Pyinstaller Keyring Windows 32 bit

Question

I have the following python test code:

import keyring
print(keyring.get_keyring())
keyring.set_password("a","b","c")
print(keyring.get_password("a","b"))

If I run this code using a 32 bit python or a 64 bit one I obtain the following output (as expected):

<keyring.backends.Windows.WinVaultKeyring object at 0x00000187B7DD6358>
c

My purpose is to build two standalone executable (32bit and 64bit): in order to achieve that I'm using pyinstaller and the following command (test.py is the name of the file containing the python code shown above)

pyinstaller --onefile test.py

If I run the 64 bit exe I obtain the following output (as expected):

<keyring.backends.Windows.WinVaultKeyring object at 0x00000187B7DD6358>
c

Instead, if I run the 32 bit exe I obtain the following output:

<keyring.backends.fail.Keyring object at 0x05463ED0>
Traceback (most recent call last):
  File "test.py", line 3, in <module>
    keyring.set_password("a","b","c")
  File "site-packages\keyring\core.py", line 47, in set_password
  File "site-packages\keyring\backends\fail.py", line 23, in get_password
RuntimeError: No recommended backend was available. Install the keyrings.alt package if you want to use the non-recommended backends. See README.rst for details.
[2732] Failed to execute script test

Does anyone know what is going on?

Thanks,

Daniele

How do you obtain your 32 bit executable? If you want your final exe to be executable on both 32 and 64 bits, you should install `pyinstaller` with your 32 bits version of python and produce the exe from there. — Jacques Gaudin, May 31 '18 at 14:13
I'm using a 32 bits python to produce the executable: anyway I just solved the issue using an alternate keyring (see the answer below). — Daniele Milani, May 31 '18 at 15:54

Solved using an alternate keyring backend. If I change my code from:

import keyring
print(keyring.get_keyring())
keyring.set_password("a","b","c")
print(keyring.get_password("a","b"))

to:

import keyring
from keyrings.alt import Windows
keyring.set_keyring(Windows.RegistryKeyring())
print(keyring.get_keyring())
keyring.set_password("a","b","c")
print(keyring.get_password("a","b"))

it works.

Setting up the keyrings.alt file from the Keyring Github page does seem to work, and would explain why this was only an issue in Keyring>12, since it was included in the Module before that. I was also able to work around it by installing pip install pywin32 and running the following additions:

import keyring
import win32timezone
from keyring.backends import Windows
keyring.set_keyring(Windows.WinVaultKeyring())
print(keyring.get_keyring())
keyring.set_password("a","b","c")
print(keyring.get_password("a","b"))
