John,

 Currently opencryptoki supports 3 hardware token types, in addition to
it's software (OpenSSL based) token:

 * The ICA token, supporting Clear-Key operations for CEX2A and CEX3A
cards (System z)
 * The CCA token, supporting Secure-Key operations for CEX2C and CEX3C
cards (also System z)
 * The TPM token, where the key hierarchy and some operations can be
done via a Trusted Platform Module (multiple architectures).

There are other "legacy" token types in the tree (bcom, aep, etc) but
it's been a long time since they are un-maintained.

I don't believe that the Sun Crypto Accelerator maps to any of those,
but patches are (very) welcome.


As to being "transparent" to the application, the application just
needs to support exploiting PKCS#11 tokens. How this is done and what
can be off-loaded is very application-specific.
