  • EndorsementKeyObject

    This cmdlet generates an EndorsementKeyObject that contains the following members:

    -- IsPresent. A Boolean that represents whether the endorsement public key is known to the operating system.
    -- PublicKey. An AsnEncodedData object that contains the asn.1 encoded public portion of the endorsement key.
    -- PublicKeyHash. The hash, as a String, of the public key if the cmdlet used a hash algorithm.
    -- ManufacturerCertificates. A X509Certificate2Collection object that contains the manufacturer endorsement key certificates. This object can contain the manufacturer and platform certificates.
    -- AdditionalCertificates. A X509Certificate2Collection object that contains a collection of additional endorsement key certificates that are registered to the operating system, such as any enterprise certificates.


Examples

Example 1: Get endorsement key information

This command gets information about the endorsement key of the TPM. The command uses the Sha256 algorithm to hash the public key.
