Welcome to the libtpms wiki! Build Status

Libtpms provides TPM emulation for TPM 1.2 and TPM 2.0 without tying it to a specific storage backend or an interface for receiving TPM commands. One user of libtpms is swtpm.

Note about the TPM 2 preview branch(es)

The TPM 2 preview branch(es) provide TPM 2 support for libtpms. They are experimental in so far as backwards compatibility of the state the TPM 2 writes into its NVRAM file may not be maintained and thus the state written with one version of a preview branch may not be readable by another version. Also while work is ongoing the layout of the written state may change within one branch.

To-do list branch tpm2-preview.rev146

  • TPM2: check that all state is written properly: create test cases for swtpm that have lots of state defined and make sure the state is accessible on big and little endian machines
  • TPM2: clear all FIXMEs
  • TPM2: choose #defines for max. sizes of RSA keys etc.
  • TPM2: determine final size of NVRAM: 64KB
