encryption of url

[Michele Smith]

Hello, how would you do this:

Could you help me figure out how to use querycrypt with java servlets and xsl / xml 1.0:

amp;parentid= <xsl:value-of select=""/> to pass the URL to a different war file's reports.

For example, I am working from a prototype which utilizes .jsp only. Here is the example for the .jsp:

Suppose you had a query string such as the following:
BankID=1234&AccountID=J5678&TrasactionID=25
By definition, a query string consists of name=value pairs seperated by "ampersand". The system will not accept input data of a miss-matched name=value pair.
To encrypt the string in JSP:

<%@ page import="com.guhesan.querycrypt.QueryCrypt" %>
<%
String plainString = "BankID=1234&AccountID=J5678&TrasactionID=25";
String encryptedS = QueryCrypt.getInstance().encrypt(request, plainString);
%>
<A HREF="<%=request.getContextPath()%>/URL_U_WANT_TO_GO.jsp?<%=encryptedS%>">Click here for the secure transaction</A>



Decrypting the query string: Suppose you had a encrypted string such as the following:
someURL.jsp?_tq=c95a29f62075cf63028be5ec6ba48be0
To decrypt in JSP:

<%@ page import="com.guhesan.querycrypt.QueryCrypt" %>
<%@ page import="com.guhesan.querycrypt.beans.RequestParameterObject" %>
<%
RequestParameterObject rpo = QueryCrypt.getInstance().decrypt(request);
%>
