Security :: Getting "Invalid Data" While DES-decrypting?
Mar 10, 2011
I'm trying a simple encryption procedure, encrypting/decrypting a HEX value. Encryption seems to work fine: result of encryption is "85772B6784BC1505". While trying to decrypt I get an "Invalid data"-exception.
CODE:
Dim x1 As UInt64 = DES.DES_EncryptCode("&H" & "0123456789ABCDEF")
Dim x2 As UInt64 = DES.DES_DecryptCode(x1)
Private Shared KEY_64() As Byte = {7, 6, 5, 4, 3, 2, 1, 0}
Private Shared IV_64() As Byte = {0, 1, 2, 3, 4, 5, 6, 7}

I have a problem hopefully someone out there will steer me in the right direction.
I have a web application that I am going to put on a standalone cd - currently the data is "Safe" because the database is in in the app folder and the code is located in the codebehind.
My problem is i'm putting this on a CD as a standalone site, anyone can access the database, or find the XML....
Is there a way to generate an encrypted Database / XML Page, that is complied with the CD, that the program can decrypt and access with a embedded key?

I have an external site developed in php that send me a string cripted with this php function:
const SALT = "chiave";
public static function myEncrypt($text)
{
return rawurlencode(base64_encode(mcrypt_encrypt(MCRYPT_RIJNDAEL_256, self::SALT, $text, MCRYPT_MODE_ECB, mcrypt_create_iv(mcrypt_get_iv_size(MCRYPT_RIJNDAEL_256, MCRYPT_MODE_ECB), MCRYPT_RAND))));
}
and then I need to decrypt this in asp.net.
How can I do?

I received some code, a small c# asp.net application which manually posts a shared username/pwd to a 3rd party website for auto-logins from our intranet site. During transit the password is encrypted, but not within the application. Within this application a namevaluecollection is used and the username and password are hard coded. Originally the thought was, who cares if its hard coded because its shared between everyone anyway. Now we want to encrypt the username and password from within the application. I'm not sure the best way to accomplish the goal of making sure the password is encrypted "at rest". Normally I've seen passwords stored and encrypted within a database. I know we'll obviously have to move the password out of the application and store it somewhere else, I'm just not sure where. Do we move the username and pwd to the web.config file? I really am not sure the best way to approach this.

I have an internal web application which uses a custom encryption class to convert strings to varbinary(50) columns in SQL. When I display the table in a GridView, I want to use the RowDataBound event to decrypt the encrypted column back to a string to display.
Currently I have the following in my RowDataBound event:
[Code]....
This throws an exception when I try to load the page: TransformFinalBlock - Length of the data to decrypt is invalid.
I have tried just fetching the data from SQL in my query but the e.Row.Cells(3).Text evaluates to System.Byte[], so I tried using CAST([EncrytedColumn] AS varchar(50)) to convert the varbinary(50) to varchar(50), but this still resulted in the same exception being thrown.
My only solution so far has been to manually fetch the SQL data into a DataTable and decrypt the column before displaying it in the GridView, but I prefer the automated method of binding the SQLDataSource to the GridView.

I use some code to check if people are in a group in Active Directory. If the group has an '&' in it then I run into problems.
DirectoryEntry entry = new DirectoryEntry("LDAP://adserver/CN=" + theGroup + ",OU=Distribution Groups,OU=Accounts,DC=ourdomain,DC=net");
I tried to do
theGroup = theGroup.Replace("&",
"\&");
but it's the same problem.

Since installing the security patch for the ASP.NET Oracle Padding vunerability any user that was keeping themselves logged in to our site is getting error messages when hitting any page.

I have IIS on S2k8 and a website with Windows Authentication only.
I can easily reproduce the following scenario, where HttpContext.Current.Request.LogonUserIdentity.Name has a bad value:
Login to website using FireFox, using an Active Directory account "user" (I could use IE to reproduce the same, but it's a few extra steps)Display <%=System.Web.HttpContext.Current.Request.LogonUserIdentity.Name%> on the pageIt shows "DOMAINuser", which is correctI go into Active Directory and rename the account to be "userX" instead of "user" (both SAMAccountName & UPN)Restart FireFoxLogin to website using "userX" accountThe page still shows "DOMAINuser", instead of the expected "DOMAINuserX"
It seems almost as if IIS has cached the old username and it's not showing me the new one, even though I explicitly enter it in the login prompt.

A bit more background info as suggested:I'm finsihing of an Intranet CMS web app where I have to use the products API (ASP.NET based). Because of time constraints and issues with Windows authen' I need another way to ensure staff do not need to re login everytime they visit the site to view personalised content. The way it works is that once a user logs in (username/password), a Session ID storing a new different Security context value is generated that is used to display the personalised content. The API login method called uses the username and password as parameters. The only way I can think of automatically logging in the next time the staff visits the site is by storing the password in a enrypted cookie and checking of its existing when the site is visited and then calling the API login method using the username and decrypted password cookie values.Any other ideas as an alternative welcomed.'m using some code found on the web to encrypt and decrypt a password string. It encrypts fine but when it calls the code below to decrypt the string it throws the error "Length of the data to decrypt is invalid" How can I resolve this?
System.Text.Encoding enc = System.Text.Encoding.ASCII;
byte[] myByteArray = enc.GetBytes(_pword);
SymmetricAlgorithm sa = DES.Create();

I'm working on an ASP.NET project for the first time in about three years; in the meantime I've been working with Python/Django, PHP and Obj-C. Anyways, picked it right back up... except something that is totally killing me right now, and I have a feeling it must be staring me in the face:
I'm trying to bind to an LDAP server, for the purpose of authenticating users. The way it works here is, you bind on your own credentials, use that to find the Distinguished Name of the user you're authenticating, then you bind again on their DN and their password. If the bind is successful, the password was correct and the user can be authenticated.
Here's the problem - the first bind (on the fixed credentials, the ones with the ability to search for users and their subtrees) works fine. The search works fine. The second bind fails, no matter what, with the LDAP error INVALID_CREDENTIALS. This happens even when completely valid credentials are supplied.
Here's the code, with the usernames and passwords redacted, of course...

I have a content-sensitive firewall between my clients and my server. If we exclude SSL solution (it's not available in my case) then I was thinking of a javascript library which encrypts custom fields at client-side and a .NET class decrypts them at server-side. Is there any solution out of the box (maybe a server control) ?
