Hi @martinuy,
Thanks for your proposal, I left four comments. Two of them are
suggestions/ideas, but unless my static analysis is bogus, I also found a minor
bug (one comment explains the reasoning, the other suggests a low-hanging fruit
test case to confirm).

Have you considered removing `PCKK_TLSPREMASTER`, `PCKK_TLSRSAPREMASTER` and
`PCKK_TLSMASTER` from everywhere? We could just use `CKK_GENERIC_SECRET` for
the `TlsPremasterSecret`, `TlsRsaPremasterSecret` and `TlsMasterSecret` key
info entries.
Unlike `PCKK_ANY`, which is used for the `TemplateManager` to map `*` entries
in _SunPKCS11_ configuration files [1], these other 3 pseudo key types are only
used here in `P11SecretKeyFactory`. Additionally, any time these 3 pseudo key
types are used, it is to map to `CKK_GENERIC_SECRET`.
[1] _SunPKCS11_ configuration files can't contain `PCKK_TLS*MASTER` attributes
entries, only `*` is parsable, and corresponds with `PCKK_ANY`:

I suggest adding a case with an invalid key algorithm whose key info map entry
doesn't have `KeyInfo.keyType=CKK_GENERIC_SECRET`. For example,
`PBEWithHmacSHA224AndAES_256`, where `KeyInfo.keyType=CKK_AES`.
