Encrypt & Decrypt Password And Store In MS Access DB

I am trying to encrypt the password and then store in Access DB. I have check out already existing threads on Sitepoint and read the artile at 15second.com (Password Encrypt/Decrypt using MDI ). It works for SQLServer. I tried it. It works..

But i am using MS Access Database, and it doesn't have any binary data type in it. So MDI is not working for me here. I havn't find any help.

I am looking for your help now as i have give it up and this thread is the only hope for me now. I need to Encrypt/Decrypt the password while using Access at backend.

Encrypt Cookie (password)

Is there a built in fucntion in VBS that encrpyts information? I've never heard of it...

Anyways, I need to encrypt my user's cookie password, and username, so people can't read it very well...i.e. "173dfhal294" etc...

I check it against the database, so I also need to decrypt it also...

Can I make a function? (of course I can, but what would it look like?)

MS Access Password

I have password protected my Access database. I have ASP code that does not include in the password, I am not sure where to place it in the code - and every time it runs it comes up with an 500 internal server error message.


Here is a sample of the code:

.......................................
dim Conn, rs
set adoCn=server.createobject("ADODB.Connection")
adoCn.open "Provider=Microsoft.Jet.OLEDB.4.0;Persist Security Info=True;Data Source=" & server.mappath("fpdb/database.mdb")
set rs=createobject("adodb.recordset")

Validate Username And Password From Access Database

I am trying to create a "Members Only" section of my website. I have an Access Database to store usernames and passwords and I am using Frontpage 2003.

I have very little ASP experience and am having trouble finding some help on this subject that is understandable. I already have a global.asa file on the site because I currently have a page with a form that writes to the database.

What I would like to know is how to setup a login screen to get to the members only side of the site which will validate against the password table in the database.

I am working on a CMS website which uses a access database.

When a user adds a page a record is added to a table in the database. The user choses the page style from a selection of 7 or 8 layouts.

I have been asked to find out if I can password protect one of those pages??

I have tried a few sites but not found much. The it has been done before is to add a password protected layout and build a login area into the site.

The effect i want is for the user to click the page and a username and password box will apear?

Individually Password Protect Multiple Directories? Password Expiration?

I have a client who wants to password protect a learning course that is set up in modules. Each module needs to have it's own password protection so users can only access them as they progress through the course.

Each user should have their own password (for each module) and, said client would like the password to expire for the user at some (predetermined?) point. Is this possible? It seems like a lot (in terms of setup), but I don't know much about password stuff.

If it is possible, can someone give me an overview of how it works (theoretically) or where to find more specific info on setting something like this up (in ASP.net)

If it isn't possible, can someone suggest what is more reasonable in terms of protecting the modules?

Encrypt Codes

Does anyone out there know how to encrypt the entire ASP file? That means when a person tries to view my ASP source code, it will display as rubbish. Can't use Script Encoder (srcenc.exe) cause out there in the market exist a freeware Script Decoder (scrdec.exe) which can easily decode back the file to its original state.

When using the QueryString of the request object the actual values are exposed to the viewer of the site and often user pickup on these values and start changing them . This can lead user to see data that they are not supposed to or even data that may be erroneous.

Is there an easy way to encrypt the querystring values that get displayed on the location bar / other than not using querystring. Can I use java script to disable the status bar, at the bottom of the page to not expose the URL's of various links on a page?
