a7682d2639 Adding Extended Cipher feature.
With this new subcommand, Pico HSM will support newer cipher algorithms.
ChaCha20-Poly1305 is the first. It will be based on a custom P2 subcommand to support an arbitrary structure with multiple parameters (AAD, IV, etc.)

pico-hsm-tool.py shall be used.

00279da8d5 Adding Secure Lock to lock the device with a random 256 bit key.
This is an extra layer of security to avoid brute force attacks if PIN is too weak.
At every hard reset (on device plug), the device must be unlocked prior any other command. Once unlocked, the device can be used as usual.

b3bcad9ce6 Making MKEK persistent.
It must be persistent as it encrypts device private key and therefore it must survive across reinitializations.
However, if no PIN is provided to unlock it, it will be lost, as with device private key.

fec02ca733 Removing cvcerts.h dependency.
A python script gets the public key of the device (EF_EE_DEV) and requests to our PKI for a CVC. Once got, it is updated to EF_TERMCA (0x2f02).
termca_pk is now on EF_KEY_DEV and termca is on EF_TERMCA (concat with DICA).
