security - The best way to create log-in realm in PHP -

-

I can do the login area in PHP and the way I do it by setting a session variable and checking that Whether the session variable is set or not on each restricted page, I check whether a certain session variable is set (or equal to a certain value). If not, I will send the user back to the login page. What is the best way to do this? Is there a more secure way to do this?

There are answers to people with more safety.

Keep it low, you should think of SSL and other things like password hashing ...

Hope it helps :)

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.

This will allow dragon to search your modules (otherwise, Python looks for the .py module).
