.

--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.
