Daniele Lacamera cc447ea879 Support for hybrid authentication (2 ciphers) 2024-10-30 13:17:06 +01:00
David Garske 758eda1ad4 Add support for sealing/unsealing a secret with auth. 2023-10-25 13:24:27 +02:00
David Garske e3f97f401e Fix for ROT with no auth. Add test case for it. 2023-09-15 07:25:01 +02:00
David Garske c04960c097 Fix simulator to not just while(1) on panic, which causes CI to spin/timeout (instead exit with error). Fix ROT logic and make sure read error code gets passed up stack. 2023-09-12 12:26:48 +02:00
David Garske 2349a68e76 Added support for storing sealed blobs into NV. Refactor the TPM signature verify to use existing load public key function and generic verify hash TPM function. Added support for RSA sign with ASN.1 encoding (Example: `SIGN=RSA2048ENC`). 2023-09-12 12:26:48 +02:00
David Garske 490286be7d Support for sealing/unseal a secret based on an externally signed PCR policy. 
* Added new `WOLFBOOT_TPM_SEAL` and `WOLFBOOT_TPM_SEAL_NV_BASE` config options.
* Added new `tools/tpm/policy_create` tool for assisting with creation of a policy digest. The sign keytool `--policy=file` signs the policy.
* Added new `WOLFBOOT_TPM_VERIFY` option to enable offloading of the asymmetric verification to the TPM. By default wolfCrypt will be used.
* Added example seal/unseal to update_flash for ARCH_SIM.
* Renamed `WOLFBOOT_TPM_KEYSTORE_NV_INDEX` to `WOLFBOOT_TPM_KEYSTORE_NV_BASE` to support multiple public keys.
* Refactored most TPM code into tpm.c.
* Refactored the keystore ROT to use new `wolfBoot_check_rot` API.
* Refactored the sign keytool to have a sign_digest function to allow signing firmware and policy for sealing/unsealing.
* Fix for make distclean && make using the wrong key tools.

David Garske 19424c86c9 Added optional `WOLFBOOT_TPM_KEYSTORE_AUTH` for build-time NV auth. 2023-08-22 07:12:05 +02:00
David Garske 9ca58248e4 Adding GitHub Action for testing TPM features. 2023-08-17 13:43:58 +02:00
