Awesome.

I just posted in another thread to the mailing list with some examples
where more flexibility would be needed. "PKCS#11 provider issues with
min and max size".

Another example would be to add flexibility to be more crypto "agile".
I.e. when new algorithms come out, for example SHA3. It will be included
in the PKCS#11 spec eventually, and then it takes a decent round-trip
time before it's possible to use through SunPKCS#11. So an example would
be to be able to configure new mechanisms, that does not affect any
other code in SunPKCS11, dynamically.

Yet another example, AWS CloudHSM requires you to use
CKM_RSA_X9_31_KEY_PAIR_GEN instead of CKM_RSA_PKCS_KEY_PAIR_GEN.
Patching SunPKCS11 to use it is trivial (for java programmers that is),
just replace one string with another. If it could be done dynamically
without patching java files it would be much nicer...and more stable as
it survives JDK upgrades.

Cheers,
Tomas
