for selftest location, please refer to #1406 (comment)

[jyao1]

Please add all sym, deterministic asym algo at first.
Then probabilistic asym algo with hardcoded random.

[jyao1]

This is enough as the first patch.

I recommend, we review the design at first, then merge, then continue with rest key exchange or probabilistic algo.

@jyao1 Is this level of granularity ok? For example, if SHA-256 passes but SHA-384 fails, would you like to know that information? Or is any failure deemed fatal?

[steven-bellock]

Only list the algorithms that will be covered. For example SPDM doesn't support SHA1.

[Wenxing-hou]

Thanks. I have made the comments more clear.

[steven-bellock]

You can get rid of the explicit array sizes.

[Wenxing-hou]

Yes. I deleted all explicit array sizes.

[steven-bellock]

For C89 compatibility we don't allow procedural statements until all variables have been declared for a scope. So I would make this bool result = true;.

[Wenxing-hou]

Thanks. I will remember it.
