This chapter discusses many of the TPM's small but useful features that didn't fit well elsewhere in this book. Nothing in this chapter is critical for making use of theTPM; however, everything here serves a useful purpose in certain circumstances. We'll begin with the functions with the broadest applicability, including clearing the TPM of data, using the TPM's RNG, managing the TPM's internal configuration information, and creating an archive. Later in this chapter, we'll cover more specialpurpose features such as monotonic counters, delegation, and timing capabilities.
