Frequently asked questions about TPM event log viewer
Where do I find my TPM event log on Linux?
Usually at `/sys/kernel/security/tpm0/binary_bios_measurements`, but you must copy it first: `sudo cat /sys/kernel/security/tpm0/binary_bios_measurements > log.bin` because the browser sees it as size 0.
Is my data secure when I parse a TPM event log here?
Yes. The file is read and parsed entirely in your browser by WebAssembly and is never uploaded, stored, or transmitted to any server.
Can I use this tool offline?
Yes, after the page loads, you can disconnect from the network and the parser will continue to work.
How do I use the parsing function directly?
Call `goParseEventlog(bytes, "SHA256")` from the browser developer console to work with the result directly; it returns `{value, error}`.
