If you have a version 2 card, this is possible. WARNING: Don't run the commands given below on version 1 cards - you will brick the card. 1. First you have to lock the PIN by decremeting the retry counters. I do it this way: $ gpg-connect-agent --hex > scd apdu 00 20 00 81 08 40 40 40 40 40 40 40 40 D[0000] 69 82 i. OK > scd apdu 00 20 00 81 08 40 40 40 40 40 40 40 40 D[0000] 69 82 i. OK > scd apdu 00 20 00 81 08 40 40 40 40 40 40 40 40 D[0000] 69 82 i. OK > scd apdu 00 20 00 81 08 40 40 40 40 40 40 40 40 D[0000] 69 83 i. > scd apdu 00 20 00 83 08 40 40 40 40 40 40 40 40 D[0000] 69 82 i. OK > scd apdu 00 20 00 83 08 40 40 40 40 40 40 40 40 D[0000] 69 82 i. OK > scd apdu 00 20 00 83 08 40 40 40 40 40 40 40 40 D[0000] 69 83 i. The status code 6983 says that the PIN is locked. I use a PIN of "@@@@@@@@" which is very likey invalid. 2. You terminate the card and activate it again: > scd apdu 00 e6 00 00 D[0000] 90 00 .. OK > scd apdu 00 44 00 00 D[0000] 90 00 .. OK > bye OK closing connection > Remove the card and insert it again. That's all. gpg --card-status shows a fresh card. To make things easier you may send the lines below as input to gpg-connect-agent (store them in a file and run "gpg-connect-agent < FILE"). ====== /hex scd serialno scd apdu 00 20 00 81 08 40 40 40 40 40 40 40 40 scd apdu 00 20 00 81 08 40 40 40 40 40 40 40 40 scd apdu 00 20 00 81 08 40 40 40 40 40 40 40 40 scd apdu 00 20 00 81 08 40 40 40 40 40 40 40 40 scd apdu 00 20 00 83 08 40 40 40 40 40 40 40 40 scd apdu 00 20 00 83 08 40 40 40 40 40 40 40 40 scd apdu 00 20 00 83 08 40 40 40 40 40 40 40 40 scd apdu 00 20 00 83 08 40 40 40 40 40 40 40 40 scd apdu 00 e6 00 00 scd apdu 00 44 00 00 /echo card has been reset to factory defaults ===== gpg-connect-agent has a complete scripting language, you may use it to write a more robust script with error checking etc. Salam-Shalom, Werner -- Die Gedanken sind frei.
