Hi,

the RSAPrivateKey and RSAPublicKey that you get from NCryptoki are handles to the actual keys on the HSM.

You can read the public key data extracting it from the HSM by following this code: http://wiki.ncryptoki.com/How-to-extract-an-RSA-public-key.ashx

You can read the private key data, only if it is set as "Exportable", by using the code here: http://wiki.ncryptoki.com/How-to-extract-a-private-key.ashx
