Hi there, I am using Esys_TR_FromTPMPublic() in an application to get a Esys TR handle for an NV-index, it works well when I use no sessions but the ESYS spec recommends to use a salted HMAC session when reading NV-index with this command. But when I use a salted HMAC session I get an "attribute mismatch" error on the session from the TPM. Looking through the library specification I understand that the NV_ReadPublic command, which is used by Esys_TR_FromTPMPublic(), only accepts audit and encrypting sessions, but not simple salted HMAC sessions. So how should I go about using Esys_TR_FromTPMPublic() with salted HMAC sessions? Or how should I go about ensuring the data I get from the TPM (e.g., name) for the NV-index can be trusted? BTW, the tpm2-tss version installed on my test system is 2.3.2 Thanks, Diego -- Diego Santa Cruz, PhD Technology Architect spinetix.com
