Asymmetric #TPM2 #keys v7:

https://lore.kernel.org/linux-crypto/20240528210823.28798-1-jarkko@kernel.org/T/#mb07f85a8c3f4af388cbc08438e71ac8aea447d85

This is the first version with fully working #ECDSA signing and signature verification with the public key.

Implementation notes:

  1. Accepts only sha256 at this point. Can be easily extended later. It is best overall choice for the first version.
  2. Does not accept any authentication policy yet. Can be extended later by adding a new parameter to match_table_t param_keys in security/keys/keyctl_pkey.c. E.g. "policy=%s".

I’m pretty happy with this, given that I did it fully during 1.5 week period on my free time and unpaid ;-)
