The Confirm-CAEndorsementKeyInfo cmdlet checks whether the local certification authority (CA) trusts secure hardware, such as a Trusted Platform Module (TPM), for key
attestation. The cmdlet checks the endorsement key or certificate. An endorsement key is permanently embedded in the security hardware. The public portion of the endorsement
key helps to recognize genuine security hardware.

This cmdlet verifies whether the endorsement public certificate connects by means of a certificate chain to an anchor that the CA trusts for key attestation. Specify an X509
certificate by using the Certificate parameter.

This cmdlet checks whether the endorsement public key exists as a file in a folder configured at the local CA for key attestation. Specify the public key by using the
PublicKeyHash parameter.
