Big Banyan Tree

Seeing the Dodda Alada Mara (Big Banyan Tree) in Bangalore is an incredible experience, often evoking a sense of awe and serenity. This majestic banyan tree, located in the village of Kettohalli, about 28 kilometers from Bangalore, is over 400 years old and spreads across 3 acres, making it one of the largest trees in India. The vast canopy of interlinked aerial roots and branches showcases the sheer power and beauty of nature. Standing beneath it, you might feel humbled by its age and size, as though you're witnessing a timeless force of life. The cool shade and the tranquil atmosphere of the tree make it a perfect place to connect with nature and experience a sense of calm.

Digital Signature

Digital signature

Digital signature algorithm is the one that makes the receiver believe that the message was sent by the claimed sender, and trust the message.

There are different types of signing techniques for Example Text signer, Xml signer etc.. We used the XML Signer. First I will explain the signing process how it will take place.

User will pass the Data along with the certificate and signing process will sign the Data using the certificate and pass the data with signature and certificate. We are calling this data as digitally signed Data. Receiver will separate the data and signature form the digitally signed data. And make another signature from that data and compare the both signature.

CAPICOM is a discontinued ActiveX control created by Microsoft to help expose a select set of Microsoft Cryptographic Application Programming Interface (CryptoAPI) functions through Microsoft Component Object Model (COM). CAPICOM can be used to digitally sign data, inspect, verify and display their digital signature and/or digital certificate. CAPICOM Version 2.1.0.2, the latest and last version of CAPICOM, is officially supported on Windows Vista. We are using CAPICOM Version 2.1.0.2

Signing Process

• We are passing Data for signing and the certificate information.
• CAPICOM will take the certificate details like Hash algorithm and apply that algorithm to data and get the Hash called it as Message Digest (MD).
• Using this MD and primary key which is present in certificate, it will create the signature
• It will integrate signature certificate and Data. This data is called digitally signed data.

Verify Process

• We are passing the digitally signed data for verification
• It will separate the Data signature and certificate.
• Using data it will create once again the hash (message Digest) let’s say MD1, using certificate primary key and hash algorithm.
• It will get another MD using signature which is passed though digitally signed data, using local key of certificate. Let’s say this MD as MD2
• For verifying the signing it will check the MD1 is equal to MD2 or not.

Struts Life Cycle EXample

• When any struts based web application loaded into serverinitially it will load the ActionServlet class, due to<load-on-startup> tag in web.xml.

• It will read struts-config.xml file, due to <init-param> tag inweb.xml.

• When anybody makes request to the respective webapplication it will display the file which is mentioned in<welcome-file-list> tag of web.xml file.

• When the view page(.jsp) is displayed to the user internally the strutsframework (ActionServlet) will create an object for the formbean class

• Which extends the ActionForm by calling zero argument constructor(default construtor) which is mapped with the Action class path mentioned in .jsp file <html:form action=”/path”> later it will call the reset() and all the getter methods of the form bean class.

• When the user fills the form and submit the input, our form bean class again calls the default constructor, reset(), all setter() methods, validate() methods respectively.

• Validate method return ActionErrors object. If the ActionErrors object contains any error values(ActionError/ActionMessage values) then the ActionServlet calls the input page mapped with respective action class(<action input=”/input.jps”) that page will display to the user with error messages.

• If ActionErrors object is null(doesn’t contains any ActionError/ ActionMessage) then the ActionServlet calls the execute() method of the Action class which is bind with input request (<action path=”/path” type=”package.OurActionClass”).

• execute() method will return ActionForward object. Depend onthe value, again the ActionServlet will call the respectiveview(.jps page) as response and send it back to user.
