NAMEwestcos-tool − utility for manipulating data structures on westcos smart cards

SYNOPSISwestcos−tool [OPTIONS]

DESCRIPTIONThe 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 pin, −x pin −−puk−value puk, −y 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​. −−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 arg, −r 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 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​.
