Is there any example and idea for implementing encrypt and decrypt function in MSN for text by using plug-in( without using script in Messenger Plus!)? As i want compare the efficiency between this both method.I wish to use AES standard(Rijndael) in this work and visual c#.net.

Another thing i wish to do is encrypt file transfer via msn conversation .Now i just able to encrypt the text file with.txt extension. I plan to extend this function to image(.jpeg), excel file(.xls) as well. thanks and Welcome for any idea and suggestion.Thanks...
