Make Encrypted String Same Length As Input String?
Nov 24, 2010I have a 15 digit string to encrypt.
I have tried using .NET's various encryption functions but all my encrypted strings are at least 24, 28 or 32 in length.
I have heard of CipherMode.CTS with Padding = None that produces the same length output as the input length but I can't seem to get the same result. I have toyed with the block-size, key-size and salt size.
I don't mind adding a digit to my input string to make it 16 in length.

Jan 25, 2011I need to design two apps who can interact with each other. The first app, App A needs to send an encrypted string over to App B and App B will have to decrypt it and do some stuff. How would I go about that?
App A - http://MachineA/default.aspx
App B - http://MachineB/default.aspx
I tried encrypting the data using AESCryptoServiceProvider and it returns a byte[]. Now how would I transfer it over to another application? Via query strings?
http://MachineB/default.aspx?data=<<EncryptedString>>
Query strings does not take a byte[] parameter. So I am clueless now.

Web Forms :: How To Read Encrypted Connection String In Role Manager
Jul 17, 2015i don't know how to use a Encrypted ConnectionString with RoleManager in ASP.NET This is code in Web.config.
<connectionStrings>

And in project I create a library to read web config
private const string ConnectionStringKey = "strConnectionString";
private readonly string SQLConnectionString =
Security.DecryptString(ConfigurationManager.ConnectionStrings[ConnectionStringKey].ConnectionString);
if I change my ConnectionString like this, it's working:
<add name="strConnectionString" connectionString="server=My-PCMSSQL2008; database=MyDB; uid=sa; pwd=passw0rd;"/>
But I want my ConnectionString Encrypted so i use

C# - Sending Encrypted Text In Url
Feb 11, 2011I have a very simple (rather stupid) question, I hope someone can clear my mind on this :)
I want to send an email to my site user once he clicks a button. This email will contain a link with the userID of a user in the link URL (as query param of a link).
Once the user clicks this email link, my server side code will parse and decrypt the userID query string key to get the user ID and perform some action on it.
I cannot use base64 encoding as it can be reversed and 'hackers' can get to know the real userID. I have to encrypt the ID but when I am using AES alogrithms for encryption, the encrypted text is not "understandable" by the browser, ie I cannot pass the encrypted userId text as a part of the URL because it contains un-encoded characters like "/" which the browser cannot by pass. One option I can think of is to base64 encode the encrypted text once I send it across via URL. Then I can bease64 decode and decyrpt it.
Is this approach better than using Uri.EscapeDataString() on the encyrpted text?
Using Encrypted Web.config File?
Jun 18, 2010My aim is to make the web.config not readable by external users, but my application should be able to access it. Is there any way to do this?
I have tried the following way, but how to set the application to use string instead of web.config?
I want to encrypt my web.config file so that others do not open the file using any editor like notepad. But my application should be able to use the same web.config file. I could encrypt the web.config file and decrypt it inside the application and I saved the entire web.config to a string file. Now I want to use this string variable instead of web.config(now in encrypted form, which cannot be accessed by the application).

Changing PasswordFormat From Encrypted To Hashed
Feb 9, 2011I'm finding surprisingly little information on converting an existing database from Encrypted passwords to Hashed passwords. (I was able to find a bit more information on converting the other way, but it wasn't of much help.)
As most people know, changing the passwordFormat setting in web.config only affects new users. I have a database with a couple of hundred users and I'd like to convert them to use hashed passwords without changing those existing passwords.

Web Forms :: Encrypted String Doesn't Match With Targeted String?
Feb 23, 2011i have created a encrypted string to match with a target string to pass it along with client URL for authentication. it doesn't match. here is an algorithm used to create a encrypted string.
text = "astringtobeencrypted";
string strglobalkey = "mytestglobalkey";
string hexivkey = "testing12345";
ebCryptLib.eb_c_Cipher ci = new ebCryptLib.eb_c_Cipher();
string strhex1 = ConvertStringToHex(strglobalkey);
string strhex2 = ConvertStringToHex(hexivkey);
byte[] bytes = (byte[])ci.EncryptStringRaw(EB_CRYPT_CIPHER_ALGORITHM.EB_CRYPT_CIPHER_ALGORITHM_DES3_ECB,
strhex1, strhex2, text);
return Convert.ToBase64String(bytes);
the above alogithm returns a string which doesn't match with our targetted string provided by the client.
what should i do to match with the targetted string? The client had generated the encrypted string using PHP.

View 2 RepliesSaving Sessions In SSL Encrypted Cookies Vs. Client Certificates?
Dec 10, 2010Background: From a desktop application, users will navigate to an SSL-encrypted web portal where they will have to enter a username / password if it's their first time logging in. I want to be able to securely persist their user session. I was thinking of using encrypted cookies, storing their username and a unique session token / key, but was wondering what benefits client certificates offered in terms of security.
The way I see understand it currently:
Encrypted cookies:
Saved on the user's machine just like any other cookie Since the entire site is SSL, the contents of the cookie cnnot be tampered withEasily implementableWhen a user logs in again, invalidate the token / key and issue a new one
Problems:
Anyone attempting to access the web portal on the computer with a saved session will be able to, but this is a problem with any persisted session, right?
How do I know that computer A is computer A and not just computer B that copied computer A's cookie?
Client Certificates:
A pain in the ass to install Will uniquely identify that person's computer (or can it be restricted to the user account) to the web portal If the client certificate is stolen, then the account is compromised
Question: For persisting user sessions with the utmost security, would encrypted cookies be sufficient or would I need to install client certificates? How do they differ?
