Description

cryptoflex-tool is used to manipulate PKCS data structures on Schlumberger Cryptoflex smart cards. Users
       can create, list and read PINs and keys stored on the smart card. User PIN authentication is performed
       for those operations that require it.

Name

       cryptoflex-tool - utility for manipulating Schlumberger Cryptoflex data structures

Options

--app-dfnum, -anum
           Specifies the DF to operate in

       --create-key-filesarg, -carg
           Creates new RSA key files for arg keys

       --create-pin-filesid, -Pid
           Creates new PIN file for CHVid--exponentexp, -eexp
           Specifies the RSA exponent, exp, to use in key generation. The default value is 3.

       --generate-key, -g
           Generate a new RSA key pair

       --key-numnum, -knum
           Specifies the key number to operate on. The default is key number 1.

       --list-keys, -l
           Lists all keys stored in a public key file

       --modulus-lengthlength, -mlength
           Specifies the modulus length to use in key generation. The default value is 1024.

       --prkey-fileid, -pid
           Specifies the private key file id, id, to use

       --pubkey-fileid, -uid
           Specifies the public key file id, id, to use

       --read-key, -R
           Reads a public key from the card, allowing the user to extract and store or use the public key

       --readerarg, -rarg
           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.

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

       --verify-pin, -V
           Verifies CHV1 before issuing commands

       --wait, -w
           Causes cryptoflex-tool to wait for a card insertion.
