An abstract interface for a session that can have a policy applied to it.

Required Methods

fn device(&mut self) -> &mut Device

Returns the device associated with the session.

fn policy_pcr( &mut self, pcr_digest: &Tpm2bDigest, pcrs: TpmlPcrSelection, ) -> Result<(), PolicyError>

Applies a TPM2_PolicyPCR action to the session.

Errors

Returns an error if the policy action fails.

fn policy_or(&mut self, p_hash_list: &TpmlDigest) -> Result<(), PolicyError>

Applies a TPM2_PolicyOR action to the session.

Errors

Returns an error if the policy action fails.

fn policy_secret( &mut self, auth_handle: u32, auth_handle_name: &Tpm2bName, password: Option<&[u8]>, cp_hash: Option<Tpm2bDigest>, ) -> Result<(), PolicyError>

Applies a TPM2_PolicySecret action to the session.

Errors

Returns an error if the policy action fails.

fn get_digest(&mut self) -> Result<Tpm2bDigest, PolicyError>

Retrieves the final policy digest from the session.

Errors

Returns an error if the digest cannot be retrieved.

fn hash_alg(&self) -> TpmAlgId

Returns the session’s hash algorithm.
