Security :: Encryption Algorithm - Encryption Of Data Required In The Coding?
Sep 16, 2010Not sure if I'm posting the question in the right category.
1) I'm working in a project where encryption of data is high priority. Could some one suggest what would be the best encryption method to protect data from being cracked.
I'm using TCP/IP protocol.
2) Is HTTPS totally secured. If I'm using HTTPS, does that mean that there is no encryption of data required in the coding?
Database Encryption Or Application Level Encryption?
Oct 23, 2010When you need to store sensitive data such as CCs or SSNs, do you:1) Build your own encryption routine within the application, define a secret key somewhere in a config file, and then manually encrypt/decrypt data going to the database.2) Push all the problem to the database, using the built in DB capabilities (I think most vendors call it Transparent Database Encryption).What trade-offs have you find for your solution? Does writing your own routine perform poorly when compared to TDE? Is code maintainability, or conversely DB vendor lock-in an issue?

View 1 RepliesJavascript - C# Forms Data Encryption Without SSL?
Aug 26, 2010if I complete a form, the data will be sent to the server as raw plain text which could be read by sniffers.
I want to encrypt form's data client-side (like username, password,...) and then send them to the server.
It seems that there are two ways:
1- Using SSL (in my scenarion, I can't use)
2- Using custom ActiveX control.
3- Using server side dynamic javascript encryption function.

Jul 24, 2010I would like to use the System.Security.Cryptography to encrypt / decrypt my passwords strings for my custom membership provider login.I've read some basic article's but they don't explain much about the process in detail. I've decided to use AES because it is said to replace DES encryption. How can I encrypt and decrypt my password strings in the strongest way possible with AES? I would really like a very detailed explanation about the method to use for this task.
View 1 RepliesAsp - AES Encryption And Key Storage?
Jan 10, 2010A few years ago, when first being introduced to ASP.net and the .NET Framework, I built a very simple online file storage system.This system used Rijndael encryption for storing the files encrypted on the server's hard drive, and an HttpHandler to decrypt and send those files to the client. Being one of my first project with ASP.net and databases, not understanding much about how the whole thing works (as well as falling to the same trap described by Jeff Atwood on this subject), I decided to store freshly generated keys and IVs together with each file entry in the database.
To make things a bit clearer, encryption was only to protect files from direct access to the server, and keys were not generated by user-entered passwords. My question is, assuming I don't want to keep one key for all files, how should I store encryption keys for best security? What is considered best practice? (i.e: On a different server, on a plain-text file, encrypted). Also, what is the initialization vector used for in this type of encryption algorithm? Should it be constant in a system?
C# Library Encryption In C# .net
Mar 28, 2011I was told that there's an encryption library I can use and there's a couple that I can choose from (eg. AES, RSA, etc). I also read something about keys. Are keys something you just generate so you can encrypt and decrypt a series of texts? Do you have to purchase that key? Also, is there a best practice that I need to be aware of in encrypting and decrypting? Is encrypting a password recommended? Would performance be affected?

View 1 RepliesSecurity :: Upgraded .Net From 1.1 To 2.0 - MD5 Encryption Is Different?
Mar 19, 2010I inherited a ASP.Net website. Some changes need to be implemented. The login for the application is encrypted using the md5cryptoserviceprovider class. After upgrading to 2.0, the password is no longer encrypted the same as when it was 1.1.
I left the 1.1 virtual directory and it's still working. On the same box, I loaded the 2.0 code and setup a new virtual directory (which isn't encrypting the same as 1.1).
I copied the section below from the 1.1 machine.config section into the web.config and the 2.0 machine.config.
<machineKey validationKey="AutoGenerate,IsolateApps" decryptionKey="AutoGenerate,IsolateApps" validation="SHA1"/>
Here is the code that is generating the hash.
MD5CryptoServiceProvider encryptionServiceProvider = new MD5CryptoServiceProvider();
var bytes = ASCIIEncoding.ASCII.GetBytes(inputString);

View 2 RepliesConnectionstring Encryption In MVC2 4.0 App?
Nov 16, 2010I have an MVC2 .NET 4.0 app, hosted on TFS 2008 (soon to be TFS 2010) that uses connection strings in web.config to connect to a database on another server. I need to encrypt these connection strings.
As I understand it, I can use aspnet_regiis.exe to encrypt the connectionstring portion of the web.config file, but I have to do it on the deployment machine because the encryption uses the machine name to generate the encryption key.
Now, it seems to me that this represents a problem - every time I deploy my code to the dev server won't it overwrite the web.config file, and need to be re-encrypted? This sort of manual process seems kludgy.
Is my understanding about needing to re-encrypt after deployment correct? If so, is there some way to automate this process? I don't want to forget this or get a new team member who doesn't know the process and have the connectionstring exposed to the world.
