(PHP ActiveX) 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.
