i need to implement a standard encryption decryption logic across an entire project platform which has different clients implemented using different platforms as follows:
iphone app (objectiv c)
website (classic asp)
webservice (asp.net)
samsung bada app (c++)
the iphone app as well as the website need to send info to webservice using encrypted query strings
the web service then decrypts this and processes the info further
wanted to know the simplest way to achieve this. is there some free and ready to use binary available with an easy to use api to achieve this?
encryption needs to be as secure as possible
edited: currently we use AES on the website and webservice front
I am trying to encrypt/decrypt a file with CAPICOM in javascript. I have to encrypt file with private key and decrypt with public key. But I dont know how to do this with CAPICOM.
View 1 RepliesI have web.config file and it is encrypted completely and hosted in one server,Now I got one requirement to change admin person mail id. So I need to decrypt the web.config file and update the mail id then encrypt the config file again. Please tell me how to do this using aspnet_regiis -pdf commands?
View 1 RepliesThis is meant to be easy ...so ive been told, but still cant get it to work!I have a sql database hosted on a shared server which requires the use of sql authentication.As a result I require to encrypt my sensitive data in the config (connection strings etc).I understand that you can do this using aspnet_regiis etc, but ive been told that as I have no direct acccess to the server, I may need to program the encryption.
I have seen a few examples, but as a novice I have been banging away at this, looking at an errors screen most of the time!
We are designing a .net web application that has an external and internal site.
Both sites need to encrypt data only the internal site needs to decrypt data.
We are wondering what are the best practices for:
Which encryption method to choose?
Where to store the encryption / decryption key?
I used the following command to encrypt my connection string but an error ocurred,
"The connection name'DatabaseConnectionString1' was not found in the applications configuration or the connection string is empty" How can I encrypt it while keeping the application working? What if I move the encrypted application to another computer? Will it work?

View 2 RepliesI have a Triple DES Key generated by java code from a third party vendor. It is a 3 part key.
We need to use this key in our VB.NET application. When I try to combine this key and use it in my app
'Dim desTransform As ICryptoTransform = desCrypto.CreateEncryptor(EncryptKey(Key), EncryptIV(IV))' gives me an error ' Specified key is not a valid size for this algorithm)
I am new to cryptography and do not understand the algorithms well. How can I use the java generated key in our app for encrypt/decrypt.

View 1 RepliesI have to Encrypt and Decrypt Back the Password field in sql server i have used the pwdencrypt and pwdCompare() but i dont have to compare but i have to display the password back using the Decrypt technique Is there any algorithm which i can use only for encryption and decryption of password field?
View 4 RepliesFor our website, we have decided we would like to maintain our user passwords as encrypted binary data in our database. We are using ASP.NET 3.5 to host our site and SQL Server Express 2008 for the database, both running on the same server. When a user logs in and submits a username and password, there will need to be some sort of encryption or decryption in order to verify the credentials. To me, it would appear that there are 3 ways to do this:
1)[C# Encyrption] On User creation, perform encryption in the Web App and submit the encrypted password to the database. To verify credentials at Login, perform the same encryption on the submitted password and ensure that it matches the value stored in the database.
2)[SQL Encryption] On User creation, submit the plain-text password to the database and have it perform one of the SQL encryption variants during INSERT. To verify credentials at Login, have the database perform decryption on the password during the SELECT statement, and compare the plain-text submitted password to the one in the database.
3)[Mix] On User creation, submit the plain-text password to the database, and have it perform one of the SQL encryption variants during INSERT. To verify credentials at Login, perform the same encryption algorithm used by SQL on the submitted password ( is this possible? ), and ensure that it matches the value stored in the database.
Does anybody have an opinion as to which of these options is best? Number 1) is the most familiar to me, and would be the easiest to use with LINQ to SQL ( which is our current data model ), so I am leaning towards that. But if there are better options I would love to know about them.
I am trying to create a list view to provide functionality similiar to the pages in this article(will end up being much simpler in my case)
[URL]
Basically I need three columns. Column 1 will be populated on page load with a list of user names and some data. Clicking on a user from column 1 will query for data regarding that user and bring back multiple rows to be displayed in Column 2. Clicking on data from a row in column 2 will return rows to be displayed in column 3. I am just curious as to how some of you guys would approach this. Ive looked at grouping templates and some articles regarding listviews with multiple rows but. Would it be easier to use 3 seperate listviews? Any ideas or articles to point me in the right direction?
I need good css for Gridview just like the mac css
can we provide the filter functionality to gridview like the excel filter.
Not 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?
here i have in 3-tier architecture , how to pass the data between DAL and BAL. i am using grid view to edit the data,when ever i click on the edit button all the corresponding fields should come to textboxes. i tried for delete ,it works fine bt not working to EDIT.
View 7 RepliesI am building a web site following the tutorials on asp.net. I am using dataset as data access lay, and writing classes to access the dataset. But the example is just basic ideas, how do I retrieve individual table column value in the business layer?For example, if I have a table called Product, I only want to find out what is the product name by product id. I did this in my ProductBLL:
public ProductBLL
{
public int GetProductName(string productId)
{
ProductDataSet.ProductDataTable prodData = Adapter.GetProductById(productId);
[code]...
Is there a better way, or am I doing this correctly? Can anybody give me a reference to a more complicated business logic model?
how the data pass from one layer to another layer in mvc design pattern...
View 2 RepliesI have a browser compatibilty problem with https? I have SSL installed and is in usage. Until today morning, my https part is working well. From then, Https is shown as https(with slashed in red color) saying the page has some insecure content. I have not changed any code and suddenly i see this problem in chrome. In IE 8, i see the same problem but on every page, it shows me a popup if i should allow to opne secure and non secure or just secure. Firefox has no issues . It shows correct https without any problem. I am fed up with it searching all over. Why is this happenening for me in Chrome and IE 8.
View 3 RepliesWhen 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 3 RepliesI want to send socket information to aspx page.eg. I have 80 clients connected to server. Server is doing some calculation based on the user input and if one of the condition is true, it will send the signal to all the connected clients. I'm the client. The other vendor is the server. Currently, my application is windows based, I want to change it to web based. So, When the server send the signal , I want to receive this signal from the web page.
View 1 RepliesI am new to this .NET what is the difference between N-Tier and 3- Tier Architecture. If they are same. How to pass the values from presentation layer to business logic layer.
For Example
I have 10 controls in presentation layer. I passing values to these controls. How the architecture works.
I've even got my JQuery Ajax submission going on now but I've encountered another problem. I *think* it's something to do with the structure I'm using but like I say, I'm fairly newo this.I have my AJAX form submission which builds my "PersonViewModel" (model for the presentation layer) in JSON and sends it to "@Url.Action("RegisterSubmit")" in my Person Controller. Now, I seperate my business layer from my View/presentation layer so in "RegisterSubmit"I'm verifying the model is valid then instantiating a new instance of my business model "Person", adding the values from "PersonViewModel" and then calling my "Save" function.
View 7 RepliesWe're building a large web app that has numerous layers. In order to communicate to the business layer we're using a service layer that the web layer calls when data is needed. Unfortunately, it seems that if exceptions are thrown in the business layer, it seems that the services on the web side are wrapping the exceptions and re-throwing them. We're looking for a clear way to encapsulate the error and log it, without WCF wrapping a new exception around the original.
