TCTI-CMD(7) TPM2 Software Stack TCTI-CMD(7) NAME tcti-cmd - TPM2 Sub-process Command TCTI library SYNOPSIS A TPM Command Transmission Interface (TCTI) module for interaction with a sub-process. DESCRIPTION tcti-cmd is a library that abstracts the details of direct communication with the interface and protocol exposed by a sub-process that can receive and transmit raw TPM2 command and response buffers. The interface exposed by this library is defined in the "TSS System Level API and TPM Command Transmission Interface Specification" specification. EXAMPLES For example, if you wanted to use the tpm2_send(1) command as the sub- process to send data to and from the TPM, one could do so like this: tpm2_getrandom -T "cmd:tpm2_send -s" --hex 4 A more useful example would be connecting to a remote machine using ssh and interacting with the remote machine's TPM as if it were local. This uses tpm2_send(1) on a remote machine and uses ssh as the sub-process to create the tunnel to the remote machine. If encrypted sessions are used, the re- mote machine is blinded to the TPM data and cannot interpose on that traf- fic. tpm2_getrandom -T "cmd:ssh remotehost tpm2_send" -s --hex 4 AUTHOR TPM2 Software Project <https://github.com/tpm2-software/tpm2-tss> SEE ALSO Tss2_Tcti_Device_Init(3), Tss2_Tcti_Socket_Init(3), Tss2_TctiLdr_Initial- ize(3), Tss2_TctiLdr_Finalize(3), tcti-device(7), tcti-socket(7), tcti- tabrmd(7), tpm2-abrmd(8) COLOPHON This page is part of release 4.1.3 of Open Source implementation of the TCG TPM2 Software Stack (TSS2).
