Question

the pickled file i create using this method is readable in text editor if we forcibly open it,

import pickle,os
print os.path.split(__file__)[0]
storloc= os.path.normpath(os.path.join(os.path.split(__file__)[0],"test.pkl"))

newD={"String":"this is the world", "int":1,"float":1.5}
print newD
print storloc
d = open(storloc, 'wb')
pickle.dump(newD,d)
d.close()

how to make pickled file(test.pkl) unreadable in any text editor?

Answer 1

Attempting to make a simple format such as Python pickles safe for passwords is a fools game.

Use the keyring package instead and leave it to the OS to store your password safely.

import keyring

username = # Obtain a stored username or ask the user
password = keyring.get_password('your_application_name', username)

if password is None or verify_password_failed:
    password = # Obtain a password from the user
    keyring.set_password('your_application_name', username, password)

The keyring package uses the OS-supplied keyring (OS X, Windows, KDE, Gnome), but will fall back to an encrypted store of it’s own if necessary.
