The IV is chosen randomly as well. All the stored passwords are encrypted at once. Any keyrings using the old format will be automatically converted to the new format (but will no longer be compatible with 0.9 and earlier). The user's password is no longer limited to 32 characters. PyCrypto 2.5 or greater is now required for this keyring. See: http://pypi.python.org/pypi/keyring#id2 https://bugs.launchpad.net/ubuntu/+source/python-keyring/+bug/1004845 Thanks, Marc. -- Marc Deslauriers Ubuntu Security Engineer | http://www.ubuntu.com/ Canonical Ltd. | http://www.canonical.com/
