Re: Netscape Communicator 4.x sensitive informations in configuration file

[MightyE <mightye () mightye org>]

Although keeping the password plaintext in a configuration file isn't 
the best way to handle a password that software needs to remember, I do 
however want to point out that in order for programs to remember your 
password, they *must* store the password in some sort of reverseable 
obfuscation, meaning that once the obfuscation algorithm is known, the 
password is no more secure no matter how obfuscated it gets, as the 
software must at some point in time return it to a plaintext form in 
order to make use of it.

Obfuscating stored passwords only provides a minimal level of additional 
protection.  If you are using a system where someone has access to your 
configuration files (example: public computer lab in a library or 
college campus), then do *not* store your password on that machine.  If 
someone has the same access to that machine as you do, consider any 
information you store on it to be publicly available, and take 
appropriate precautions for sensitive information.
