The design that I'm aiming with this cli interface is that it would be usable for TPM2 interaction for application written shell (bash, fish etc.) scripting languages (i.e. password managers and similar).
When it starts to be easy to combine the subcommands in script this should be in fairly good state.
Import and load support keys in ASN.1 format, which is used by kernel for loading trusted keys. Software crypto for now is with libssl bindings as it is sort for safe-play for crypto (CVEs, security hotfixes, auditing) and also it is what I'm most used to in kernel development (and that is what I ultimately care about).
