p11tool --login --write --load-privkey /mnt/c/Users/Name/Desktop/smctl/linux/privatekey.pem --label "eddsa-key-imported1" --provider /mnt/c/Users/Name/Desktop/smctl/linux/smpkcs11.so
작은 정보
To locate PKCS11 key ID:
Run:
pkcs11-tool --module <path to pkcs11.dll or pkcs11.so> --list-objects
Identify the ID field of the keypair, this is the PKCS11 key ID.
