Checks that (hash of the) KATs (in NIST format) produced on this platform matches
|
|
the one provided in the META file for every scheme/implementation.
|
|
|
|
Note that this only uses the first test case from the NIST-format KAT files.
|
|
The appropriate hash can be generated from the original submission's KAT file
|
|
using the command:
|
|
cat PQCkemKAT_whatever.rsp | head -n 8 | tail -n 6 | sha256sum
