DESCRIPTION

simple-tpm-pk11 Is a PKCS11 provider for TPM chips. Its primary purpose is to protect SSH client keys so that they can't be copied or stolen if the machine they're on gets compromised.

OPTIONS

Since PKCS11 modules are .so files loaded by other binaries, they don't take command line options. Instead simple-tpm-pk11 options can be set up environment variables.

SIMPLE_TPM_PK11_DEBUG

If set, enables debug level logging.

SIMPLE_TPM_PK11_CONFIG=/path/to/config

Override default config location. Default is ~/.simple-tpm-pk11/config.

SIMPLE_TPM_PK11_LOG_STDERR

If set, copies all log output to STDERR.

CONFIGURATION FILE

Configuration options are of the key/value variety, with comments lines starting with "#".

key key file

Full path to key file, or relative to ~/.simple-tpm-pk11. This the only required configuration option.

debug

Enable debug level logging.

srk_pin PIN

Set SRK PIN. Default is the Well Known Secret (20 nulls).

key_pin PIN

Set key PIN.

log log file

Full path to log file, or relative to ~/.simple-tpm-pk11.

EXAMPLES

# Load key from ~/.simple-tpm-pk11/my.key.
key my.key
# Load key from /keys/foo/my.key, and the empty string as SRK PIN.
key /keys/foo/my.key
srk_pin

TPM-TROUBLESHOOTING

TODO.

DIAGNOSTICS

Most errors will probably be related to interacting with the TPM chip. Resetting the TPM chip and taking ownership should take care of most of them. See the TPM-TROUBLESHOOTING section.
