Check this one explaining basic premise public-key cryptography and how it relates to XML Digital Signatures, detail the creation of a key pair, give examples for signing and verifying an XML document, and discuss different implementations to provide reliable application licensing...

For your exact problem of using Private key you can check here for some inputs...

I have already gone through these links
let me clarify my problem once again
I am developing a web application in asp.net 3.5 framework with C# and in that application i have a rich textbox or multi line text box which contains data of n length and i want to encrypt and decrypt the data using the digital signatures please consider that the user using the web application is already having the digital signatures from a Gov. recognized body and my application will not create any Digital Signature it will only use the .pfx file or the installed signature I am able to open the certificate store and it is displaying all the certificates installed on the computer. now what i need is i want to encrypt the data using the digital signature's public key and decrypt it using the private key of the same digital signature. I may save the public key in the DB for encryption but to decrypt the data we need the digital signature. please Help me its really very urgent.
Thanks and Regards Meetu Choudhary
