RSA encryption using javascript

[sri]

Hi
I have a requirement in which i need to encrypt the password using RSA in javascript and save it in the sql server. This is the password which i need to use when connecting to another machine. So i need the password in clear text while connecting. For this i need to use vb.net to decrypt the password in the sql server. I ve gone through the RSACryptoServiceProvider but i am not very clear about how i can use the keys in javascript to decrypt in vb.net
Any help appreciate
regard
