Windows TPM 2.0 storage root key (SRK) public key location and size

221 views Asked by At

What is the correct way to read the SRK public key in Windows. In Linux it was simple to use

tpm2_readpublic -c 0x81010001

I see a standard RSA 2048 public key.

I didn't find any easy way to read it in Windows. I searched in the registry and opened

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\TPM\WMI\Admin\

But the value there does not look long enough to be RSA 2048 bit key? Is it really that Windows uses ECC for SRK?
