SYNOPSIS
stpm-exfiltrate [ -hOps ] -k key file
DESCRIPTION
stpm-exfiltrate extracts a key that is otherwise protected by the TPM chip. This only works if the key is "migratable" (meaning it was generated in software), and the TPM owner password is known.This is why you should generate keys in hardware (the default) with stpm-keygen and not use its -S option.
OPTIONS
- -h
- Show usage info.
- -k key file
- Key blob file to read.
- -O
- Use Well Known Secret for owner password. Default is ask.
- -p
- Ask for key PIN / password. Default is Well Known Secret.
- -o
-
Ask for SRK PIN / password. Default is Well Known Secret.
EXAMPLES
stpm-exfiltrate -k ~/.simple-tpm-pk11/my.key Enter owner password: blah blah [ ... key data here ...] stpm-exfiltrate -p -k ~/.simple-tpm-pk11/my.key Enter owner password: blah blah Enter key PIN: my secret password here [ ... key data here ...] stpm-exfiltrate -sp -k ~/.simple-tpm-pk11/my.key Enter owner password: blah blah Enter key PIN: my secret password here Enter SRK PIN: 12345678 [ ... key data here ...]
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 of simple-tpm-pk11(7).
