1MMC Password Protection Reference UI 2------------------------------------ 3 4This is a simple text-mode reference UI for the MMC password protection 5support, written in shell script. It's very simple and does not hash nor cache 6passwords. 7 8It's composed of the following files: 9 10- ask_password.sh: get the password from userspace. It's called when unlocking 11 the card or assigning a new password to an unlocked card. 12- change_password.sh: used to change the password from a unlocked card. 13- forced_erase.sh: used to force-erase a card, usually when the user has forgot 14 the password and wants to unlock the card. NOTE: all the card's contents are 15 lost when using this option! It only works for _locked_ cards. 16- remove_password.sh: used to remove the passwor from a card previously unlocked. 17 18Setting up 19---------- 20 211) Install the keyutils package available from http://people.redhat.com/~dhowells/keyutils/ 222) Install this package: 23 24 252) Add the following lines to /etc/request-key.conf (remember to remove any 26previous mmc lines): 27 28create mmc mmc:key unlock /usr/share/keyutils/ask_password.sh %k %S 29create mmc mmc:key assign /usr/share/keyutils/assign_password.sh %k %S 30 31Using it 32-------- 33 341) Unlocking a card: 35 36keyctl request2 mmc mmc:key unlock 37 382) Assigning a password to an unlocked card: 39 40keyctl request2 mmc mmc:key assign 41 423) Changing the password (card must be unlocked first): 43 44/usr/share/keyutils/change_password.sh 45 464) Removing the password (card must be unlocked first): 47 48/usr/share/keyutils/remove_password.sh 49 505) Force erase card (card must be LOCKED): 51 52/usr/share/keyutils/force_erase.sh 53 54Contact Info 55------------ 56 57Any comments or suggestions regarding these scripts should be sent to: 58 59Anderson Briglia <anderson.briglia@indt.org.br> 60Anderson Lizardo <anderson.lizardo@indt.org.br> 61Carlos Eduardo Aguiar <carlos.aguiar@indt.org.br> 62
