Using RSA to encrypt query string data

If I want to use RSA to encrypt query string data, what is the industry standards for such a thing? I understand how the RSA works. Based upon that alone, I would just need to get the public key. However, I understand that it is safer to use a PKI to obtain that public key?
Can someone tell me what is "best practice" for such a thing?

If the third-party-site supports https:, you do NOT have to encrypt anything yourself. That's what https is for - the communication between the user-agent and the server is encrypted as part of the protocol, and all the complicated parts of insuring a secure channel are handled for you.
If the secure site does not support htpps, then you can't use it. Which begs the question of why you are trying to do secure communication via HTTP POST with an insecure site.
To clarify, so we're sure we're talking about the same scenario - there's your server (A), which generates pages for a user-agent (B), which pages point to a third-party site (C). Are you trying to protect your data from eavesdroppers? Or are you trying to hide it from B?
In the first case, you have two options.
1) If both A and C supports https, then all you need to do is build pages with https: URLs pointing at C, and you're done. B hits A using https: URLs, it gets pages back that point to C using https URLs, lots of crypto-magic happens under the covers without you haveing to worry about it, and your data is protected.
2) If A and/or C do NOT support https, then you have to figure out how to encrypt communications between A and C. This is a private channel - we won't be able to help you much, because we don't know what C is expecting. Whatever C's protocol is, and whatever its key is, is what you'll need to implement in A, in order to talk to C.
(If you're actually trying to hide data from B, while sticking it into a page that B has to render - ew. Just...ew. It's wrong on enough levels that I don't think I can adequately describe them all.)
You asked about best-practices - 1) is it. 2) is not. Don't do that. No offense, but specially given your level of understanding of How Crypto Works, whatever you come up with is really really REALLY likely to be horribly flawed in a way that you won't see.
Crypto is both easier and harder than you think it is. Your best bet is to use the standards that the community has hammered out - your data is much, much safer that way.

Encrypt query string parameters

Hi All,
I have a SharePoint designer workflow email. I want to send encrypted link to users within email. Is there any way to send encrypted query string parameters?
Please guide me how to send parameters with url in email so that users cannot see it.
All suggestions are highly appreciated.
Regards and Thanks

Hi,
Per my knowledge, we can't Encrypt query string parameters in SharePoint Designer.
As a workaround, we can encrypt query string parameters using C# code and store the URL in a list. Then we can get the URL in SharePoint Designer.

Reports 6i Encrypting query string parameters using Web.Show_Document()

I am developing Forms 6i form which initiates a report on our reports server (using rwcgi60) using a call to Web.Show_Document(). However, we pass several parameters to the report from the form which we'd like to encrypt, otherwise they're likely to be abused.
For example, I might have something like:
http://www.myserver.com/dev60cgi/rwcgi60?report=MYREPORT&p_unsecure_param=1234
I am aware of the following document which describes how to use a JavaBean implmentation and client cookie to hide sensitive information using a client side cookie - but this appears to be specific to hiding user logon information - can it be extended to cover any parameter on the query string?
http://www.oracle.com/technology/products/forms/pdf/secure_webshowdoc_rep6i.pdf
...or will I have to provide my own solution - e.g. perhaps using the DBMS_OBFUSCATION encryption and decryption functions to pass an encrypted parameter string to the report, and have the report decrypt the string on the reports server....
I should probably point out that the parameter values are dynamic - not static, so adding an entry to cgicmd.dat isn't going to solve my problem.
Any ideas?
Shane

Frank,
Thanks for confirming this - this is what I had suspected - just wanted to check that there wasn't already some inbuilt functionality which I had overlooked. DBMS_OBFUSCATION_TOOLKIT it is then!

Use condition for assigning query to data provider with Javascript

Hi gurus,
I want to assign a query dynamically to a data provider when the user activated a Tab Panel in a Web Template (BI7).
I can do that easily with the standard function SET_DATA_PROVIDER_PARAMETERS but this action is do each time of the activation of the Tab Panel.
So I try to make a javascript for assign the query to the data provider only one time.
My problem is I havenu2019t found a solution to get the default query assigning to the data provider.
Itu2019s an example of what I try to do with javascipt :
function Load_Query()
var r=GET_DATA_PROVIDER PARAMETER ("QUERYVIEW_DATA_PROVIDER")
if (r <>empty)
executeJS_SET_DATA_PROVIDER_PARAMETERS_R()
Thank you for help,
Franck

Hi Janice,
You can check the Option Display Variable values only once.
Thie you will the variables being displayed only once eventhough they are used in Multiple Data provider.
If you want som variable to be data provider specific, then , you can create a new variable and add it int eh query.
For example in your case let us say COMP1 is the variable for company code used in DP1 and DP2.
If you want a different values to be selected for company code in DP1 and DP2 just replce the variable in DP2 with a new variabel COMP2.
Hope this helps.

Can I encrypt a string with RSA encryption using DBMS_CRYPTO?

We have an web application that does a redirect thru a database package to a 3rd party site. They would like us to encrypt the querystring that is passed using RSA encryption. The example that they've given us (below) uses the RSA cryptographic service available in .NET. Is it possible to do this using DBMS_CRYPTO or some other method in Oracle?
Below are the steps outlined to use the key to generate the encrypted URL
2.1 Initialize Service
The RSA cryptographic service must be initialized with the provided public key. Below is sample code that can be used to initialize the service using the public key
C#
private void InitializeRSA( string keyFileName )
CspParameters cspParams = new CspParameters( );
cspParams.Flags = CspProviderFlags.UseMachineKeyStore;
m_sp = new RSACryptoServiceProvider( cspParams );
//Load the public key from the supplied XML file
StreamReader reader = new StreamReader( keyFileName );
string data = reader.ReadToEnd( );
//Initializes the public key
m_sp.FromXmlString( data );
2.2 Encryption method
Create a method that will encrypt a string using the cryptographic service that was initialized in step 2.1. The encryption method should convert the encryption method to Base64 to avoid special characters from being passed in the URL. Below is sample code that uses the method created in step 2.1 that can be used to encrypt a string.
C#
private string RSAEncrypt( string plainText )
ASCIIEncoding enc = new ASCIIEncoding( );
int numOfChars = enc.GetByteCount( plainText );
byte[ ] tempArray = enc.GetBytes( plainText );
byte[ ] result = m_sp.Encrypt( tempArray, false );
//Use Base64 encoding since the encrypted string will be used in an URL
return Convert.ToBase64String( result );
2.3 Generate URL
The query string must contain the necessary data elements configured for you school in Step 1. This will always include the Client Number and the Student ID of the student clicking on the link.
1.     Build the query string with Client Number and Student ID
C#
string queryString = “schoolId=1234&studentId=1234”;
The StudentCenter website will validate that the query string was generated within 3 minutes of the request being received on our server. A time stamp in UTC universal time (to prevent time zone inconsistencies) will need to be attached to the query string.
2.     Get the current UTC timestamp, and add the timestamp to the query string
C#
string dateTime = DateTime.UtcNow.ToString(“yyyy-MM-dd HH:mm:ss”);
queryString += “&currentDT=” + dateTime;
Now that the query string has all of the necessary parameters, use the RSAEncrypt (Step 2.2) method created early to encrypt the string. The encrypted string must also be url encoded to escape any special characters.
3.     Encrypt and Url Encode the query string
C#
string rsa = RSAEncrypt(querystring);
string eqs = Server.UrlEncode(rsa);
The encrypted query string is now appended to the Url (https://studentcenter.uhcsr.com), and is now ready for navigation.
4.     Build the URL
C#
string url = “https://studentcenter.uhcsr.com/custom.aspx?eqs=” + eqs

The documentation lists all the encyrption types:

Can we create range variable for Query Key Date

Hello Gurus,
Can we create a range variable for Query Key Date ? when I tried to give a range of values for Query Key Date, I am unable to find Range Values option. I found only Single Values.
so, Please let me know if we can use Range variables for Query Key Date ??
Thanks in advance,
Regards,
Aarthi

Hi Aarthi,
This is relevant for the time dependant master data that is being pulled in thw query. Like if you are using a nav attr in the query and this nav attr is time dependant, then which record (from the char master data) is to be pulled into the report, depends upon the key date that you specify.
The default key date value is the date on which the query is executed, that is <Today>.
Hope this helps...

Using multiple key values to find data

Hello, It's me again.
I had a question about bring data out from Database and show on an ADF page on Jdev 11.1.1.3.
And Mr. Daniel Atwood     answered my question with this follow blog he wrote.
http://www.avioconsulting.com/blog/datwood/2012/06/19/using-bpm-process-variable-adf-form-retrieve-database-information-0.
But I have another question on the top of that.
The example Mr.Atwood provided is when you using "one" key value, what if I have two key values, how to set this up?
Here are some details:
I have a table like this
ID     Type_code     Name
0001      05      a-blabla
0002     25      b-blabla
0002     26      b-blabla
0003      08      c-blabla
0003      25      c-blabla
0003     79      c-blabla
What I want to do is after input the ID(0003) and type_code (25), it will show me the result on three input text components in ADF page with value 0003, 25 and c-blabla.
Currently, I can use only ID to query the data, but I would like to use two key values to find the specific data.
Thank you very much for taking time to think about this,
Sincerely,
Viola

Dear Daniel, may I ask one more question please?
what if I have 4 tables?
table1
ID * ID_Type_code * Name
0001 * 11 * abc
0002 * 12 * abcd
0003 * 13 * abcde
table2
ID * OID_type_code * Name
0001 * 22 * abc
0002 * 23 * abcd
0002 * 25 * abcd
0003 * 23 * abcde
0003 * 22 * abcde
0003 * 28 * abcde
table3
ID * OID_type_code * OGAD_line_id * address
0001 * 22 * 1 * a street
0001 * 22 * 2 * b street
0002 * 23 * 1 * c street
0002 * 25 * 1 * d street
0003 * 28 * 1 * e street
0003 * 28 * 2 * f street
0003 * 28 * 3 * g street
table 4
ID OID_type_codeOGAD_line_id*COP_line_id*phone number
0001*22*1*1*2222222222
0001*22*1*2*3333333333
0002*23*1*1*4444444444
0003*28*2*1*5555555555
0003*28*2*2*6666666666
Primary key for each table
table1, primary key is ID
table2, primary key is ID , OID_type_code
table3, primary key is ID , OID_type_code, OGAD_line_id
table4, primary key is ID , OID_type_code, OGAD_line_id , COP_line_id
I would like to show each value in each table in the separate input text fields.
Therefore, this is an advanced question based on the previous one, not only get values from one table but also from several tables based on input for example 0003 and 28 as the ID and OID_type_code?.
Let me know if you need more details,
Thank you so much,
Viola

How can I use today's date as default value in query string filter web part in SharePoint

I have a query string filter on my web part page. I am trying to figure out how I can set it's default value to Today? I can't find anything online...

Hi,
Per my understanding, you might want to set a default value to the Query String Filter Web Part.
It would not be able to set default value to the Query String Filter Web Part with the OOTB features available.
By default, with a Query String Filter Web Part in the current page, we can filter other web part in the same page by adding parameters and values in the address bar
of browser.
If setting the “Query String Parameter Name” of a Query String Filter Web Part as “t”, then we can filter the corresponding connected web part by inputting such an
URL into the address bar:
http://sharepoint/SitePages/Page1.aspx?t=value1
Suppose you want to filter the list view with a value dynamically when user opens this page, as a workaround, we can generate an URL with the parameters needed when
page loaded, then redirect user to this URL afterwards. This can be achieved using JavaScript.
About how to redirect user to other page with an URL:

If i encrypted a large data using rsa,what i can do

if i encrypted a large data,the date size > 1024(rsa keysize),the type of data is
byte[],what i can do

You'll have to block it yourself, and encrypt each block on its own. On the decrypt side, your algorithm needs to expect a series of blocks, and it needs to decrypt them each and rebuild the original plaintext. It's not hard - but you're in for some tedious times with byte[].
And you'll end up with something that runs at a snail's pace - but at least the security will be weaker! It's a very bad answer to encryption. I realize that you know that - but feel free to tell whoever is requiring you to be stupid, that what they're asking you to do is stupid. ;)

How to build dynamic query strings in the query using DB adapter 'Pure SQL'

Dear Forum,
I am building an application which will access DB to fetch some result set. The query involves retrieving data from multiple tables(nearly 10 tables). So I have created a DB adapter using 'execute pure sql' option. With this query works fine, but my inputs parameters will vary. So I need to make my query dynamic to append the query strings at runtime depending on the inputs.
For example I have 3 input variables - input1,input2 and input3 (in my request xsd) which are used in the pure sql query. Now if I get a 4th input parameter input4 in the request, I need to append this to query string as 'AND input4=[some value]' at runtime. Otherwise my query should have only 3 parameters. Please suggest how this can be achieved.
Regards,
Satya.

This is a strange requirement, depending on the columns you have and what are optional in them, one way is to have separate operations and each opeartion will have different inputs and for each operation , a different DB Adapter is called. But this way, it results in more number of operations for the service as well as more number of references in the composite. Even if you pass the column inputs to the SQL procedure, it will result in a large number of if-else cases..
Thanks,
N

Invalid column name in query string - using Format function

In my post just before this one the problem was solved for writing a query string using a date range. The rest of the query string includes the same date field (Call_Date) but formatted as 'MMM-YY'. I get an invalid column name error when I add this field to the query string. Here is the rest of the query string:
strSql = "SELECT Format(CALL_DATE,'mmm-yy'), " _
& "HOME_REGION FROM CCC2.CASE_EPRP " _
& "WHERE (HOME_REGION = 'NCR') AND " _
"(CALL_DATE >= to_date( '1/1/2002', 'MM/DD/YYYY' )" _
& "AND CALL_DATE <= to_date( '2/28/2003', 'MM/DD/YYYY' ))"
In the Access Query tool I can include this field
Format(CALL_DATE,'mmm-yy')
and the query runs fine (I just need to make it dynamic using ADO). But in my ADO query string above, I get the invalid column name error. Is there a way I can include
Format(CALL_DATE,'mmm-yy')
in my ADO query string? I appologize for not being more familiar with Oracle Sql. Any help greatly appreciated.
Thanks again,
Rich

Thank you very much for your reply. I think I'm getting closer to the solution. Just I got an error message
"date format not recognized"
when I add "to_char( call_date, 'mmm-yy' )" to the query string. I tried using all uppercase, but that did not make a difference. Do I need to use to_date inside the to_char maybe?
to_char(to_date(call_date, 'mmm/yy'), 'mmm-yy')
Thanks again for your help.

Pass multiple query strings to url using HTTPWebRequest

I'm trying to read data from API (in Json format) and load it into SQL server using script task in SSIS.
Dim Request1 As System.Net.HttpWebRequest = DirectCast(System.Net.HttpWebRequest.Create(URL), System.Net.HttpWebRequest)
Dim Object1 As [Object]
Dim Response1 As System.Net.HttpWebResponse = Nothing
Dim reader1 As System.IO.StreamReader
Dim myResponseString As String
Request1.Headers.Add("Authorization: Token *****")
Try
Response1 = DirectCast(Request1.GetResponse(), System.Net.HttpWebResponse)
reader 1= New System.IO.StreamReader(Response1.GetResponseStream())
myResponseString = reader.ReadToEnd()
I'm able to do this with the URL. However, the requirement now is to pass different query strings to the URL and load the data into SQL.
Could someone please provide the code sample to achieve this.
Thanks

If we sent you a code you must try and tell that it doesn't work or that's not what I want, this is better than repeating the same question again and again. Here you go another snippet for httpwebrequest with querstrings and tested:
Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
Try
Dim request As HttpWebRequest = DirectCast(HttpWebRequest.Create(New Uri("http://www.google.com?querstring1=1&querystring2=2")), HttpWebRequest)
request.BeginGetResponse(New AsyncCallback(AddressOf ReadCallback), request)
Catch ex As WebException
End Try
End Sub
Private Sub ReadCallback(asynchronousResult As IAsyncResult)
Dim request As HttpWebRequest = DirectCast(asynchronousResult.AsyncState, HttpWebRequest)
Dim response As HttpWebResponse = DirectCast(request.EndGetResponse(asynchronousResult), HttpWebResponse)
Using streamReader1 As New StreamReader(response.GetResponseStream())
Dim resultString As String = streamReader1.ReadToEnd()
Dim result As String = Convert.ToString("Using HttpWebRequest: ") & resultString
End Using
End Sub
