This post discusses how to retrieve a Microsoft Windows 8 or later product key from your firmware using an updated, and enhanced, UEFI Shell utility which I initially developed in 2014.

In this post, I discuss a number of key TPM 2.0 features such as multiple algorithm support and PCR banks, and provide the source code for a UEFI shell utility to display the digests from the first 24 PCRs of a TPM 2.0 implementation. If you are preparing for the RHCSA exam, this post should be of interest to you. I provide a Bash script which will fully configure a simple OpenLDAP directory server which you can then use to test that your OpenLDAP client setup is correct. This is the first in a series of posts which demonstrate how to access, use and modify TPM 1.2 and TPM 2.0 resources via a series of UEFI shell applications. In this post I provide the source code for a simple UEFI shell utility to display the TCG TPM 1.2 event log. |
