Security :: Unable To Encrypt And Decrypt A Word Document?
Feb 12, 2011
I am working on encryption and decryption and able to encrypt and decrypt a Text file but not able to do the same for MS Word or any other file other than Text file. I am using a below code.
I'm teaching myself ASP.net. I'm creating an application that needs to store sensitive data. So, I found the following Blog to encrypt and decrypt data.
[URL]
I'm sure it's my app, but I wanted to make sure I'm not missing anything obvious. For some reason, my app and Encryptor only works when I pass < then 7 characters. If a pass 8, it doesn't commit to the database. If I remove Encryptor, the app will store
I have a HyperLink column in a gridview that when clicked should navigate the user to another page. I pass parameters to the page using a querystring. i want to encrypte the querystring when it passed to another page

User downloads a document from a specified site, saves to the local disk and fills in confidential details. When other users logs on to this computer and if they try to access the file, the document should not be accessible. Also consider that the document can be saved to a common server too, in which case, no one else other than the person who downloaded and filled the document should be able to open the document.
I have some sensitive data that will be stored in one of my database tables, how would I go about encrypting it while saving it to the database and then decrypting it when retreiving it? I am using VB.NET
I use MS SQL SERVER DB to store some servers' info with help of ASP.NET application and I want to know the strong way to encrypt and decrypt server's passwords and store them in that DB.
provide me the way in details + code since I didn't deal with encryption before..
I have search all around the internet and still have not found a solution for this problem. I have successfully been able to make a data grid hyperlink and encrypt the query string coming from that link. The problem that I am having is trying to decrypt the query string. When I try to decrypt it I get an error of "Invalid character in a Base-64 string."I know this means that I have a white space or an Invalid character somewhere, but for the life of me I don't know where. Futhermore I try this same code without the datagrid and replace it with just regular textboxes that passes querystrings to the next page and the code work perfectly.
I'm all set on the server side with the RSA key pair installed. Where I'm hung up is trying to get the job done on the web.config file ... can't seem to get the aspnet_regiis command string right. I am using the command string provided by the web host (DiscountAsp.net). Most (all) of the examples I read use a website on the development machine. I actually registered my project in IIS and tried that but it didn't work. In any case I would rather not have to go to the hassle of registering a project in IIS anyway if I can avoid it.
Details:
My web application project is in a folder on my local machine:
D:Projects<project name>
This is most recent (failed) attempt to use aspnet_regiis:
Is it possible to just do this manually by looking at the NetFrameworkConfigurationKey_xxxxx.xml file and entering the values? Seems like it should be do-able except I'm not sure how to parse the xml file for the correct values.
On a related note, when I add the following code to web.config it "announces" that "The keyContainerName attribute is not allowed". Ditto useMachineContainer
