Re: About a Config file on a UNIX server




One thing I think is real import to note here, particularly when
it comes to passwords. UNIX systems ship with a useful library function
called 'crypt()', without going into details this is a one-way-hash, -
its computationally extremely expensive to reverse a one-way-hash so
passwords can be stored in world readable files (such as /etc/passwd)
without great security risk. UNIX webservers follow this convention and
you will see that the base64 encoding of user password in many htpasswd
and other files use crypt().

Now enter windows NT. No crypt(). The apache team choose to just 
store passwords in base64 format (effectively plain text) in thier
windows ports. I figured *what-the-hell* and did this also in Pi3Web.
It should be clearly understood that this is not the slightest bit 
secure. The same way that using a username/password pair for
basic authentication under http (as opposed to https) is also not
secure.
