(Ruby) PKCS11 Import a Private Key onto the HSM

See more PKCS11 Examples

Demonstrates how to import an existing RSA private key onto the smartcard/token. The imported key is a token object, meaning it stays on the HSM and exists beyond the end of the PKCS11 session.

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

# This example requires the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

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

# Use the PKCS11 driver (.dll, .so, .dylib) for your particular HSM.
# (The format of the path will change with the operating system.  Obviously, "C:/" is not used on non-Windows systems.

# If our only task for now is to simply import the key, we can ignore the returned handle, 
# other than to check for success/failure.  Otherwise, the handle can be used in other PKCS11 operations.
# This example just creates the key and does not use the returned handle.
