### Server TLS PKCS #11
|
||||
|
||||
The example server-tls-pkcs11 is a server that uses a private key that has been
|
||||
stored on the PKCS #11 device.
|
||||
|
||||
The id of the private key is two hex bytes: 0x00, 0x01
|
||||
|
||||
Change this to be the id that you set when importing the key.
|
||||
|
||||
## SoftHSM version 2
|
||||
|
||||
# Import private key
|
||||
|
||||
softhsm2-util --import ../certs/server-keyPkcs8.pem --slot $SOFTHSM2_SLOTID --id 0001 --label rsa2048
|
||||
|
||||
## Run server and client
