TCTI-PCAP(8)

NAME
tcti-pcap - Debugging module with pcapng output

SYNOPSIS
A TPM Command Transmission Interface (TCTI) module for logging the TPM commands transmitted and received in pcapng format.

DESCRIPTION
tcti-pcap is a library that logs TPM commands and responses and forwards them to another TCTI module. The child TCTI module will be loaded by the tss2-tctildr library. The config string passed to tcti-pcap specifies the child TCTI module to be loaded. For instance, passing "pcap:device:/dev/tpm0" to tss2-tctildr will result in tcti-pcap being loaded which will forward the TPM commands to the tcti-device module. The pcapng data is stored in a file tpm2_log.pcap. This path can be altered using the environment variable TCTI_PCAP_FILE. The strings "stdout"/"-" and "stderr" are valid values.
