Import an SSH Key to an HSM using PKCS11

See more PKCS11 Examples

Demonstrates how to import an SSH private key to an HSM (smartcard or token).

Note: This example requires Chilkat v9.5.0.96 or later.

// Note: Chilkat's PKCS11 implementation runs on Windows, Linux, Mac OS X, and other supported operating systems.

// For example:
loo_Pkcs11.SharedLibPath = "C:/Program Files (x86)/Gemalto/IDGo 800 PKCS#11/IDPrimePKCS11.dll"

// Let's provide a few attributes to help us find the this key at a later time.
// See SSH Public-Key Authentication using an HSM

// The ID is byte data, so it should be base64 or hex.

// You can provide any ID of your choice.  It is optional.
