Is there a way for an assembly to enumerate all the permissions granted to it
by the runtime?  For some reason I remember reading somewhere in the past
that you can't do this, but I wasn't sure.

I have a Windows Service running a BusinessObjectManager component on an
application server that needs to impersonate the user that is accessing the
application server using a Smart Client application.
Presently the user is authenticated by getting their IIdentity by calling

AuthenticationTypes.None is the default authentication type for
DirectoryEntry.  But, what does "none" actually mean???  
When I set it, the system still seems to be authenticating with the
credentials of the calling thread.  Does that mean that

I can't seem to understand what a linkdemand for a principalpermission means?
If linkdemands are satisfied at JIT phase, how can it figure out the current
principal before running the code?
For example, if I was going to use windowsprincipals to make RBS decisions,

I have an MD5 hash, all 16 bytes of it, and I would like to store this
as a number as opposed to a byte array or the conventional 32 character
hex encoded string. Any ideas or am I way off course?
Thanks

WHAT SHOULD I DO IF I WANT TO AUTHENTICATE THE DOWNLODING USER?
I AM USING ASP.NET AND C# TO CREATE MY WEBPAGES.
THE SCENARIO IS SOME WHAT LIKE THIS...
1)

hint me with a class name or namespace that could be able to load a
certificate file of various formats to memory.
Many thanks

Hi
I'm trying to check a file for its security permissions to determine if it
is writeable or not.
The code looks like that:

I posted in this forum not long ago regarding encryption. After some
useful feedback and further reading I have come up with a strategy that
I think will work. I'm interested in feedback and any suggestions. Here
is my scenario.

Is there a way to get the password of the principal currently executing the
assembly?
Thanks in advance.

Hi, All!
Following code works on Windows XP SP2/SP1 (eng, IE 6.0.2900.2180), but does
not work on Windows 2000 SP4 (eng, IE 5.00.3700.1000). On both system .NET
Framework 1.1.4 is installed.

I'm under the impression that the effective permissions granted to any assembly subject to CAS, will be the "minimum settings" when traversing through the permission tree.
let say:
[GROUP_A_1]
   PermissionSet: Execution

I've not looked at encryption much in the past so I am relatively new
to it.
I am developing a commercial application in which I wish to store
various connection strings in some type of file. For security purposes
