.NET support for PKCS#11?

Question

Does the System.Security.Cryptography.Pkcs namespace have support for PKCS#11?

Answer 1

Based on the information on MSDN, it appears that only PKCS 7 and 9 are supported.

Answer 2

This company seem to have a PKCS#11 wrapper for .NET, but I have never used it [no affiliation].

Answer 3

Microsoft's cryptography support for custom external software is typically done through a "CSP".

There exists at least two implementations of Microsoft CSP on top of PKCS#11:

• IDAP11 : Bundled with the ID Ally (http://www.identityalliance.com)
• CSP11 : http://csp11.labs.libre-entreprise.org/

You may want to look at the following MSDN article for reference on how to use a CSP:

Answer 5

You can use NCryptoki, that is a .NET PKCS#11 wrapper to native PKCS#11 modules and allows to call PKCS#11 function in C# as well as vb.net. See this url for more information: http://www.ncryptoki.com
