In here we refactor certify_credential_with_iak() into a more generic certify_credential() which is able to certify a credential using TPM2_Certify and sign it with the key passed as an argument. We then implement certify_credential_with_iak() in terms of this new function. Signed-off-by: Sergio Correia <scorreia@redhat.com>
As we will soon start using these structs in the challenge-response protocol implementation, let's rename some of them to improve readability. - SessionRequestAuthSupported -> SupportedAuthMethod - SessionIdRequestAuthProvidedData -> ProofOfPossession - SessionIdRequestAtttributes -> SessionUpdateAttributes - SessionIdResponseAtttributes -> AuthenticationResultAttributes Signed-off-by: Sergio Correia <scorreia@redhat.com>
