How would I integrate Hardware Security Module encryption with a C# application?
886
A Hardware Security Module (HSM) is a hardware-based security device that generates, stores, and protects cryptographic keys. Secure Proxy uses keys and certificates stored in its store or on an HSM. Secure Proxy maintains information in its store about all keys and certificates.
Hardware Security Modules (HSMs) are hardened, tamper-resistant hardware devices that strengthen encryption practices by generating keys, encrypting and decrypting data, and creating and verifying digital signatures. Some hardware security modules (HSMs) are certified at various FIPS 140-2 Levels.
A Hardware Security Module (HSM) is a physical device that provides a secure environment for the storage of cryptographic keys and for performing operations using these keys.
We used Pkcs11Interop and it worked really well. It is an Apache 2.0 licensed open source library. As far as i see it is quite up to date and still being maintained.

If its a PKCS #11 compliant device, you can use NCryptoki. From their website:
NCryptoki is a library for .NET framework that implements the PKCS#11 specifications and supplies an API for C#, VB.NET, Visual Basic 6, Delphi and other COM interop languages for integrating a PKCS#11 compliant token in any application.
[...]
Main Features:
- Compliant with PKCS#11 2.20 specifications
- Compliant with any PKCS#11 smart card/token/HSM
- 32 or 64 bit platform
- .NET Framework 2.0, 3.0, 3.5 and 4.0
