I got this question on the VMTN forum this week, does the Native Key Provider require a host to have a TPM? (Trusted Platform Module) The documentation does discuss the use of TPM 2.0 when you enable the Native Key Provider. Let’s be clear, the vCenter Server Native Key Provider does not require a TPM! If a TPM is available on each host then it will be used by the Native Key Provider to store the secrets on. But as stated, it is not a requirement. I have asked to get the documentation appended so that it is officially documented as well, just posting it here so that it indexed by google.
