Decode a PKCS#12 file

I am looking for ways to decode a PKCS#12 file in .NET, I need to extract the private key and any certificates so that i can programatically access the following.

modulus
publicExponent
privateExponent
prime1
prime2
exponent1
exponent2
coefficient

I need this informatio so that i can successfully use PKCS#11 to create a private key and cetificate on a USB token.

I have found a website that uses OpenSSL to output this data. I was pretty excited when I found OpenSSL.NET however the functionallity to split PKCS#12 files hasn't been implemented yet. I was wondering if anyone knew of any altenatives.

Thanks

Solution

I've used bouncy castle API extensibly on a recent project, on its Java port, and it works wonders, flawlessly.

I bet their C# isn't much different, and it does a really good work at what is targeted.
