Yes, I'm well aware of these issues, but it's my personal address book
so I can avoid many/most of them.
So you assume that you'll never meet someone from another culture?
Okay. I'm pretty sure that counts as bigoted, but sure :)
Chris: I think that remark was uncalled for. You'd made a perfectly
valid point about names not always working how we think. At that point,
I think it's up to each person to decide their own approach based on
their own knowledge of their own circumstances.

He's free to assume that not one of his friends will be from any culture other than his own. It just happens to be a bigoted viewpoint. I wonder, would people treat it differently if the address book took a traditional binary view of gender, and required that everyone be precisely "male" or "female"? Would that be called bigoted, or is it perfectly reasonable to demand that all of your friends fit this? ChrisA -- https://mail.python.org/mailman/listinfo/python-list

The justification "it's *my* personal address book" is saying "none of *my* friends have weird names, so I'm fine". So, yeah, he did. This is a design flaw on par with assuming that a byte is identical to a character; you can pretend it so long as you don't get any "funny characters". And then you can blame the non-ASCII characters for breaking your program, or force someone's name to fit into your predefined scheme. ChrisA -- https://mail.python.org/mailman/listinfo/python-list

As of Python 3, we've finally moved beyond the notion that there are "weird characters" that don't fit into our nice tidy system where one character is the same as one byte. We need to give people's names the same courtesy. They are not "weird" names. They are 100% legitimate names that should be welcomed into any system that accepts names. (That said, though, I think it's not unreasonable to demand that names be represented entirely in Unicode - falsehood #11 - as it's extremely hard to deal with non-Unicode text. But you have to understand that you'll be asking some number of people to represent themselves differently for the convenience of your code.)

Which doesn't work at all for me as I want to:-
Sort on family/last name
Separate first and family name so I can write addresses etc.
I've lived in quite a few different places where names are not
formatted like ours. I'm aiming to add 'nameprefix' and 'namesuffix'
fields to handle different formats more completely, the layout I
showed here is just a prototype.

But you don't know whether he is using unicode or not. And if he is not, it still is his own personal address book and he is allowed to transliterate the names he enters any way he likes. If he has a French friend with the name "Pièrre", he is allowed to enter it as "Pjair" in his personal address book if he thinks that would help him to pronounce it more correctly. So he is not asking a number of people to represent themselves differently because this is not something for different people to use, it is his personal address book. -- Antoon Pardon. -- https://mail.python.org/mailman/listinfo/python-list

keyrings.cryptfile released on github
Hi,
since the PyCrypto ML is dead, I'm looking for advise/feedback from some
cryptography aware people.
I've released a keyring companion package today:
https://github.com/frispete/keyrings.cryptfile
Its primary purpose is a decent encrypted file backend for python keyrings.
As such, it uses manually parameterized argon2 hashes as KDF, and AES in OCB
mode as stream cipher (well, it just encrypts the password for a given
service/user name). Granted, the advantages of OCB are not /that/ crucial
here :wink:, but apart from technical factors, the exclusion of military uses
by its license is rather *attractive* from my POV(!). But I'm open for
discussions of course.
Still interested? Here we go:
To get you started, I expect you to have a python3 environment and git
available. You might want to provide the packages argon2-cffi, keyring,
pycryptodome and their dependencies (most notably SecretStorage and
cryptography, or use a local venv, but that will depend on a compiler and some
development packages.
Example session, create an encrypted keyring:
$ git clone https://github.com/frispete/keyrings.cryptfile
$ cd keyrings.cryptfile
$ pyvenv env
$ . env/bin/activate
(env) $ pip install -e .
[...] # should succeed, some development packages might be missing otherwise
(env) $ python3
Python 3.4.5 (default, Jul 03 2016, 12:57:15) [GCC] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> from keyrings.cryptfile.cryptfile import CryptFileKeyring
>>> kr = CryptFileKeyring()
>>> kr.set_password("service", "user", "secret")
Please set a password for your new keyring:
Please confirm the password:
>>> ^d
Second session, retrieve the stored secret from the keyring:
(env) $ python3
Python 3.4.5 (default, Jul 03 2016, 12:57:15) [GCC] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> from keyrings.cryptfile.cryptfile import CryptFileKeyring
>>> kr = CryptFileKeyring()
>>> kr.get_password("service", "user")
Please enter password for encrypted keyring:
'secret'
>>> ^d
Note, that the KDF might delay the {set,get}_password() operations for a
few seconds (~1 sec. on a capable system).
The resulting file is located here (by default) and might look similar to:
(env) $ cat ~/.local/share/python_keyring/cryptfile_pass.cfg

"salt": "ZAxHIuyjbtnNH3opL51ovA==\\n", "data": "Ob7gRImtyiRK\\n"}'
The items should be self explanatory. In theory, it should be considerable
hard to get back to the plain values of data without knowing the password.
Any cryptography experts attending?
What do you think? The class hierarchy is inherited from keyrings.alt, and
not exactly easy to follow, but the interesting parts are all in cryptfile,
which is quite brief.
I would be glad to hear something from you about my handling of cryptography.
Is it ready for the public in that form or should I better locked away? :wink:
TIA,
Pete
