Assymetric Encryption - Interorperability between Java2, .NET and Openssl

Hi,
I am porting an application from Java to .NET. The application encrypts
data using RSA, and this data is sent to a Linux box where it is decrypted
using
openssl libraries. Public(.crt file) and Private Keys(.key file) are
generated on the Linux box with openssl routines.

The java application uses the following cipher to encrypt the data.

Cipher cipher = Cipher.getInstance("RSA/ECB/PKCSIPadding","BC")

what is the equivalent .NET security provider for this?

I am assuming it is the RSACryptoService Provider. The
RSACryptoServiceProvider however initializes with a CspParameter. How will I
import my .crt public key into a windows key container.

thanks,

Mathew

Hi Matthew,

The easiest thing to do would probably be to load your .crt file into a
Windows key container, then use the RSA CSP to access that key and do your
decryption. I'm not familiar with OpenSSL at all ... would it be easy to
P/Invoke to it and have it import the key for you?
