Path to the platform credential for your TPM. Your TPM manufacturer may have provided you with a set of credentials (certificates) that should be used when creating identities using your TPM. When a user of your TPM makes an identity, this credential will be encrypted as part of that process. See the 1.1b TPM Main specification section 9.3 for information on this process.
