| .SH NAME |
| tcti-pcap \- Debugging module with pcapng output |
| .SH SYNOPSIS |
| A TPM Command Transmission Interface (TCTI) module for logging the TPM |
| commands transmitted and received in pcapng format. |
| .SH 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. |
