Bending Gnome Keyring with Python – Part 3

In the last post I've shown how to create keyrings using python and mentioned a slightly difference from the "seahorse password storing process". Well, it happens that, when we start to dig this difference isn't so small. Using seahorse every keyring item is created with the "Update if Exists" flag as False, so you can create identical keyring items. This is not a safe approach and can result in an inconsistent keyring. But as we use the "Update if Exists" flag set as True, something unexpected happens:

#!/usr/bin/env python

import gnomekeyring as gk
import glib

APP_NAME = 'MyApp'
KEYRING_NAME = 'MyKeyring'

glib.set_application_name(APP_NAME)

keyrings = gk.list_keyring_names_sync()

# If this keyring already exist, let's remove it
if KEYRING_NAME in keyrings:
# Gnome Keyring Daemon may ask for a password here
gk.delete_sync(KEYRING_NAME)

# If anyone asks, the password is 'mypasswd'
gk.create_sync(KEYRING_NAME, 'mypasswd')

id = gk.item_create_sync(KEYRING_NAME, gk.ITEM_GENERIC_SECRET, 'magnun@Neptune:22', {'application':APP_NAME}, 'passwd', True)
print 'New host added (key=%i)'%(key)

id = gk.item_create_sync(KEYRING_NAME, gk.ITEM_GENERIC_SECRET, 'guest@Neptune:22', {'application':APP_NAME}, 'passwd', True)
print 'New host added (key=%i)'%(key)

id = gk.item_create_sync(KEYRING_NAME, gk.ITEM_GENERIC_SECRET, 'magnun@Jupiter:22', {'application':APP_NAME}, 'passwd', True)
print 'New host added (id=%i)'%(id)

Save this as my_keyring_creator.py and run it...
