WESTCOS-TOOL(1)

NAME
westcos-tool - utility for manipulating data structures on westcos smart cards

SYNOPSIS

westcos-tool [OPTIONS]

DESCRIPTION

The westcos-tool utility is used to manipulate the westcos data structures on 2 Ko smart cards / tokens. Users can create PINs, keys and certificates stored on the card / token. User PIN authentication is performed for those operations that require it.

OPTIONS

--change-pin, -n
    Changes a PIN stored on the card. User authentication is required for this operation.

--certificate file, -t file
    Write certificate file file in PEM format to the card. User authentication is required for this operation.

--finalize, -f
    Finalize the card. Once finalized the default key is invalidated, so PIN and PUK cannot be changed anymore without user authentication.

    Warning, un-finalized cards are insecure because the PIN can be changed without user authentication (knowledge of default key is enough).

--generate-key, -g
    Generate a private key on the card. The card must not have been finalized and a PIN must be installed (i.e. the file for the PIN must have been created, see option -i). By default the key length is 1536 bits. User authentication is required for this operation.

--help, -h
    Print help message on screen.

--install-pin, -i
    Install PIN file in on the card. You must provide a PIN value with -x.

--key-length length, -l length
    Change the length of private key. Use with -g.

--overwrite-key, -o
    Overwrite the key if there is already a key on the card.

--pin-value value, -x value
    Set value of PIN. If set to env:VARIABLE, the value of the environment variable VARIABLE is used.

--puk-value value, -y value
    set value of PUK (or value of new PIN for change PIN command see -n). If set to env:VARIABLE, the value of the environment variable VARIABLE is used.

--read-file filename, -j filename
    Read the file filename from the card. The file is written on disk with name filename. User authentication is required for this operation.

--reader num, -r num
    Specify the reader to use. By default, the first reader with a present card is used. If num is an ATR, the reader with a matching card will be chosen.

--unblock-pin, -u
    Unblocks a PIN stored on the card. Knowledge of the PIN Unblock Key (PUK) is required for this operation.

--verbose -v
    Causes westcos-tool to be more verbose. Specify this flag several times to enable debug output in the OpenSC library.

--wait, -w
    Wait for a card to be inserted.

--write-file filename, -k filename
    Put the file with name filename from disk to card. On the card the file is written in filename. User authentication is required for this operation.
