This tool is a direct port of virtee/sev-snp-measure. Motivation to write this port is to integrate measurement calculation into Go tools.
The following limitations apply to this port atm:
- only supports SNP
- only measures the initial firmware
What this port does that virtee/sev-snp-measure doesn't do:
- parse OVMF metadata from a OVMF binary. This can be used (together with OVMFHash) to calculate measurements without having access to the binary.
If you need more features or find a bug please open an issue. For features that virtee/sev-snp-measure provides, addition should be quick.
Pull requests are welcome!

This tool was originally developed for Constellation to verify launch measurements on AWS's SNP instances.
