  30  * Dual-Function Cryptographic Functions
  31  * (as defined in PKCS#11 spec section 11.13)
  32  *
  33  * These functions will not be supported in the this release.
  34  * A call to these functions returns CKR_FUNCTION_NOT_SUPPORTED.
  35  *
  36  * Providing the support for dual-function crypto functions is
  37  * not trivial.  C_FooInit() need to be called for the 2 crypto
  38  * operations before any of these function can be called.
  39  * When C_FooInit() is called, metaslot doesn't know if it is going
  40  * to do dual-function crypto or single crypto operation.
  41  * So, it has no way to pick the slot that supports both the mechanism
  42  * it specified and supports dual-functions.
  43  *
  44  * In order for these dual functions to be supported in the future,
  45  * metaslot need to simulate the dual-function crypto operations
  46  * when both operations are not lucky enough be to initialized in
  47  * the same slots that supports dual-functions.
