PKCS#11: Which CKK_types are supported by CKM_PKCS5_PBKD2?
I am not familiar with that specific Solaris library (is that a software token?).

However, what I can say is that PKCS#11 does not set any minimum requirement for the algorithms that a certain implementation should offer. CKK_IDEA could be supported, but only if the implementer chooses to. For instance, up to a few years ago, IDEA was patented and it was often not included in libraries and devices for legal reasons.

Besides, that is there any good reason not to use CKK_AES? That is the best choice in most cases.
