Detailed Description

CK_MECHANISM; CK_MECHANISM_PTR

CK_MECHANISM is a structure that specifies a particular mechanism and any parameters it requires.
mechanismthe type of mechanism
pParameterpointer to the parameter if required by the mechanism
ulParameterLenlength in bytes of the parameter

Note that pParameter is a "void" pointer, facilitating the passing of arbitrary values. Both the application and the Cryptoki library must ensure that the pointer can be safely cast to the expected type (i.e., without word-alignment errors).

CK_MECHANISM_PTR is a pointer to a CK_MECHANISM.

CK_MECHANISM_INFO; CK_MECHANISM_INFO_PTR

CK_MECHANISM_INFO is a structure that provides information about a particular mechanism. It is defined as follows:
