Wait: I have it.
I ran:
"sudo strace -o strace_openpcr_writes -e trace=write -p 312"
The "-p 312" part is the process ID of the running OpenPCR app, which I
got with "pidof OpenPCR" (equally could use "top" to see all running
processes and look for OpenPCR..).
The results looked like this (comments with hashes are mine, original
file is attached):
