Security Advice: SmartCard-HSM generates weak AES Keys

Hello, my Nitrokey HSM 2 is up to date, but I cannot generate a symmetric key… I am trying with the APDU commands from the manual, or with pkcs11-tool.

On windows, I type the command :
pkcs11-tool.exe -l --pin 981567 --keygen --key-type aes:128 --id 1
error: Generate Key mechanism not supported

Can someone describe the steps to use to generate the key ?


Edit: moved to Unable to create a symmetric, or secret key on Nitrokey HSM 2
