Bonnie.NET Web Edition - Digital Signature with ASP.NET

DIGITALLY SIGN TEXT, DOCUMENTS OR FORM DATA FROM ASP.NET WEB PAGES

Bonnie.NET Web Edition implements a set of functionalities that permit to generate digital signatures of data by using the PKCS#7 standard.

Data can be digitally signed from ASP.NET web application (client side and/or server side) or inside desktop application.

This standard permits to:

1. Exchange digitally signed data by using a wide adopted format that can be parsed by all cryptographic systems (interoperability) that uses the same standard.

2. Encapsulate, in a single message (a PKCS#7 signed-data message), not only the digital signature computed on some sort of data, but even data itself plus additional useful attributes, such as signature date and time, the public key related to the private key that digitally signed the message and the identity of the public key owner (the signer). Notice that all those extra information are all digitally signed by the subject that signs the message and so they are digitally signed too.

3. Generate multiple digital signature of the same piece of data. The signed-data message can contain an unlimited number of different signatures, each one with its signature date and time, the public key of the signer and the identity of the same.

Bonnie.NET Web Edition, respect to the Standard Edition, introduces some new crypto-objects:

The digital signature generation on the web client is made possible by using theCassandra Client Framework plug-in.
