I am really not good at C, but I took a look at the sources of GPA, specifically the change_pin function in cm-openpgp.c, and it looks like GPA is using assuan protocol through gpgme here:
char command[100]; snprintf (command, sizeof command, "SCD PASSWD%s %d", reset_mode? " --reset":"", pinno+1); err = gpgme_op_assuan_transact_ext (gpgagent, command, NULL, NULL, NULL, NULL, NULL, NULL, &operr); I hadn't thought of that possibility. Python-GPG should support this, too - take a look at assuan.py in the examples folder. But I haven't yet found any documentation of the assuan commands you need here. This probably isn't as easy as a Python programmer might expect... Andreas
