python - Custom user authentication. How is it done, with the best practices? -

-

I am using Google engine app with Python. I want to add custom user authentication How is this done with best practices?

I need custom authentication because the app is built in Flex and I do not want to redirect to an HTML page.

User value object is like this: 

  Class User (db.Model): email = db.EmailProperty (required = true, indexed = true) masked_password = db. StringProperty (required = true) # Maybe more things here

I would like to mask the password, is there a function built in some GAE?

Then, how do I remember the current user? Through seasons and cookies? Or what else?

password:

password handling Good way is the result of a hash of a random salt value and password for every user + salt.

When the user wants to login, calculate the hash (password + salt) and see if that was the value you had set when you originally set the password. This idea is never ever used to store passwords in the claytext and two users with the same password will have the same head value.

You can find many examples on this online and SO.

Sessions:

Many ways to apply sessions and use cookies are popular. I suggest that you use a library already available for this purpose. Look at this.

Obfuscating Python code? -

I'm looking for a way to hide my Python source code. print "Hello World!" How can I encode this example so that it is not human-readable? I have been asked to use Base 64 but I'm not sure how. itemprop = "text"> It is limited only, first level ambiguous resolution, but has built-in: byte-code in Python Is a compiler for: dragon-o-m py_compile & lt; Your program.py & gt; creates a .pyo file with a byte-code, and where the docstrings are removed, etc. You can rename .pyo with the .py extension, and python & lt; Your program.py & gt; runs as your program, but it does not have your source code. PS : If your program blur modules like this, you need to rename them with the .pyc suffix (I Not sure it will not break a day), or you can work with .pyo and run them with python -o ... .pyo ( Import should work). This will allow dragon to search your modules (otherwise, Python looks for the .py module).
